#real-estate

How house prices are moving across the world's economies, read live from the Bank for International Settlements' Selected Residential Property Prices dataset. For roughly 60 countries the BIS publishes a quarterly residential property price index — both nominal and real (inflation-adjusted) — together with its year-on-year change. The latest endpoint returns every country's most recent reading at once — the nominal and real index plus the nominal and real year-on-year growth — sortable by nominal or real YoY so you instantly see which housing markets are heating up and which are cooling once you strip out inflation. The country endpoint returns a single country's latest reading; the history endpoint returns its quarterly index time series (nominal and real) so you can chart a market over time. Countries are given as ISO-2 codes (US, DE, GB, JP) or common names (xm is the euro area). The nominal index is the headline price level; the real index is deflated by consumer prices, so a negative real YoY means prices are falling after inflation even when the nominal index still rises. This is the real-estate / property-price macro data-cut — distinct from the FX-rate, central-bank, yield-curve, commodity and equity-index APIs in the catalogue. Live source, no key required upstream, nothing stored.

Real-estate investment maths as an API, computed locally and deterministically — the property-analysis layer a loan calculator leaves out. The cap-rate endpoint gives the net operating income and capitalization rate of a rental from its price, gross rent, vacancy allowance and operating expenses (NOI = gross rent × (1 − vacancy) − expenses; cap rate = NOI / price), plus the gross rent multiplier — the unlevered view a buyer compares deals on. The cash-flow endpoint adds financing: from a down payment (amount or percent), interest rate and term it amortizes the mortgage, then returns the monthly payment, annual debt service, the property cash flow, the cash-on-cash return (annual cash flow ÷ cash invested), the debt-service-coverage ratio (DSCR = NOI ÷ debt service, the figure lenders underwrite to) and the loan-to-value. The metrics endpoint runs the quick screening ratios investors filter on — the 1 % rule (monthly rent ≥ 1 % of price), gross rental yield, gross rent multiplier and price per square foot. Money in, ratios out, in one consistent currency. Everything is computed locally and deterministically, so it is instant and private. Ideal for proptech, real-estate-investment, rental-analysis and landlord app developers, deal-screening and underwriting tools, and personal-finance dashboards. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 compute endpoints. This is property-investment analysis; for pure loan amortization use a loan API and for DCF/NPV use an investment-appraisal API.
