Lenders often require a home to be in good condition, and an older or partially replaced roof might not pass inspection.

Keeping in mind that I am not a lawyer in any state, and, therefore, can only interpret laws for entertainment purposes...

Multi-family without separate meters may need more unique billing arrangements such as passing the costs through to each tenant on a square footage basis.As far as insurance, landlord will have to maintain their own insurance per mortgage requirements.

If there’s any other advice you can pass along that you think of, I’d greatly appreciate it.

I heard about flex spacing in a passing conversation at a recent event. 

I went to the courthouse in Birmingham Alabama to leave it legal documents so as I was there the lady had let me know that as of 2021 they passed a new law that when you buy a tax lien a house you are not allowed to rent it out renovate it or even step foot on the land or in the house

They dont always tell you this, but you'll find out once you start conversations.I went through this about 3 months ago, and so many banks passed me up.  

When I listed it I adjusted the rent to be a little higher than the comparables in my area, because it was one of the nicer ones in the area but I can't seem to get a renter. over the last 26 days, I have had 46 inquiries and 14 applications, of those 14 applications about 5 of them passed the background check and credit history check. some of them I could not get ahold of their employer or landlord which was a red flag for me. 

If the neighborhood looks run down and you wouldn't live there, I would pass on it.

A renovated older house can pass inspection but once someone is living in it and putting daily stress on the house, there will be repair issues.
