Attorney General Ken Paxton of Texas and his now-estranged wife, Angela, declared three separate Texas homes as their primary residence in mortgage documents, according to records obtained by The New York Times.

The possible misrepresentation could have allowed the couple to secure more favorable loan terms and save hundreds of thousands of dollars.

The issue, first reported by The Associated Press, emerged Thursday, two weeks after his wife, a state senator, filed for divorce, accusing him of adultery, and a little more than three months after Mr. Paxton announced that he would challenge Senator John Cornyn in what could be the Republican primary season’s toughest, most expensive race in 2026.

The Paxtons did not respond to questions about their real estate holdings.

The Paxtons reside in a home worth more than $1 million in McKinney, a suburb of Dallas, according to their voter registration records. That house is in the State Senate district that Ms. Paxton represents and the one Mr. Paxton represented as a state senator before he was elected attorney general in 2014.

The couple also holds mortgages on two houses in Austin, each of which they also called their primary address. Those houses appear to be rental properties, based on online listings. Mr. Paxton has disclosed rental income from two Austin sources on his financial disclosure documents.

Properties that generate rental income are considered investment properties and can be more difficult to finance than owner-occupied homes because they are considered riskier investments.
