Johnny Manziel: Goodbye Cleveland ... 'Sold' Sign on Suburban Crib

Johnny Manziel just cut his last tie to the city of Cleveland ... cause there's a "SOLD" sign on the front of his nice suburban home, TMZ Sports has learned.

Manziel bought the 3 bedroom, 4 bathroom home -- in a private golf course community -- back in May 2015 ... one year after the Browns selected the QB in the 1st round of the NFL Draft.

He paid $438k for the place ... but after the Browns cut his ass, he put it on the market for $489k hoping to turn a $50k profit.

Good news for Johnny ... he got a bite. We're told the deal isn't "officially" done but it's expected to close soon. In fact, the realtor's so confident, there's already a "sold" sign on the front lawn.

No word on who bought the place or how much they paid -- but here's some advice ... get the place deep-cleaned before you move in.
