calculate_mortgage — Full monthly housing cost for a US mortgage: principal and interest, property tax, homeowners insurance, mortgage insurance and HOA dues, plus lifetime totals and payoff timing.
calculate_pmi — Mortgage insurance for any US loan programme, including the upfront charges most calculators omit.
calculate_property_tax — Annual and monthly property tax for a home, using a state's average effective rate.
calculate_affordability — Maximum affordable home price from income, existing debt payments and available down payment, using the 28/36 qualifying ratios.
calculate_refinance — Whether refinancing is worth it: the new payment, monthly saving, and how many months it takes to recover closing costs.
estimate_closing_costs — Line-by-line buyer closing costs — lender fees, title, appraisal, transfer taxes, prepaid escrow — plus total cash needed at the table including the down payment.
calculate_rent_vs_buy — Compares renting and buying on net wealth rather than on monthly payment, accounting for equity, appreciation, maintenance, selling costs, and the return a renter earns on money not spent on a down payment.
compare_loans — Compares two to five loan scenarios and reports which is cheapest by monthly payment and which by lifetime cost, separately, because they frequently are not the same loan.
