How much house can I afford on my salary?

As a starting point, many lenders look for a housing payment around 28% of gross monthly income, with total debt (including housing) under 36–43%. Your actual number depends on your down payment, credit score, and the loan program you use.

Is a home affordability calculator accurate?

A calculator gives a reasonable estimate, but it can't account for your specific credit profile, debt structure, or documentation type. A pre-approval with an Atlantic Bay Mortgage Banker gives you a verified number.

Does a bigger down payment always mean I can afford more house?

Not necessarily. A larger down payment lowers your monthly payment and may remove mortgage insurance, but your qualifying income and debt ratios still set the ceiling on loan size.

What debts count against my affordability?

Car payments, student loans, credit card minimums, personal loans, and child support or alimony are typically counted. Utilities, groceries, and other living expenses aren't part of the DTI calculation, but lenders expect you to budget for them separately.

Can I afford a home if I'm self-employed?

Yes, self-employed borrowers can qualify using net income after business deductions, verified through tax returns. This often results in a lower qualifying income than gross revenue would suggest, which can affect your affordable price range.

How does my credit score affect how much house I can afford?

Your score affects your interest rate. A lower rate reduces your monthly payment, which can increase the loan amount you qualify for at the same payment level.

What's the difference between pre-qualification and knowing what I can afford?

Pre-qualification is a quick, estimate-based check. A full pre-approval verifies income, debt, and credit, giving you a real number you can shop with.

What determines affordability

Home affordability isn't calculated based on a single number. Four factors interact:

Gross monthly income: the starting point for every ratio a lender runs
Monthly debt obligations: car payments, student loans, credit cards, child support
Down payment amount: affects loan size, monthly payment, and whether you carry mortgage insurance
Credit score: shapes your interest rate, which shapes your monthly payment, which shapes what you qualify for

Two households with identical income can qualify for very different loan amounts once debt and credit are factored in. Learn how much mortgage you can afford.

The 28/36 rule

Most Conventional guidelines start with two ratios:

Ratio	What it measures	Typical limit
Front-end (housing) ratio	Monthly housing payment ÷ gross monthly income	~28%
Back-end (total debt) ratio	All monthly debt payments (including housing) ÷ gross monthly income	~36–43%, higher with strong compensating factors

Federal Housing Administration (FHA) loans often allow back-end ratios up into the low-50s with strong credit and reserves. Department of Veterans Affairs (VA) loans don't enforce a hard debt-to-income (DTI) ceiling but weigh residual income heavily. This is why the "right" affordability number depends on which loan program you're using, and not solely your income.

Unfamiliar with terms like DTI? Here's a quick breakdown of mortgage acronyms.

Income & employment documentation

Lenders need to verify income is stable and likely to continue. Standard documentation includes:

Two years of W-2s or tax returns
Recent pay stubs (typically 30 days)
Two months of bank statements
Additional documentation for bonus, commission, or self-employment income

Self-employed or 1099 borrowers are evaluated on net income after deductions, and not gross revenue, which often means a lower qualifying income than what shows on a bank statement.

Down payment & its effect on affordability

Your downpayment affects affordability in three ways:

1
Loan size: a larger down payment reduces the amount financed and the monthly payment. Using gift funds? Here's what you need to know about down payment gifts.
2
Mortgage insurance: Conventional loans under 20% down carry private mortgage insurance (PMI); FHA loans carry mortgage insurance premium (MIP) regardless of down payment size.
3
Interest rate: some pricing tiers improve as loan-to-value (LTV) decreases.

Down payment	Loan type fit	Mortgage insurance
0%	VA (eligible borrowers), USDA (eligible areas)	None (VA), guarantee fee (USDA)
3–3.5%	Conventional (3% min), FHA (3.5% min)	Required
20%+	Conventional	None

There's so much more to down payments. Here are four common down payment myths answered.

Credit score impact

Credit scores determine more than just approval. They also determine your rate, and rate determines how much house fits your budget.

i
Higher credit scores generally unlock better pricing tiers on Conventional loans.
i
FHA loans allow lower minimum scores than Conventional financing.
i
A rate difference of even half a percentage point can shift your affordable price range by tens of thousands of dollars over a 30-year term.

Affordability by loan type

Loan type	Min down payment	Typical max back-end DTI	Best fit for
Conventional	3%	45–50% w/ strong credit	Solid credit and some savings
FHA	3.5%	~50% w/ compensating factors	Lower credit scores, smaller down payments
VA	0%	No hard cap; residual income reviewed	Eligible veterans and service members
Jumbo	Varies by lender	Typically 43–45%	Loan amounts above the conforming limit
