One particular property that I looked at was converted from single family with a one bedrom unit on the first floor and two single room apartments on the second floor. 

When you go from a single family to a Duplex, it becomes "comercial" property and according to (Michigan) the local building dept, I had to hire contractors. 

Buy some single family, buy some duplexes, buy some 4plex. 

Are you going to live there also, or do you want to operate a shared housing model in a single-family home with tenants?

LTR Single Family Rental What made you interested in investing in this type of deal?

@Ana Vhan there are many commercial options where you can add multiple locations/multiple states onto a single policy.  

Buying a single-family home with a detached garage and converting it to an ADU is much simpler.

its highly risky for most mom and pops to sell on sub to.. and its simply not a way for those without substantial wherewithal to buy property and keep the seller safe..

I was told Tom’s mom was going into cardiac arrest.

The most successful people that I have heard on podcasts and met in real estate know that it is all about getting a single here and there and then going to get a homerun while doing those singles.
