Jennifer Lopez and Alex Rodriguez have apparently had enough of the first property they bought together ... because they're already trying to unload their NYC love nest, only 10 months after scooping it up!
We've confirmed the celeb couple is listing their kick-ass 4,000 sq. ft. Park Ave pad for a cool $17.5 million, as first reported by the NY Post. You'll recall ... J Lo and A-Rod bought the 3 bedroom, 4.5 bathroom apartment back in March, dropping $15.3 million on their first real estate purchase together.
As for why they're already unloading this primo location -- in the world's tallest residential building, btw -- think family planning. We're told the couple's on the hunt for something a little more modern family friendly ... remember they have 4 kids between them.
Check out the gallery ... the place has some insane views of the Big Apple.
