Jeremy Renner -- I Unloaded My 'Hamptons House' For a Fortune!

Jeremy Renner just got rid of the last vestige of his failed marriage ... the house they lived in.

Jeremy sold the house for $4.3 million, a solid win given that he bought it in 2009 for $1.35 mil. But we're told he spent a lot of money on renovating it.

It's pretty cool ... 7,000 square feet, 5 bedroom, 5.5 baths ... it's listed as "the Hamptons in Hollywood."
