ATTOM is a Convenient Source for Mortgage and Transaction Data

Public records are a treasure trove of insights into mortgage transactions and the real estate market, but combing through the different sources is time-consuming. ATTOM data collates property, buyer, and seller datapoints and uses smart analytics to deliver the information real estate professionals need.

Recorder Deeds

Complete public records with nationwide coverage of real estate transactions, such as sales deeds and mortgages, from over 500 million real estate and loan transactions in over 2,690 counties. This dataset can be collated into reports at various levels of geography.

Real Estate Transfers

This data originates from public recording of deeds at the County Register of Deeds or local county offices. Deeds may include the sale price, however, more often than not, a documentary transfer tax is used to calculate the sale price of the real property. When deeds are considered to be arm’s-length in nature, the calculated sale price is a strong indicator of market value.

Property Loan

ATTOM’s loan data includes details on loan amount, lenders, borrowers, , interest rate, and recording date, and other important loan features. The data are sourced from county records offices who record real property transfers, mortgages, deeds of trust, liens, and other real estate transactions.

Borrower / Buyer Details

Borrower details are sourced from public databases. The details include name, vesting, occupancy details, private or corporate ownership, as well as the census tract location of the property, loan-to-value ratio, and age of mortgage note.

Seller Details

Seller data includes the seller name, date of sale, and selling price.

Mortgage History

Mortgage history data is publicly available on individual properties. Details include mortgage performance from origination to termination, mortgage terms, type and purpose of the mortgage product, secondary mortgage market sales, second liens, and credit scores from one year before origination to one year after termination.

Loan Positions

Loan Positions

ATTOM’s logic determines the loan position when a borrower has multiple active loans on a property.

Real Estate Sales Trends

ATTOM aggregates sales trends by ZIP code and city level down to subdivisions and neighborhoods. The data is warehoused and updated monthly, quarterly, or annually and includes property addresses, lot information, buyer and seller data, and home ownership details.

iBuyer Trends

iBuyer data discloses the disruptive trends of the emerging iBuyer business models. Characteristics such as where iBuyers are purchasing, the types of homes they are purchasing, and the volume and price points provide data driven insights into the pace of the market.

Property Sales Price

Integral to real estate appraisals, property sales price data is used as a comparison when sellers are pricing their property. An accurate and realistic price is set based on this data and has a direct effect on critical metrics such as days on market.

Estimated Sales Price

Similar to property sales price data, estimated sales are derived using internal logic to estimate the sale price in counties where this data is not of public record.
