Frequently asked questions
How is the monthly payment calculated?
With the standard amortization formula: M = P·r(1+r)ⁿ/((1+r)ⁿ−1), where P is the loan amount, r the monthly rate and n the number of payments.
What is PMI and when do I pay it?
Private mortgage insurance, usually required when your down payment is under 20%. We estimate 0.5% of the loan per year — your lender sets the real figure.
Is this financial advice?
No — these are estimates for planning only. Actual payments depend on taxes, fees, insurance and lender terms. Talk to a qualified professional before borrowing.
