RentCast Property Records Search

Use this endpoint when you need to search across multiple property records using flexible filters like location radius, bedroom/bathroom counts, property type, or square footage ranges. Prefer this over the Property By ID endpoint when you don't have a specific property ID and need to discover or enumerate properties matching certain criteria. Ideal for market research, neighborhood analysis, lead generation, or building property datasets.

• No properties found matching the filters — returns empty data array
• Invalid state abbreviation — returns 400 validation error
• Radius exceeds 100 miles — returns 400 bad request
• Limit outside 1-500 range — returns 400 validation error
• Missing both address and location parameters — may return 400 or empty results
• Malformed range syntax for bedrooms/bathrooms/squareFootage — returns 400 error
• Rate limit or payment failure — returns 402 or 429 error
