What happens if I add extra principal?Extra monthly principal shortens payoff and reduces interest. Use the slider to see the impact instantly.

Can I include HOA dues and PMI?Yes—enter HOA, and enable PMI when down payment is under 20% to see the true monthly cost.

How do I check affordability?Toggle the affordability panel, enter income and debts, and compare the result to your lender’s DTI target.

How to estimate your mortgage

    Add home price, down payment, APR, and loan term.

  2. Include housing costs

    Provide annual property tax, homeowners insurance, HOA fees, and PMI if needed.

  3. Test extra payments
