Figuring out how much mortgage you can afford isn’t a guessing game. It’s a math problem, and like any math problem, it has a real answer once you plug in the right numbers.
If you’re buying a home in Richmond, Henrico, Chesterfield, Midlothian, Short Pump, Fredericksburg, or anywhere across Virginia, you’re working in a market with real price pressure. Henrico County median home prices currently run in the $390,000–$430,000 range. The 2026 conforming loan limit sits at $806,500. These aren’t abstract numbers — they directly shape which loan programs you qualify for and what your monthly payment will look like.
This guide walks through the affordability question in six concrete steps. By the time you finish, you’ll have a working affordability number, understand the ratios lenders use to evaluate your application, know which loan program fits your financial profile, and see exactly what a real monthly payment looks like across current rate ranges.
One important note before you start: you don’t need to run a credit check to begin this process. Mortgage Mastermind offers a NoTouch Credit pre-qualification using Vantage Score 4.0 — a soft pull that gives you a real affordability picture without any impact to your credit score. That means you can explore your numbers freely, without risk, before making any commitments.
Let’s get into the math.
Step 1: Calculate Your Gross Monthly Income — The Foundation of Every Affordability Number
Every affordability calculation starts in the same place: your gross monthly income. Not your take-home pay. Not what hits your bank account after taxes. Lenders use pre-tax, pre-deduction income — and this distinction matters more than most borrowers realize.
Using net income instead of gross is one of the most common mistakes first-time buyers make. It overstates what you can afford and sets up disappointment when the lender’s numbers come back lower than expected.
For W-2 Employees: The calculation is straightforward. Take your annual salary and divide by 12. A $75,000 annual salary equals $6,250 gross monthly income. If you have a base salary plus documented overtime, you can include overtime — but only if you have a two-year history of receiving it. Lenders want to see that it’s consistent, not a one-time event.
For Self-Employed Borrowers: This is where it gets more nuanced. Lenders use a two-year average of your net income from tax returns — Schedule C for sole proprietors, K-1 from an 1120S for S-Corp owners. The challenge is that legitimate business write-offs reduce your taxable income, which also reduces your qualifying income. A borrower earning $95,000 per year with $15,000 in business deductions may qualify on roughly $80,000 — or less, depending on how the income is structured.
If you write off heavily, a bank statement loan program may be a better fit. These programs use 12–24 months of business or personal bank deposits to calculate qualifying income, bypassing the tax return entirely. This is especially useful for contractors, consultants, real estate investors, and business owners in markets like Richmond and Chesterfield who have strong cash flow but modest taxable income. Borrowers in this situation should review income verification strategies for mortgage qualification before applying.
Secondary Income Sources: Other income types can be included when properly documented.
Rental income: Lenders typically use 75% of gross rental income to account for vacancy and maintenance.
Part-time employment: Requires a two-year history at the same employer or in the same field.
Alimony or child support: Includable if documented in a court order and likely to continue for at least three years.
Worked Example Table
The table below shows how gross monthly income is calculated across different income types:
W-2 Employee | $75,000/yr salary | $75,000 ÷ 12 = $6,250/mo gross
Self-Employed | $95,000/yr revenue, $15,000 write-offs | Qualifying income may be closer to $6,667/mo or lower depending on return structure
W-2 + Rental | $75,000 salary + $2,000/mo gross rent | $6,250 + ($2,000 × 75%) = $7,750/mo gross
The bottom line: always start with gross income. It’s the number your lender will use, and it’s the number that drives every calculation that follows.
Step 2: Apply the Two DTI Rules Lenders Actually Use
Once you know your gross monthly income, lenders apply debt-to-income ratios — DTI — to determine how much of that income can be committed to housing and total debt obligations. There are two ratios to understand: front-end DTI and back-end DTI.
Front-End DTI (Housing Expense Ratio): This is your total monthly housing cost — principal, interest, property taxes, homeowners insurance, HOA fees, and mortgage insurance if applicable — divided by your gross monthly income. This is sometimes called PITI (Principal, Interest, Taxes, Insurance).
Back-End DTI (Total Debt Ratio): This takes all monthly debt obligations — housing plus car payments, student loans, minimum credit card payments, personal loans — and divides by gross monthly income. This is the number most lenders focus on when evaluating qualification. For a deeper breakdown of how these ratios affect your application, see this guide on debt to income ratio for mortgage qualification in Virginia.
DTI thresholds vary by loan program. Here’s how they break down:
Conventional Loans: Front-end guideline approximately 28%; back-end up to 45–50% with strong compensating factors (high credit score, significant reserves).
