"Real Housewives of Beverly Hills" star Taylor Armstrong's days are numbered in her beloved L.A. mansion -- because TMZ has learned ... the owners are trying to give her the boot in order to sell the place.
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.
