You see a home listed for $350,000. The online calculator says you can afford it. But then the real numbers come: property taxes, homeowners insurance, PMI, HOA fees. Suddenly your monthly payment is $600 higher than expected.
This guide gives you the real formula to determine how much house you can afford in 2026 – no fluff, no lender sugarcoating.
The 28/36 Rule – Still the Gold Standard
Lenders use two ratios:
- Front‑end ratio (housing) : Monthly housing costs (PITI – principal, interest, taxes, insurance) ÷ gross monthly income ≤ 28%
- Back‑end ratio (total debt) : Housing + all other debt (car, student, credit cards) ÷ gross monthly income ≤ 36%
Example – $80,000 income ($6,667/month gross):
- Max housing payment: $1,867 (28%)
- Max total debt: $2,400 (36%)
If you have a $400 car payment and $200 student loan, your remaining allowed housing payment = $2,400 – $600 = $1,800. Slightly less than $1,867.
How Much Home Does That Housing Payment Buy?
At 6.2% interest, 5% down, 1.2% property tax, $1,500 annual insurance:
| Monthly PITI | Approx Home Price |
|---|---|
| $1,500 | $225,000 |
| $1,800 | $270,000 |
| $2,000 | $300,000 |
| $2,500 | $375,000 |
| $3,000 | $450,000 |
So with $80k income, max PITI of $1,867 buys roughly a $280,000 home.
Factors That Increase or Decrease Affordability
Increases buying power:
- Larger down payment (20% eliminates PMI, lowers payment)
- Lower property tax state (e.g., Alabama 0.4% vs Texas 2.2%)
- No other debt (back‑end ratio = front‑end ratio)
Decreases buying power:
PMI (adds 0.5‑1% of loan amount annually)
High HOA fees ($300/month reduces buying power by ~$50,000)
High insurance (Florida, California wildfire zones)
The 2026 Affordability Crisis – By the Numbers
ThesCompared to 2021:
- Home prices up 35%
- Mortgage rates up 120% (3% to 6.6%)
- Monthly payment on median home up 110%
Example – Median US home $410,000 in 2026:
- 2021: 3% rate, 5% down → $1,750/month
- 2026: 6.2% rate, 5% down → $2,950/month
You now need $115,000 household income to afford the same home that required $65,000 in 2021.
