Texas Attorney General Ken Paxton and his now-estranged wife, State Senator Angela Paxton, declared multiple homes as their primary residences when applying for home loans, raising questions among experts about mortgage fraud, according to new reports.

The Paxtons have long resided in a suburban Dallas home, but also have mortgages on two properties in Austin, the Associated Press reports. Mortgage documents reveal they have declared all three of these houses as their primary residences, according to the outlet.

Declaring three homes as primary residences could have saved them money because interest rates on primary homes are lower than those on secondary homes, the Associated Press reports. The Paxtons could have saved hundreds of thousands of dollars, according to The New York Times, which also reported on the documents.