FHA Loans: Front-end guideline approximately 31%; back-end up to 43–57% with Automated Underwriting System (AUS) approval. FHA is more flexible for borrowers with higher debt loads.
VA Loans: No official front-end cap. Back-end guideline is approximately 41%, but can exceed this with sufficient residual income. VA uses a residual income test as an additional layer of affordability analysis. See VA loan guidelines at VA.gov.
USDA Loans: Front-end 29%; back-end 41%. Both can go higher with AUS approval. USDA is available in eligible rural and suburban Virginia counties including Goochland, Louisa, Caroline County, Lake Anna area, and parts of Hanover.
Jumbo Loans: Typically 43% back-end maximum. Stricter reserve requirements apply. Less flexibility than government-backed programs.
Worked DTI Math: Using the $6,250 gross monthly income from Step 1, here’s how the back-end DTI calculation works in practice.
$6,250 × 43% back-end DTI limit = $2,687 maximum total monthly debt payments.
If your existing monthly obligations include a $350 car payment, $150 student loan minimum, and $100 in credit card minimums — that’s $600/mo in existing debt.
$2,687 − $600 = $2,087 maximum allowable PITI (housing payment).
That $2,087 figure is your ceiling. It includes principal, interest, property taxes, homeowners insurance, any HOA fees, and PMI if applicable. It’s not just the loan payment — it’s the full housing cost.
For additional DTI guidance, the Consumer Financial Protection Bureau publishes clear explanations at consumerfinance.gov.
Understanding your DTI before you start shopping gives you a realistic target range — and helps you have a more productive conversation with a lender from the start.
Step 3: Translate Your Max Payment Into a Loan Amount — With Real Rate Math
You now have a maximum PITI figure. The next step is working backward from that number to find the loan amount it supports. This is where interest rates become critical — because the same loan amount costs dramatically different amounts per month depending on the rate.
A $300,000 loan at 6.5% carries a meaningfully different payment than the same loan at 7.5%. Understanding this relationship helps you see exactly how rate movements affect your purchasing power. Tracking mortgage rate trends in Virginia can help you time your purchase and lock strategy more effectively.
Payment Factor Table (Principal + Interest Only, Per $1,000 Borrowed, 30-Year Fixed):
5.5% rate: approximately $5.68/mo per $1,000 borrowed
6.0% rate: approximately $6.00/mo per $1,000 borrowed
6.5% rate: approximately $6.32/mo per $1,000 borrowed
7.0% rate: approximately $6.65/mo per $1,000 borrowed
7.5% rate: approximately $6.99/mo per $1,000 borrowed
To find your maximum loan amount, divide your available P&I budget by the payment factor, then multiply by 1,000.
Worked Example 1: From the DTI math in Step 2, the maximum PITI was $2,087. Now subtract estimated taxes and insurance to find the P&I budget.
Virginia property tax rates vary by locality. Chesterfield County runs approximately $0.95 per $100 of assessed value; Henrico County approximately $0.87 per $100. On a $350,000 home in Chesterfield, annual taxes would be approximately $3,325, or about $277/mo. Homeowners insurance in Virginia typically runs $100–$180/mo depending on coverage level and home value.
Using $277/mo taxes and $130/mo insurance: $2,087 − $277 − $130 = $1,680 available for principal and interest.
At a 6.5% rate: $1,680 ÷ $6.32 × $1,000 = approximately $265,823 loan amount.
At a 7.0% rate: $1,680 ÷ $6.65 × $1,000 = approximately $252,632 loan amount.
That’s a difference of roughly $13,000 in purchasing power from a single half-point rate change. Rate shopping isn’t optional — it’s one of the most impactful financial decisions in the entire transaction. Learn how to lock in a mortgage rate at the right moment to protect your purchasing power.
Worked Example 2: A borrower with $2,000 available for P&I at 7.0% rate: $2,000 ÷ $6.65 × $1,000 = approximately $300,752 loan amount.
Important Benchmark: The 2026 conforming loan limit is $806,500. Loan amounts above this threshold move into jumbo territory, which carries stricter qualification requirements including higher credit score minimums, larger down payments, and more reserve requirements. For most Virginia buyers in Richmond, Henrico, Chesterfield, and surrounding counties, the conforming limit provides ample room — but buyers in higher-price neighborhoods of Short Pump or Glen Allen should be aware of where their loan amount falls relative to this threshold.
