Mortgage Interest Rate Field Population – CUSTOMER

Short Answer (Customer-Ready)

Mortgage interest rate fields are only populated when the interest rate is explicitly disclosed on the recorded mortgage document. Many counties do not record interest rates, particularly for standard fixed-rate mortgages, so coverage is naturally limited. An empty value does not indicate missing data or an error—it reflects the absence of rate disclosure in the public record source.

Detailed Explanation

Interest rate values are sourced directly from recorded mortgage documents when the rate is explicitly disclosed.

Interest rates may be blank when:

• The county does not require rate disclosure
• The mortgage document does not include the interest rate
• The loan terms are considered private and not published in public records
• The recorded document lacks standardized rate information

ATTOM does not estimate or infer interest rates in the base dataset. Only explicitly disclosed rates are populated.

Expected Coverage / Population

At a national level, interest rate population typically averages 10% to 15%.

Coverage may vary depending on:

• County recording practices
• Loan type
• Time period

Lower population is expected behavior and reflects public record disclosure standards.

What This Does Not Mean

An empty interest rate field does not mean:

• The transaction is invalid
• The record is corrupt
• Data is missing from ATTOM systems
• There was a processing error

It simply indicates that the public record source did not include the interest rate.
