How Much House Can I Afford? Complete Home Buying Guide for 2026
Buying a home is one of the biggest financial decisions most people make. Before searching for houses, it is important to understand
how much home you can realistically afford.
The affordability of a home depends on several factors including income, debt, down payment, credit score, interest rates, property taxes,
insurance, and loan term.
The 28/36 Rule
Many lenders use the 28/36 rule when reviewing mortgage applications.
Housing expenses should not exceed 28% of gross monthly income.
Total debt payments should not exceed 36% of gross monthly income.
For example, if your monthly income is $8,000:
Maximum housing expense: $2,240
Maximum total debt payments: $2,880
Factors That Affect Home Affordability
Income
Higher income generally increases borrowing capacity.
Down Payment
A larger down payment reduces loan amount and monthly payments.
Credit Score
Higher credit scores often qualify for lower mortgage rates.
Interest Rates
Even small differences in mortgage rates can significantly impact monthly payments and total interest costs.
Existing Debt
Car loans, student loans, and credit card debt reduce mortgage qualification amounts.
Mortgage Example
Home Price: $400,000
Down Payment: $80,000
Loan Amount: $320,000
