The IRA can invest in real estate in addition to or instead of just stocks.Because the IRA is tax sheltered, there are strict prohibitions against any kind of self-dealing.  

So, typically, you will find that many of the applicants looking at a shared unit situation are doing so because there is some qualifying factor that is likely prohibitive of them being able to rent their own studio or 1/1(income, credit, etc).With that said, I am sure that you can find enough qualified tenants to fill your property.

Also, it usually makes a difference if you're renting out your entire property or just a portion of it (like a room or a guest suite), normally you can do this right away assuming that your local government allows this (municipality, county, HOA, etc..) and there are no deed restrictions prohibiting it. 

IMO, there is nothing that would prohibit a private buyer and seller from structuring a contract this way.

Sometimes even the city ordinances prohibit vacation rentals.The final thing I would mention is tenant screening.

@Eric Boakye,Coming at this from the insurance side, it would be my opinion as a fix and flip that insurance would not be cost prohibitive.

Some parks may tell you they prohibit 3rd part rental entirely.

I know my lease has language in it that prohibits this sort of thing, I would just inform your tenant that he signed the lease with the intention of being the only renter and that's what you're sticking with.

Yes, they can cap the number of rentals or prohibit them all together, assuming they follow(ed) the proper procedures.

Because a 506B prohibits advertising and a 506C does not many sponsors shy away from 506B as they gain experience and a track record.
