How Much House Can I Afford?Income, Debt & Payment Guide
If you are asking how much house can I afford, the answer comes from three numbers: your gross income, your monthly debts, and how large a payment you are comfortable sustaining. This guide explains how lenders measure affordability, walks through the 28/36 rule and debt-to-income limits, and shows real payment and price examples so you can shop with confidence.

The Short Answer
How Much House Can I Afford? Here Is the Framework
When you ask how much house can I afford, the honest answer is that a lender is really calculating a monthly payment you can carry — and working backward from that payment to a purchase price. Most conventional guidance suggests keeping housing costs at roughly 28% of gross monthly income and total debt at roughly 36%, but real approvals depend on the specific loan program's debt-to-income limits, your documented income, your credit profile, and your cash reserves.
The number you can borrow is rarely the number you should borrow. The goal of this guide is to help you find the price that matches both the lender's guidelines and your own comfort level — so the payment still works if your income dips, your taxes rise, or rates change when you refinance.

How Lenders Look at Income
The Three Numbers That Decide How Much House You Can Afford
Almost every affordability calculation comes down to income, obligations, and liquidity. If any one of these is unsteady — a recent job change, a new vehicle loan, a small savings balance — the realistic price range changes with it.
Review My NumbersIncome the lender will count
Lenders review gross monthly income before taxes. W-2 salary is straightforward; overtime, bonus, and commission generally need roughly a two-year documented history and a reasonable expectation of continuation. Self-employed borrowers are usually evaluated from tax returns or, for qualifying programs, bank statement or P&L documentation.
The debts that reduce your buying power
Car loans, student loans, personal loans, credit card minimums, and court-ordered obligations all count toward your debt-to-income ratio. Even estimated obligations such as deferred student loan payments can be included by some lenders.
Your cash position and reserves
The purchase needs a down payment, closing costs, and often at least two months of mortgage payments in reserves. A comfortable cash position can strengthen a file, while a thin one can narrow the price range that makes sense.

Debt-to-Income
The 28/36 Rule and Debt-to-Income Limits
The 28/36 rule is a popular way to estimate affordability. It suggests that a housing payment (principal, interest, taxes, insurance, and any HOA dues) stay under 28% of gross monthly income — the front-end ratio — and that all monthly debts together stay under 36% — the back-end ratio. It is a useful discipline, but you should know where it comes from.
The 28/36 thresholds are modeled on the housing and total-debt limits historically associated with FHA guidance. Actual approvals today are driven by automated underwriting findings and each program's own debt-to-income rules, which range from below 36% to somewhat above 50% depending on the loan type and your compensating factors. The table below summarizes the typical landscape.
Ranges are common guidelines for illustration and change frequently. Final approval, including any exception, depends on the lender's current guidelines, investor requirements, and your complete file.
Key takeaway: the 28/36 rule is a planning tool, not a rule lenders are required to follow. A lender may approve a higher ratio when you show compensating factors such as substantial reserves or a long, stable employment history — and may decline a lower ratio when the file is otherwise weak. Always confirm the limit that applies to your specific program.

How to Read the Table
- Housing budget is 28% of gross monthly income — it covers principal, interest, taxes, insurance, and HOA dues.
- Room for other debt is the remaining 8% under a 36% total-debt ceiling. If your car or student loans exceed it, the housing budget shrinks.
- The price range translates that payment at an illustrative rate; a higher rate lowers the price, a lower rate raises it.
- Cash to close covers the 10% down payment plus typical closing costs. Usable reserves for cushioning the file are additional.

Monthly Payment Anatomy
What Your Monthly Payment Is Actually Made Of
The number you can afford is a full monthly payment — not just principal and interest. Lenders look at the complete obligation, and so should you, because two homes at the same price can carry very different payments once taxes, insurance, and HOA dues are added.
Principal & interest
Largest pieceThe loan payment itself, set by the loan amount, interest rate, and term. This is the part that changes most when rates move or your credit score shifts.
Property taxes
Paid monthlyProperty taxes are usually collected monthly in escrow. They are a meaningful part of the payment in many California counties, so never compare homes on principal and interest alone.
Homeowners insurance
Paid monthlyRequired on nearly every mortgage. In some regions, additional hazard insurance may also apply.
Mortgage insurance & HOA
If applicableFHA loans carry mortgage insurance premiums; conventional loans may carry PMI below 20% down. Condos and planned communities add HOA dues, which lenders count in your housing ratio.
Comparing Monthly Payments at Three Price Points
The example assumes a 10% down payment, a 30-year fixed loan at an illustrative 6.5% rate, an annual property tax of 1.25%, and homeowners insurance of 0.5% of the price. No HOA or mortgage insurance is included.