Step 4: Factor in Down Payment, Closing Costs, and Cash-to-Close Requirements
Knowing your maximum loan amount is only part of the picture. You also need to know how much cash you need to bring to closing — and how your down payment choice affects your monthly payment and long-term costs.
Down Payment Requirements by Loan Type:
Conventional: 3%–20%+. Down payments under 20% trigger Private Mortgage Insurance (PMI), which adds to your monthly payment.
FHA: 3.5% with a 580+ credit score; 10% with a 500–579 credit score. Requires both upfront and annual mortgage insurance premium (MIP). See current FHA guidelines at HUD.gov.
VA: 0% down for eligible veterans, active-duty service members, and surviving spouses. No PMI required. One of the most powerful financing tools available.
USDA: 0% down in eligible rural and suburban Virginia areas. Counties like Goochland, Louisa, Caroline County, Lake Anna area, and outskirts of Hanover frequently qualify. No PMI, though a guarantee fee applies.
Jumbo: Typically 10%–20%+ depending on the lender and loan amount. Stricter qualification standards throughout.
The PMI Cost Impact: On a conventional loan under 20% down, PMI typically adds $50–$200/mo to your payment depending on loan size, credit score, and LTV ratio. This cost directly reduces your P&I budget from Step 3. Understanding exactly what mortgage insurance costs and when you can drop it is essential before choosing your down payment amount. PMI drops off automatically once you reach 20% equity, either through payments or appreciation.
Closing Costs in Virginia: Expect 2%–4% of the loan amount. On a $350,000 loan, that’s $7,000–$14,000 in closing costs. These include lender fees, title insurance, recording fees, prepaid taxes and insurance, and other settlement charges. This is separate from your down payment — both are needed at closing. For a detailed breakdown, review this guide to mortgage closing costs in Virginia.
Breakeven Math on Down Payment Decision: Should you put 10% down or stretch to 20%? Here’s how to think through it with real numbers.
On a $300,000 home: 10% down = $30,000 with approximately $150/mo PMI. 20% down = $60,000 with no PMI. The extra $30,000 invested saves $150/mo.
Breakeven calculation: $30,000 ÷ $150/mo = 200 months, or approximately 16.7 years.
If you plan to sell or refinance before 16–17 years, the smaller down payment and keeping the extra $30,000 liquid may be the smarter financial move. If you’re planning to stay long-term and the PMI payment meaningfully strains your budget, the larger down payment makes sense. Neither answer is universally correct — it depends on your timeline and opportunity cost for that capital.
Cash Reserves After Closing: Most loan programs require 2–6 months of PITI in liquid reserves after closing. Jumbo loans often require 12 months. This means your cash planning needs to account for down payment, closing costs, and reserve requirements simultaneously.
One option worth exploring in slower markets: seller concessions. In parts of Fredericksburg, Stafford, and Spotsylvania where inventory has been more balanced, sellers have shown more willingness to contribute toward closing costs, which can meaningfully reduce the cash you need at closing.
Step 5: Check Your Credit Score Range — And Understand How It Shifts Your Affordability
Your credit score doesn’t just determine whether you qualify for a mortgage. It determines what rate you receive, which directly affects your monthly payment and maximum loan amount. A difference of 40–60 points on your credit score can translate to a meaningful rate difference on a $300,000 loan — and that rate difference compounds across 30 years of payments.
Credit Score Thresholds by Loan Program:
Conventional: 620 minimum to qualify; best pricing typically requires 740+. The pricing improvement from 720 to 760 is real and worth pursuing if you’re close.
FHA: 580 for 3.5% down; 500–579 qualifies for 10% down. FHA is specifically designed to serve borrowers who haven’t had the opportunity to build perfect credit.
VA: No official minimum set by VA guidelines. Most lenders apply a practical floor of 580–620. VA’s residual income test provides additional flexibility that conventional underwriting doesn’t offer.
USDA: Typically 640+ for automated underwriting approval. Manual underwriting may be available in some cases below that threshold.
Jumbo and Non-QM: Varies by lender and program. Bank statement loans for self-employed borrowers often start at 620+, though some programs require higher scores depending on LTV and loan size.
The NoTouch Credit Advantage: Here’s something most borrowers don’t know: you don’t have to submit to a hard credit pull just to understand your affordability. Mortgage Mastermind offers a soft-pull pre-qualification using Vantage Score 4.0 — the same scoring model used by many lenders — that gives you a real picture of where you stand without any impact to your credit score. Learn more about how no credit check prequalification works for Virginia homebuyers.
