San Francisco 49ers star Nick Bosa is putting his luxurious condo on the market … and it’s a family affair — ’cause his mom is the listing agent!!

TMZ Sports has learned … the All-Pro defensive end is parting ways with the 3 bedroom, 2.5 bathroom pad in his hometown of Fort Lauderdale, FL — and he’s seeking a solid $1.75 million for the joint.

But it’s not just a roof and four walls the next owner is getting — the condo comes with a private beach, a top-notch kitchen with high-quality appliances, a wine fridge, a built-in espresso maker and marble and wood floors.

The whole building also features a clubhouse, heated pool and spa, pool tables, gym (duh, have you SEEN Bosa’s body??) and some billiards tables to boot.

If that’s not enough … the pad is just a short walk to a bunch of fine dining.

Like we said … Cheryl Bosa of Engel & Völkers Fort Lauderdale listed the place … so we take it it’s a special listing for Momma Bosa.

Nick — the younger bro of L.A. Chargers star Joey Bosa — is one of the top players in the league today … earning Defensive Player of the Year honors a few years back.
