Question 1

What does ATTOM Property Data do?

Accepted Answer

ATTOM Property Data is a comprehensive US property data API providing residential and commercial real estate data for over 155 million US properties, including property valuations (AVMs), sales history, mortgage data, neighborhood demographics, school district ratings, hazard risk scores, and owner information. ATTOM is a leading provider to US mortgage lenders, insurtech companies, real estate investors, and proptech platforms that require deep property-level data enrichment for US real estate applications. This API is US-only and has no Nigeria property data coverage.

For Nigerian developers and companies, ATTOM Property Data is relevant in two specific contexts: Nigerian-owned or Nigerian-operated businesses serving the US real estate market, and Nigerian investment funds and diaspora investors conducting due diligence on US real estate investments. Nigeria's high-net-worth diaspora community in the United States includes significant real estate investors who purchase US investment properties — rental properties, commercial real estate, and fix-and-flip projects — and tools built for this community benefit from ATTOM's comprehensive US property data.

Property valuation (AVM) through ATTOM provides an estimated market value for any US address, along with confidence scores and comparable sales data used to justify the valuation. Nigerian investors evaluating a US property purchase and Nigerian investment fund managers conducting portfolio valuation on US holdings can use ATTOM AVM data to get rapid property value estimates without paying for a formal appraisal on every property under consideration.

Sales history data from ATTOM shows every recorded sale transaction for a US property: sale price, sale date, buyer and seller names, loan amount, and loan type. Nigerian due diligence teams evaluating US real estate acquisitions use sales history to understand a property's price appreciation trajectory, verify the asking price against recent comparable sales, and identify any red flags like rapid ownership changes or below-market sales.

Mortgage and lien data available through ATTOM shows existing mortgages, liens, and encumbrances on US properties — critical information for Nigerian investors and diaspora buyers to verify before purchasing, ensuring the property is free of undisclosed debt obligations that could complicate title transfer.

Hazard risk scores from ATTOM assess natural disaster risk — flood zone, wildfire risk, earthquake risk, tornado risk, hurricane risk — for any US property. Nigerian investors buying US real estate in climate-exposed markets like Florida, Texas, or California need to understand climate risk to assess insurance costs and long-term property value resilience.

ATTOM is exclusively a US property data provider with no coverage outside the United States. Nigerian developers building applications for the US real estate market or serving US-based Nigerian diaspora real estate investors are the relevant target users. Pricing is subscription-based with access tiers by data volume and endpoint coverage. ATTOM's climate risk scoring methodology — assigning quantified risk scores across flood, wildfire, hurricane, earthquake, and tornado exposure — represents a data product category that is increasingly relevant for Nigerian real estate as climate change intensifies flooding risk in the Niger Delta, coastal erosion in Lagos, and drought conditions in the north. Nigerian property developers and banks should monitor the development of Africa-specific climate risk scoring products that follow the ATTOM model but use African geospatial and insurance actuarial data to produce meaningful risk scores for Nigerian properties.
