The challenge will likely be obtaining bank financing without a track record in the LLC name.  

Get copies of the master insurance policy, CCR's, any recorded lawsuits, budget, bylaws, the count of owners vs non owners and I can give you some names

Look up the tax records for the property from the tax assessors website.

Depending on the website you can run a search for sales on four family properties as far back as their records go.You could also pay for a lists via website's like list source.

If possible I'm interested in purchasing a single family home & renting it out, while building a small studio/1br ADU for myself when I'm in town (live in NY but family is in MN).

I also don't want to spend a lot of money on sending and receiving payments.With an added bonus, are there any programs that can do all of the above AND report to the credit bureaus to help my tenants build their credit history and will record late payments if they miss them?

For those without MLS access, Zillow, Redfin, Trulia, and Realtor.com should get you the info you are seeking unless you live in a non-disclosure state, as home sale price is not public record in such states.

That’s why the SF isn’t in their records. 

I didn't have a track record and finding people willing to invest was difficult.

Also check eclipse for rental license records.
