Frequently Asked Questions
1) What is a βsafeβ DTI target?
Many people aim for 36% total DTI. Some prefer lower (30β33%) for extra comfort.
2) Should I include taxes and insurance in the housing payment?
Yes β it usually gives the most realistic budget, because those costs are paid monthly in many loans.
3) Why does interest rate change the max home price so much?
Your monthly PI payment is heavily affected by the rate, so the same budget supports a smaller loan at higher rates.
4) Does this include closing costs?
No β this is affordability based on monthly payment. Use the Closing Costs Calculator to estimate cash-to-close.
5) Is this accurate worldwide?
The math is universal. Local rules (taxes, insurance, lending limits) vary, so treat results as a planning estimate.
