John Legend My Real Estate Skills ... Are as Hot as My Fiancee

John Legend can add real estate GOD to his long list of accomplishments -- the singer just unloaded his NYC condo for a whopping $775,000 PROFIT. Yeah, we said PROFIT.

Legend bought the 1,359-square-foot East Village pad for $1.9 million back in 2009.

Unfazed by the real estate market, Legend listed the crib a few months ago for $2.9 million -- and made out like a bandit ... selling for $2.675 million, according to docs.

The place is sweet too -- designed by primo designer Andres Escobar -- it's rockin' floor-to-ceiling glass walls, awesome NYC views, rooftop deck and swimming pool ... where his fiancée Chrissy Teigen probably swam half-naked.

That sale price makes sense now.
