Rachel Uchitel -- Turns BIG Profit In NY Real Estate Deal

Rachel Uchitel is making up some MAJOR ground on the millions she gave back to Tiger Woods -- TMZ has learned she just raked in a $330,000 profit after flipping her NYC apartment.

Uchitel bought the swanky 3-bedroom Park Avenue pad last year for $1.62 mil -- renovated the place -- and put it up for sale because she had a gut feeling the time was right.

Turns out Rachel has one helluva gut -- because she just closed a deal to sell the place for $1.95 mil ... not bad considering the real estate market isn't exactly booming at the moment.

We're told Rachel is pretty fired up about the deal -- and plans to reinvest in more real estate in the hopes of hitting the jackpot all over again.
