Kim & Kourtney Kardashian Closing In On $6 Million Miami Pad

You're looking at the $6 million Miami mansion that Kim and Kourtney Kardashian will most likely call home for the next three months while filming their next spin-off show, TMZ has learned.

Sources close to the production tell TMZ ... crew members have been tasked with finding a home for the K-squad while they shoot their upcoming reality show "Kim and Kourtney Take Miami."

If you didn't watch the first "Kardashian" spin-off in Miami ... Khloe and Kourt  stayed in hotels during their stay ... because they're swanky and awesome.

But this time around, Kourt -- a mother of 2 -- decided she wants to be in a house ... a really big house.

We're told ... the front-runner is the $5.8-million-dollar Mediterranean style MANSION pictured above ... which boasts 6 bedrooms, 6 1/2 baths ... over 5,000 square feet ... a pool ... AND an attached dock with room for a 100' boat.

Which they totally need.

Sources say they are considering other places, but at this point, it would be a shock if they didn't wind up in this place.
