"The salary of a U.S. Senator is $174,000 per year. This is Joe Biden's house.... seems legit," Eric Trump wrote in an October 17, 2020 Facebook post.
He repeated the claim in an Instagram post liked more than 100,000 times.
President Trump and his supporters have repeatedly made unproven corruption allegations against Biden, often focused on his son Hunter, during the 2020 campaign.
A Google reverse image search of the house pictured leads to a February 2020 Wall Street Journal article. It featured that photograph and those of other homes in an examination of Biden's "passion for real estate" which, the article said, often stretched his personal finances.
The home pictured is at 6 Montchan Drive on the edge of Wilmington, Delaware. Records in New Castle County show Biden held mortgages on the Montchan property which he acquired a deed to in 1975 and sold in 1996.
Eric Trump correctly states that a US senator's annual salary is $174,000. But when Biden bought the property during his first senate term, members of the chamber earned $42,500 a year.

The mansion was "all overgrown, boarded up" when Biden found it, author Richard Ben Cramer wrote in his 1992 study of Biden and five other presidential candidates, "What it Takes: The Way to the White House."
"Joe did a $200,000 deal for the house. That was more than he had, of course," Cramer wrote. The Wall Street Journal gave the price as $185,000.
In 1996, Biden sold it for $1.2 million, according to the Journal.
Property marketplace Zillow has said Biden and his wife Jill bought their current Wilmington property in 1996 for $350,000 and built a house there. New Castle County records show Biden satisfied a mortgage on that waterfront home in 2018.
