Why who opens doors should be regulated is dubious, but it is in most states.

That's the only way this would work for you and the seller unless a cash buyer comes along which is unlikely at $93k/door.

I got a very good price on the building (about $25k per door), but it was a ton of work as in addition to tenant issues, there was TONS of physical distress (foundation repairs, sewer line and water line repairs, electrical upgrades, new roof, and apartment renovations needed for all units). 

Every door closed is an opportunity for a better door.

Our company manages about 500 doors throughout Southeastern WI.

Taking the doors off of the rooms when the appraiser comes so that they aren't rooms.

Easiest and least costly is to go there and spend a week or so to get everything in order.Another one is to hire someone trustworthy and pay them to put it in their garage or in a storage unit for a month

Kudos to him for doing it, but his rules and his dogmatic approach is also the same thing that made Open Door Capital a horrible venture because they skip over being pragmatic.

This has opened up a lot of doors for our investors for the highest and best use. 

If none of those scenarios apply and the building is in fact grossing ~$10,750/m reach out because the building is not in a $115K door neighborhood in which case I would be interested and can find a way to involve you and make sure you're compensated :)