Cash to Close
Down Payment and Cash to Close
The down payment changes the loan amount and the monthly payment — and on conventional loans, reaching 20% often removes private mortgage insurance. But the down payment is not the only cash you need. Closing costs typically run about 2%–5% of the loan amount, and many programs prefer 1–2 months of reserves.

Credit & Loan Programs
How Credit and Loan Choice Change Your Price Ceiling
Your credit score does not set your debt ratio — it sets your rate. But a lower rate means more principal and interest room inside the same monthly payment, which can meaningfully increase the price you can afford. Loan program flexibility also affects how much of your income counts.
Conventional & first-time buyers
Conventional financing rewards stronger credit with better pricing. Low-down programs can help eligible buyers with as little as 3% down, and 3% down conventional options are worth reviewing if your credit and income are solid.
FHA & VA financing
FHA guidelines accept lower credit scores and more flexible debt ratios in many scenarios. VA loans offer 0% down for eligible veterans and service members, with flexible credit and residual-income guidelines.
Jumbo & higher-value homes
If your target price is above the conforming loan limit, jumbo financing can support higher purchase prices. Many programs allow 10%–20% down; lender requirements and reserves vary.
Self-employed & non-QM
Business owners with tax write-offs often qualify using bank statement, P&L, or asset-depletion documentation when tax returns understate true income. These programs can raise buying power.
Looking for more capacity? If your credit is in progress or your income documentation is complex, ask about interest-only programs, co-borrower options, and down payment assistance. Bring us any other lender's offer — we will likely beat it.
Practical Steps
How to Afford More House — Carefully
01Pay down high-balance debts
A car loan or credit card minimum that gets paid off frees up debt-ratio room. Clearing a $200 monthly payment can free up roughly $200 of monthly housing capacity on the same ratio.
02Improve your credit score before applying
Checking your reports, paying on time, and reducing utilization can lower the rate offered — and a lower rate stretches the same payment further.
03Document income carefully
Overtime, bonus, commission, and self-employment income are eligible when properly evidenced. Lenders may only count recent bonus history for a period, so provide clear records and ask how income will be calculated before you buy.
04Explore assistance and co-borrowers
Down payment assistance, non-occupant co-borrowers, and gift funds can bridge a cash gap. Depending on the program, a co-borrower's income may also be considered in qualifying.
05Compare programs, not just rates
FHA, VA, and non-QM programs price and qualify differently. The same borrower can have a meaningfully different price ceiling depending on the loan program chosen.
The most important step: how much house you can afford changes with your file. A short conversation with a licensed loan officer will give you a real number — including the payment, the price range, and the program that fits — instead of a rough estimate.Start your application.
Frequently Asked Questions
How much house can I afford on a $100,000 salary?
With the 28/36 rule, a $100,000 annual income (about $8,333 per month) points to a housing payment of roughly $2,330 per month. With typical debts under $670 per month and a 10% down payment, that payment range often supports a purchase price in the mid $300,000s, depending on current rates, taxes, insurance, and lender guidelines. A licensed loan officer can run the exact scenario for your file.
Does the 28/36 rule apply to every loan program?
No. The 28/36 rule is a common yardstick, not a universal rule. It is modeled on the housing and total-debt thresholds historically used within FHA guidance (28% for housing, 36% for total debt), but FHA, VA, conventional, jumbo, and non-QM programs each have their own front-end and back-end DTI limits.
Do overtime, bonus, and commission income count?
They can — generally when they have a documented history of about two years and look likely to continue. Lenders usually average this income or use the lower of the recent years. If your earnings are new or inconsistent, the lender may only count a portion, so ask how your specific income will be calculated before you shop.
Should I use the maximum pre-approval amount?
Not necessarily. A pre-approval reflects what a lender may allow, not what fits comfortably in your life. Add in taxes, utilities, HOA dues, maintenance, and savings goals, then choose a payment you can sustain through a job change or a rate renewal.
How much down payment do I need?
It depends on the program. Conventional loans may allow as little as 3% or 3.5% for qualifying buyers, FHA loans commonly allow 3.5% with a qualifying credit profile, and VA loans may allow 0% down for eligible veterans. Larger down payments reduce the loan amount and can lower certain costs.
Can I be approved with a high debt-to-income ratio?
Sometimes. FHA allows back-end DTI up to 43% in many cases, and up to 50% or somewhat above with documented compensating factors such as strong reserves or a lengthy employment history. Conventional and jumbo guidelines are generally stricter. Nothing is guaranteed until a lender reviews your complete file.
Does my credit score change how much house I can afford?
Yes, indirectly. Your score affects the interest rate offered, and the rate affects the monthly principal and interest payment. A higher score typically supports a lower rate and therefore a larger affordable purchase price at the same monthly payment.
