Having worked from home for a long time I know the climate has changed and working from home is more common/acceptable.

Some of the more common contingencies include: financing, appraisal, title, and inspection.

It doesn't bind you with common liability risk the way a partnership does.The legal website NOLO.com explains it this way:https://www.nolo.com/legal-enc...Joint Venture.

This is very straight forward and common situation.

The place has improved a little, because Dough, Thomas, and myself have controlling interest in that those communities... don't expect anything amazing, turnover is very high, and bank foreclosures are common at those price point, so much so, we don't even buy them for that price.

@Austin Shute if you intend it to be storage for the whole building, you'll need to figure out how to connect it to the common areas / hallway so all tenants can access it.But usually what folks do in this situation is combine the top floor with the closest unit and make it a bigger unit (a "townhouse" unit), rather than using a top floor for storage for the whole building.You might have to remove a door or two to connect the two units so the building inspector doesn't think you're going to keep renting the top floor as an illegal 5th unit, but as long as that's done I think you might be able to keep the bathroom up there.

I live in Houston where this setup seems relatively common but am not sure if that comes with tenant issues around a shared yard, etc.Thanks!!

Very common for the lockout policy to be outlined in the lease.

Commonly, not always.
