FAQ
What is PMI? Private Mortgage Insurance, required when down payment is less than 20%.
How do I remove PMI? Once equity reaches 20%, request removal. Automatic cancellation at 22% equity.
Can I afford this mortgage? Use the 28/36 rule: housing costs ≤ 28% of income, total debt ≤ 36%.
What about adjustable-rate mortgages? This calculator is for fixed-rate mortgages. ARM payments can change after the initial fixed period.
How does the loan term affect total cost? Shorter terms have higher monthly payments but much less total interest.
