How Much House Can I Afford in 2026?
With rates still elevated, the math of home affordability has shifted significantly. Here's exactly how to calculate what you can comfortably buy — and what most buyers get wrong.
The question "how much house can I afford?" has two answers: what the bank will lend you, and what you should actually spend. Those numbers are not the same — and confusing them is one of the most expensive mistakes first-time buyers make.
This guide covers the rules lenders use, how to stress-test your own budget, and the hidden costs that catch buyers off-guard every year.
The 28/36 Rule: The Foundation
The most widely used affordability guideline is the 28/36 rule:
- 28%: Your monthly housing costs (mortgage principal + interest + property tax + homeowner's insurance, collectively called PITI) should not exceed 28% of your gross monthly income.
- 36%: Your total monthly debt payments — housing + car loans + student loans + credit cards + any other recurring debt — should not exceed 36% of gross monthly income.
If these two rules give different limits, use the lower number.
A Real-World Example
What Lenders Actually Approve
The 28/36 rule is a guideline, not a hard limit. Lenders have different standards:
- Conventional loans: Typically allow up to 43–45% total DTI. Some automated systems approve up to 50% DTI for strong borrowers (high credit score, large down payment, cash reserves).
- FHA loans: Allow up to 57% DTI in some cases. FHA is more forgiving on credit too (580+ for 3.5% down).
- VA loans: No strict DTI cap, but 41% is preferred. VA lenders look at residual income after debts and housing.
Just because a lender approves you for $450,000 doesn't mean you should spend $450,000. Pre-approval is the ceiling, not the target.
Down Payment: The Multiplier Effect
Your down payment dramatically changes your buying power. Here's how the same $2,000/month housing budget translates to home prices at 7% over 30 years:
| Down Payment | Amount | Max Home Price* | PMI? |
|---|---|---|---|
| 3% | $9,000 on $300K | ~$265,000 | Yes |
| 5% | $15,000 on $300K | ~$272,000 | Yes |
| 10% | $30,000 on $300K | ~$285,000 | Yes |
| 20% | $60,000 on $300K | ~$310,000 | No |
| 25% | $75,000 on $300K | ~$320,000 | No |
*Approximate, assuming PITI budget of $2,000/month, 1.1% annual tax, $150/mo insurance.
The Hidden Costs That Surprise First-Time Buyers
Beyond the mortgage payment, budget for these:
Closing Costs (2–5% of loan amount)
On a $300,000 loan: $6,000–$15,000 due at closing. Includes origination fees, title insurance, appraisal, attorney fees, and prepaid taxes/insurance. Many buyers are shocked when the "down payment" isn't their only upfront cost.
Property Taxes (0.5–2.5% of value per year)
National average: ~1.1% of home value per year. On a $350,000 home: $3,850/year ($321/month). But in New Jersey (2.4%) or Illinois (2.1%), that same home costs $8,400/year ($700/month) in taxes alone.
Homeowner's Insurance ($1,000–$3,500/year)
Required by lenders. Flood or earthquake insurance (often not included in standard policies) is extra — sometimes $1,500–$5,000/year in high-risk areas.
PMI (0.5–1.5% of loan per year)
Private mortgage insurance is required when your down payment is under 20%. On a $280,000 loan at 1%: $2,800/year ($233/month). This can be cancelled once you reach 20% equity.
Maintenance (1–2% of value per year)
Budget $3,000–$6,000 per year on a $300,000 home. New homes have lower maintenance in early years; older homes (especially 30–50+ years old) often need major systems (HVAC, roof, plumbing) replaced within the first 5–10 years of ownership.
The Right Question: What's Your Comfortable Payment?
Start with your take-home pay, not gross income. After your mortgage payment, you should still have comfortable room for:
- Groceries, utilities, transportation
- Childcare (if applicable — often $1,500–$3,500/month)
- Retirement savings (at minimum: get your employer match)
- Emergency fund replenishment
- Home maintenance reserve
If the mortgage payment leaves no room for any of that, the house is too expensive — regardless of what the bank approved.
