I’m currently managing 45 doors and looking to add a property management software, thanks!

Oversized 3 car garage. 2182 square foot total.

If the drywall cracks in the next year or two, or the doors start to stick, then you likely have a larger settlement issue going on, and will likely need to call a foundation repair contractor. 

I helped a client purchase an SFH fixer with a detached garage.

I would look for a 2 bedroom 2 bath duplex with a one car garage for each side located between the two units and each front porch on the each end of the building.  

Two doors doesn't provide any sort of scale to make the cash flow more predictable. i would think hard if this is really worth your time, money, and effort...please explain the quote about two doors? 

I would like to use the garage as a game room for the kids.

Paul and I operate 10 doors in North Iowa.

For example he is trying to place a bookcase door to access a small amount of storage from the bathroom.  

There's also a detached two-car garage and workshop.It exists in kind of a twilight zone between commercial and residential.
