What this result actually means
This number is not just based on your income.
It reflects how much home you can realistically afford once you account for:
- your existing debt
- interest rates
- property taxes
- insurance and ongoing housing costs
The goal is not to find the maximum home price.
The goal is to understand what monthly payment you can carry consistently — without putting pressure on your budget.
Comfortable vs risky affordability
Your maximum number is not your target.
- Comfortable means your housing cost leaves room for saving, investing, and normal life variability.
- Stretch means the payment is manageable, but your flexibility is reduced.
- Risky means your housing cost takes too much of your monthly cash flow.
A simple rule of thumb:
- under 25% of take-home income → very comfortable
- 25–35% → manageable
- 35%+ → higher risk
Lenders use gross income.
Your life runs on net income — that’s where decisions should be made.
What impacts affordability the most
Not all inputs matter equally. These have the biggest effect:
Income
Higher income increases affordability, but stability matters more than the raw number.
Debt (DTI)
Existing debt directly reduces how much housing you can afford. Even small debts can significantly lower your price range.
Can you afford this monthly payment long-term?Interest rate
A 1% increase in rate can reduce affordability by 10–15%. You’re buying a payment, not a price.
Should you wait before buying based on market conditions?Down payment
More down lowers your loan and monthly cost, but using all your cash can create risk.
Taxes and insurance
Often underestimated. Together they can add hundreds per month and shift a deal from comfortable to tight.
Read deeper rules and common mistakes
A quick reality check example
Income: $120,000/year
Estimated home price: ~$420,000
Monthly payment: ~$3,100–$3,300
This looks reasonable based on gross income.
But after taxes, take-home might be closer to ~$7,000/month.
Now your housing cost is ~45% of your actual cash flow.
That’s still possible — but much tighter in real life.
Common mistakes
- focusing only on home price instead of monthly cost
- ignoring taxes and insurance
- using gross income instead of take-home
- stretching to the lender maximum
- spending all savings on the down payment
- underestimating maintenance (1–2% of home value annually)
What to do next
If this number feels too tight, try adjusting:
- your down payment
- your target monthly budget
- your expected interest rate
