A verified address isn't a qualified lead.
AddressVerify validates the residential address, then tells you the exact property type and estimated value behind it, so you only pay for the leads that actually fit.

Residential Address Verification
Our API validates residential addresses in real-time, filtering out non-residential and fake addresses, correcting errors, and standardizing formats. This improves lead data quality, ensuring accurate targeting for lead generation, lead buying, and data enrichment.

Classify & Enrich Properties
Our API classifies residential properties into 7 distinct types: Single-Family, Multi-Family, Condo, Townhouse, Apartment, Manufactured/Mobile Home, and Lot. Unlike providers that lump mobile homes in with single-family, we return them as their own type, so a "single-family only" filter actually holds. Each result is enriched with bedrooms, bathrooms, square footage, year built, and lot size.
- 7 distinct property types
- Separates mobile/manufactured from single-family
- Property details: beds, baths, sqft, lot size
- Accurate buy-box filtering
Home Value & Market Insights
Get current estimated home values, tax assessment data, and real-time listing status for every address. Identify high-value prospects, track market activity, and score leads by financial profile, all included on every plan at no extra cost.
- Current estimated home values
- Tax assessed values & assessment year
- Listing status & sale history
- Value-based lead scoring
14 Sycamore Ln, Ada, OK 74820
"homeType": "SINGLE_FAMILY"
Looks like a lead you'd buy. It isn't.
"homeType": "MANUFACTURED"
A mobile home. Skip it, or price it right.
One address. Two very different answers.
Anyone can confirm a good address. The value is in correctly flagging the ones you shouldn't pay for. Roughly 1 in 16 addresses is a manufactured or mobile home that many APIs quietly return as single-family.
If your API can't tell the difference, your “single-family only” filter is leaking spend on leads you can't close. AddressVerify returns the exact property type, so your buy-box actually holds.
