What's included in /property
Full amortization schedule
Exact monthly payment, principal, interest, and remaining balance for every month of a loan, not just a summary.
Mortgage affordability
How much you can actually borrow given income, debts, and down payment — using standard DTI rules.
Tax and closing costs
Stamp duty, capital gains tax, and closing costs calculated per-country, not a generic global formula.
Neighborhood scoring
Weighted composite score across 8 factors, adjustable by buyer profile (family, investor, retiree, young professional).
Rent vs. buy analysis
Total-cost-of-ownership comparison, not just a monthly payment comparison.

Frequently asked questions
Does this include live property listings?
No. This namespace provides calculators and reference data, not an MLS feed — licensing live listing data has different legal terms per country.
How current is the stamp duty / tax data?
Reviewed annually. Reference rates are tax-code data, which changes far less often than market data.
Can I get the full month-by-month schedule?
Yes — pass full_schedule=true on /amortization for every month's principal, interest, and balance.
