# Certihomes — llms.txt > Certihomes is a real-estate portal for the US that ranks every listing by True Lifestyle Cost (TLC) — the full monthly cost of owning the home (mortgage, taxes, insurance, HOA, utilities, commute), not just the list price. The site is server-rendered Next.js and exposes machine-readable JSON-LD (`RealEstateListing`, `ItemList`, `RealEstateAgent`) on every page. AI agents are welcome to crawl the site. ## Key endpoints - `https://portal.certihomes.com/` — landing page with featured listings - `https://portal.certihomes.com/search?q=&beds=&minPrice=&maxPrice=&city=` — search UI - `https://portal.certihomes.com/listing/` — listing detail (HTML + JSON-LD) - `https://portal.certihomes.com/api/listings/search?...` — JSON search API (no auth, public listings) - `https://portal.certihomes.com/api/listings/` — JSON listing detail - `https://portal.certihomes.com/sitemap.xml` — sitemap ## True Lifestyle Cost (TLC) For each listing the page reports a TLC monthly figure with this breakdown: - mortgage (P&I), property tax, home insurance, HOA, utilities estimate (+ optional commute when signed in) ## Asking questions To answer "is this home affordable for X budget?" or "find me 3BR under 600k in city Y", call: `GET /api/listings/search?q=&beds=3&maxPrice=600000` …and read the `items[].price`, `items[].beds`, `items[].url`. The TLC is computed client-side from the price and tax fields. Last updated: 2026-05-16
