I would start by contacting the housing authority in the county were your rentals are - or do a google search. 

FHA is also not a great option if you have any cost to cure issues unless lender and title company have a history of working together. 

@Danny Smith depends on your work history.

Because a single room will be much cheaper than a typical apartment or home, you are likely going to have a larger portion of tenants being people who may have significant financial constraints, poor credit, eviction histories, and in general come with a little more "baggage". 

Each Housing Authority uses their own process for setting rents. 

2) I’d prefer to ge the loan in my name to build my equity and credit history unless you suggest otherwise?

If you recall the history of the 2017 Trump tax reform, campaign promises and early proposals had very little to do with the eventual tax law changes.

It's not that I don't still make as much money as I did with my W-2 job(actually will make more) however I am now no longer able to get "conventional loans" due to they all seem to want 2 years of work history.

Before buying just get the payment history and current lease and a walk thru to make sure they are the kind of tenants you want to lease to.

One issue I've read is since they are pretty new ("just a few decades"), there is limited case history on them.
