French Montana -- Summer Party Pad Up For Grabs ... For $5.3 Million

French Montana paid $40k to rent out a secluded LA home for the month of July, but now the owner only wants to sell so it will set you back $5.3 mil.

The modern 6-bedroom mansion sits in the gated Los Feliz community of Laughlin Park -- where Scarlett Johansson and Natalie Portman have lived. The place looks like it's straight out of "Miami Vice" (the remake) ... with an ultramodern, all white, open air architecture.

There's a pool, a spa, and a home theater ... but the real selling point is the insane jetliner view of the city.

It's also photo shoot ready ... just ask Frenchie.