A soft pull is used for pre-qualification and initial rate exploration. A hard pull is a formal credit inquiry that appears on your credit report and can temporarily affect your score by a few points. The hard pull only needs to happen when you’re ready to move forward with a formal application — not during the shopping and exploration phase.
This matters because many borrowers hesitate to start the mortgage process out of fear of damaging their credit. The NoTouch Credit approach removes that barrier entirely. You can get a real affordability number, understand which programs you qualify for, and explore rate scenarios — all without a credit hit.
If your score falls below the threshold for your target program, the path forward is clear and actionable. Mortgage Mastermind works with credit scores down to 500 on FHA programs. Borrowers who have been turned down by banks or credit unions are often convertible when the right loan program is matched to their actual credit profile rather than a one-size-fits-all standard. If you need to raise your score before applying, this step-by-step guide on how to improve your credit score for a mortgage outlines exactly what to prioritize.
Step 6: Match Your Affordability Profile to the Right Loan Program — Then Get Pre-Approved
You’ve calculated your income, applied DTI ratios, translated your payment ceiling into a loan amount, accounted for down payment and closing costs, and assessed your credit position. Now it’s time to match your profile to the loan program that gives you the best combination of rate, flexibility, and long-term cost. A comprehensive overview of types of home loans available in Virginia can help you compare your options side by side before committing.
Loan Program Decision Matrix:
Conventional | Best for: Strong credit, 5%+ down, stable W-2 income | Min credit: 620 | Down payment: 3–20%+ | DTI limit: 45–50% | Key advantage: No upfront MIP; PMI drops at 20% equity
FHA | Best for: Lower credit scores, first-time buyers, higher DTI | Min credit: 500 | Down payment: 3.5–10% | DTI limit: 43–57% with AUS | Key advantage: Flexible qualifying standards, low down payment
VA | Best for: Veterans, active duty, surviving spouses | Min credit: 580 (practical floor) | Down payment: 0% | DTI limit: 41%+ with residual income | Key advantage: No PMI, no down payment, competitive rates
USDA | Best for: Buyers in eligible rural/suburban Virginia areas | Min credit: 640 | Down payment: 0% | DTI limit: 41%+ with AUS | Key advantage: No PMI, no down payment, eligible VA counties
Jumbo | Best for: High-value homes above $806,500 | Min credit: 680+ | Down payment: 10–20%+ | DTI limit: 43% | Key advantage: Covers high-price markets where conforming limits don’t reach
Bank Statement / Non-QM | Best for: Self-employed borrowers, complex income | Min credit: 620+ | Down payment: 10–20%+ | DTI limit: Varies by program | Key advantage: Uses bank deposits instead of tax returns
The Broker Advantage in Rate Shopping: When you apply directly through a retail lender — Rocket Mortgage, Movement Mortgage, PrimeLending, or any single-lender institution — you receive that lender’s product offerings and their pricing. That’s one set of options.
A mortgage broker shops hundreds of lenders simultaneously. That means competing offers, negotiated terms, and the ability to match your specific profile to the lender who prices it most competitively. For borrowers with non-standard income, credit challenges, or unique property types, this breadth of access is often the difference between qualifying and not qualifying — or between a good rate and a great one. See how a local mortgage broker compares to an online lender when it comes to pricing and service.
Pre-Qualification vs. Pre-Approval: Pre-qualification is an estimate based on stated information and a soft pull — no credit impact, quick to obtain, useful for early planning. Pre-approval is a verified assessment based on documented income, assets, and a hard pull credit inquiry. Pre-approval carries weight with sellers and real estate agents because it reflects actual underwriting review, not just a surface-level estimate.
What Pre-Approval Requires: Recent pay stubs and W-2s (or two years of tax returns for self-employed), bank and asset statements, government-issued ID, and employment history for the past two years.

Your Affordability Number Is Calculable — Here’s What to Do With It
Let’s bring it together. You now have a framework that takes you from gross income to loan program in six concrete steps. Here’s a quick reference checklist:
1. Calculate gross monthly income — use pre-tax figures; average two years for self-employed
2. Apply DTI limits — identify your front-end and back-end ceilings by loan type
3. Back into your loan amount — use the payment factor table with current rate scenarios
4. Account for cash to close — down payment, closing costs (2–4% in Virginia), and reserves
5. Assess your credit position — use a soft pull to explore without impacting your score
6. Match your profile to the right loan program — and get pre-approved with documented verification
The math in this guide is designed to give you a real working number — not a range so wide it’s meaningless, and not an inflated figure that sets you up for disappointment when you sit down with a lender.
