How Much House Can I Afford? The Complete 2026 Guide

Published: June 2026 | Reading time: 4 minutes

"How much house can I afford?" is the first question every home buyer asks — and the answer depends on more than just your salary. Here's exactly how lenders calculate it, and a free tool to get your number instantly.

The 28/36 Rule: How Lenders Think

Most lenders follow the 28/36 rule:

Example: If you earn $100,000/year ($8,333/month):
Max housing payment = $8,333 × 28% = $2,333
Max total debt = $8,333 × 36% = $3,000
If you pay $500/month in car/student loans, your housing budget drops to $2,500.

Income → Home Price: The Real Math

$50,000$1,167~$175,000
$75,000$1,750~$265,000
$100,000$2,333~$355,000
$150,000$3,500~$535,000
$200,000$4,667~$715,000

5 Factors That Change Your Number

1. Down Payment Size

A 20% down payment eliminates PMI and lowers your monthly payment. But with 3% down conventional or 3.5% FHA, you can buy sooner — just expect to pay mortgage insurance.

2. Interest Rate

In 2026, rates hover around 6–7%. A 1% rate difference on a $300,000 loan changes your monthly payment by ~$190. Shop at least 3 lenders.

3. Property Taxes

Taxes vary dramatically: 0.5% in Alabama vs. 2.5% in New Jersey. A $400,000 home in a high-tax state costs $800/month more than the same home in a low-tax state.

4. Existing Debt

Car loans, student loans, and credit card minimums eat into your DTI. Paying off a $400/month car loan frees up ~$65,000 in buying power.

5. HOA Fees

A $500/month HOA reduces your maximum loan by ~$80,000. Always check HOA costs before making an offer.
