Taylor's been renting the 4,800 sq. ft. Holmby Hills home since 2008 -- and it's been featured prominently on "Real Housewives" ever since -- but sources close to the reality star tell TMZ, she recently received a call from her landlord informing her the owners wish to make a sale.
The house was listed last week for $3.7 million.
Sources close to the owners -- who purchased the home in 2006 for $1.65 million -- tell us Taylor's been a great tenant ... it's just time to make a change.
Taylor tells us, "It's been a fabulous home for my family, and I'm looking forward to something new and stunning for [my daughter] and me."
It's unclear where Taylor plans to move, but until the owners actually sell the place ... we're told she ain't budging.
