Search RentCast's property records database — the underlying county/MLS-sourced record for real US homes (NOT active listings; use list_active_listings for what's for sale/rent). Filter by a single address, or by a city+state, a zip code, or a lat/long + radius, then narrow with propertyType, bedrooms, bathrooms, or square footage. Returns a summarized list of matching properties (id, address, type, beds/baths, square footage, year built, last sale). Use the returned id or address with get_property_details for full attributes. Bedrooms/bathrooms/squareFootage accept an exact value ('3'), a range ('3-5'), or a list ('2,3,4'). Prices are USD; square footage is in square feet.

Fetch the FULL record for a single property — all structural attributes (type, beds, baths, square footage, lot size, year built), features, tax assessments and amounts, last sale price/date, and owner info where available. Look a property up either by its RentCast id (from search_properties) or directly by address. Use this after search_properties to drill into one property, or on its own when you already have the exact address. Returns the complete record as JSON; prices are USD, areas are in square feet. This is a property RECORD, not a for-sale/rent listing.

Estimate the fair-market LONG-TERM monthly rent for a property using RentCast's AVM (automated valuation model). Give an address, or a lat/long. For the sharpest estimate, also pass the property's propertyType, bedrooms, bathrooms, and squareFootage — or set lookup_subject_attributes=true to have RentCast look those up automatically before estimating. Returns the point rent estimate plus a low–high range (all USD per month) and the top comparable rentals the model used (address, rent, beds/baths, square footage, distance in miles). This is the core valuation tool — pair it with get_market_stats to compare an estimate against the zip-code average, or call it per-listing to rank rental opportunities.

Estimate the current SALE (market) value of a property using RentCast's AVM. This is the sale-price counterpart to get_rent_estimate. Give an address or a lat/long; optionally pass the subject's propertyType, bedrooms, bathrooms, and squareFootage, or set lookup_subject_attributes=true to have RentCast fill them in. Returns the point value estimate plus a low–high range (all USD) and the top comparable SALES the model used (address, price, beds/baths, square footage, distance in miles). Use to gauge what a property is worth, to compute a rent-to-value / gross-yield ratio alongside get_rent_estimate, or to sanity-check a list price.

Get aggregate market statistics and trends for a ZIP CODE — average and median sale price, average and median rent, price/rent per square foot, average days on market, and listing counts. Use this to establish the local baseline: e.g. compare a single property's get_rent_estimate against the zip's average rent, or gauge whether an area is hot (low days-on-market, many new listings). Choose data_type to get sale stats, rental stats, or both. All prices are USD; rents are USD/month. Returns a summarized snapshot; if RentCast has too little data for a zip, the corresponding sale or rental block is omitted.

List CURRENTLY ACTIVE sale or rental listings for an area — the real, on-market inventory (unlike search_properties, which searches historical property records). Set listing_type to 'sale' or 'rental' to choose the market. Scope by city+state and/or zip code, and filter by bedrooms, bathrooms, and property type. Returns a summarized list (id, address, price, beds/baths, square footage, days on market, status), most recently seen first. Prices are USD (a total sale price for 'sale', a monthly rent for 'rental'). NOTE: RentCast does not filter by price server-side — request the listings, then filter/rank by the returned price yourself. This is the entry point for workflows like 'find 3-bed listings in under $X, then estimate rent for each' — feed each result's address to get_rent_estimate.
