The US single family home equity TAM for originations in 2025, including 2nd closed-end mortgages and home equity lines of credit (HELOCs) is estimated at 2.15 million loans.
The single family home equity TAM
We define the home equity total addressable market (TAM) as the total number of originators and originated loans in the US, backed by single family residential properties. The TAM is created by aligning and reconciling lenders and loans across different data sources and reporting frequency by period.
Forecasting and tracking the TAM
Forecasting the TAM is challenging since numerous factors drive the actual prime mortgage rate available to borrowers in any given month. In order to provide a practical baseline for management reporting, we track & update loan volumes quarterly, and in some instances monthly.
