The amount you can borrow depends on several factors: your credit score, income, existing debt obligations, and the lender's maximum loan limits. Understanding these factors before you apply helps you set realistic expectations and find the right lender.

Key Factors That Determine Your Loan Amount

The 28% Rule

Your monthly housing payment (PITI: principal, interest, taxes, insurance) should not exceed 28% of your gross monthly income.

The 36% Rule

Your total monthly debt payments (housing + all other debt) should not exceed 36% of your gross monthly income.

Down Payment

A larger down payment reduces your loan amount, monthly payment, and may eliminate PMI (required when down payment is below 20%).

Credit Score

Mortgage rates vary significantly by credit score. A 760 score may get a rate 1–2% lower than a 620 score, saving tens of thousands over the loan term.

Who Should Consider Waiting or Alternative Paths

Buying a home is the largest financial decision most people make. Consider waiting or exploring alternatives if:

  • Your debt-to-income ratio exceeds 43%: Most conventional lenders cap DTI at 43–45%. Above this, you will likely be declined or offered significantly worse terms. Paying down existing debt before applying will improve your rate and approval odds.
  • You plan to move within 3–5 years: Closing costs typically run 2–5% of the loan amount. If you sell before recouping these costs through equity appreciation, you may lose money compared to renting.
  • You have less than 3% for a down payment: While FHA loans allow 3.5% down, PMI on low-down-payment loans adds 0.5–1.5% annually to your effective rate. A larger down payment eliminates PMI and reduces your rate.
  • Your credit score is below 620: Conventional loans require 620+. FHA loans accept 580+ with 3.5% down, or 500+ with 10% down. Below 500, improving your credit before applying will save tens of thousands in interest over the loan term.

How to Maximize Your Loan Amount

Improve your credit score — Even a 20-point improvement can unlock significantly higher loan amounts and lower rates.
Pay down existing debt — Reducing your debt-to-income ratio is one of the fastest ways to qualify for more.
Add a co-signer — A co-signer with strong credit and income can dramatically increase your borrowing power.
Apply with multiple lenders — Different lenders have different underwriting criteria. Pre-qualifying with 3–4 lenders gives you the best picture of your options.

Frequently Asked Questions

How much mortgage can I afford on a $75,000 salary? +
Using the 28% rule: $75,000 / 12 = $6,250/month gross income. 28% of $6,250 = $1,750/month maximum housing payment. At current rates (~7%), that corresponds to roughly a $260,000–$280,000 mortgage.
What is the 28/36 rule for mortgages? +
The 28/36 rule states that your monthly housing costs should not exceed 28% of gross monthly income, and your total monthly debt payments should not exceed 36% of gross monthly income.
How much house can I afford with a $100,000 salary? +
Using the 28% rule: $100,000 / 12 = $8,333/month gross income. 28% = $2,333/month maximum housing payment. At 7% over 30 years, that corresponds to roughly a $350,000–$370,000 mortgage.
Does my credit score affect how much mortgage I can get? +
Yes. A higher credit score qualifies you for lower rates, which means you can afford more house for the same monthly payment. A 1% rate difference on a $300,000 mortgage saves approximately $60,000 in interest over 30 years.
What is the minimum down payment for a mortgage? +
Conventional loans: 3–5% minimum. FHA loans: 3.5% (with 580+ score). VA loans: 0% (for eligible military). USDA loans: 0% (for eligible rural areas). A 20% down payment eliminates PMI.
