NFL's Greg Little -- Eviction War ... Over Hollywood Mansion

NFL wide receiver Greg Little has a big problem -- his landlords are trying to evict him from his sick Hollywood Hills bachelor pad ... but GL says HE'S the one getting screwed.

Here's what we know ... back in January, the 25-year-old free agent began renting the insane 3 bedroom crib for $15,000 per month. And things seemed to be fine until Greg missed a payment.

The landlord says Greg's rent check bounced -- and he's given the NFL player an ultimatum ... pay up or get out. Greg didn't take either option and is still occupying the home.

But Greg says that's a load of crap ... claiming he INTENTIONALLY withheld payment from the landlord because the house is essentially a lemon.

"When you pay for a high dollar house, you want everything to be smooth," Greg tells TMZ Sports ... "stuff was breaking left and right. They wouldn't fix the stuff."

The landlords have now filed court docs to force Greg out of the home.

Greg says he's not trying to be difficult -- he just wants to be treated fairly.
