Kuinka laskea Home Affordability

Mikä on Home Affordability?

Home affordability calculators estimate the maximum home price based on income, debts, down payment, and rate using the 28/36 debt-to-income rule lenders apply.

Kaava

Max housing = Gross monthly income × 28%; Max total debt = Gross monthly income × 36%; Max home price ≈ Max housing × 360 months / Monthly payment factor
I
Gross annual income (Currency)
D

Usein kysytyt kysymykset

What's included in "debts"?

Car loans, student loans, credit cards, personal loans. NOT utilities, insurance, rent. The 36% rule includes all of these + new mortgage payment.

Do I need 20% down?

Not legally. But < 20% triggers PMI and higher rates. 3–5% is possible but expensive. 10–15% is a middle ground. Better credit score = access to lower rates at all down payments.

How does credit score affect affordability?

Huge. 620 credit score might get 7.5% rate; 780+ gets 5.5%. That 2% difference adds $100k+ in interest on a $400k mortgage. Raise credit score before buying.
