Is this a dealbreaker?

[Bienes Raices]

I'm planning to go see this house in a few days with a realtor. In the description it says it has an illegal garage conversion but "seller may convert it back to garage". Would you want the seller to do something like that, or just get a credit so that you can get your own person to do it?

Also, the house will not qualify for FHA. That''s not an issue for me in my purchase, and I plan to buy and hold for years, but could I get burned on my exit strategy because of this?
