How Much House Can a First-Time Buyer Afford?

Last updated:

The home price you can afford depends on more than your salary. Lenders weigh debt ratios, down payment, credit score, and the local cost of taxes and insurance. Below is the same framework experienced buyers use to find a number they can actually live with.

Start with your monthly budget, not the home price

Decide how much you can comfortably spend each month on housing before you talk to a lender. Add up your take-home pay, subtract real monthly expenses including retirement savings and groceries, and see what is left. A comfortable mortgage payment is one that still lets you save, handle a surprise car repair, and enjoy life.

Understand the 28/36 rule

The 28/36 rule says housing costs should stay below 28% of gross monthly income and total debt payments should stay below 36%. Housing costs - principal, interest, property taxes, homeowners insurance, and any HOA dues - are collectively called PITI. Many lenders will approve total debt ratios up to 43% or even 50%, but approval and affordability are not the same thing.

Know what really goes into the monthly payment

The listing price tells only part of the story. Every month a homeowner owes:

  • Principal and interest on the loan.
  • Property taxes, which vary dramatically by state and county.
  • Homeowners insurance, which has risen sharply in many markets.
  • Private mortgage insurance (PMI) if the down payment is less than 20% on a conventional loan.
  • HOA or condo fees, which can range from $0 to more than $1,000 per month.

Compare homes on the all-in PITI number, not just principal and interest.

Down payment, closing costs, and reserves

A 20% down payment is not required. FHA loans allow 3.5% down. Many conventional loans for first-time buyers allow 3% down. VA and USDA loans require no down payment for eligible buyers. Closing costs typically run 2% to 5% of the loan amount, and most lenders want to see two months of mortgage payments in reserves after closing.

How interest rates change what you can afford

Small rate changes have big consequences. On a $350,000 loan, dropping from 7.0% to 6.0% lowers the monthly principal and interest payment by about $225 - roughly $80,000 over the life of a 30-year loan. Shopping at least three lenders and improving your credit score before applying often pays off more than chasing a slightly cheaper home.

Leave room for the cost of owning, not just buying

Set aside 1% to 3% of the home's value each year for maintenance, repairs, and larger projects like a roof or HVAC system. Buying a home that consumes every dollar of monthly capacity leaves no margin for these realities.

Frequently asked questions

The 28/36 rule is an affordability guideline that says you should spend no more than 28% of your gross monthly income on total housing costs (PITI) and no more than 36% on all monthly debt payments combined. It is a conservative benchmark used by lenders and financial planners to keep buyers from becoming house-poor.
