Frequently asked questions

Is 20% down required?

No — many programs allow far less (FHA from 3.5%, some conventional from 3%) — but below 20% usually means paying PMI.

What does PMI cost?

Commonly around 0.3–1.5% of the loan per year, depending on credit and LTV, added to your monthly payment.

Should I put more down?

More down means smaller payments and less interest, but weigh it against keeping an emergency fund.
