This is a portfolio loan offered by local credit unions where you can buy up to 5 pure investment properties with as little as 5% down if you qualify, which you do have to qualify still with DTI, credit, reserve requirements, etc.  

Which entity do you require? 

If you were required to leave some sort of explanation for giving anyone a less than perfect rating, you'd probably either be justified (or felt justified), or if it wasn't something you wanted to spend time explaining you'd just give the 5. 

Make a note of any obvious maintenance or updates that are required.

Do lenders consider this a multi family and require commercial financing or is it considered a single family?

Quote from @Trino Martinez: I came across an article (link below) about a proposed bill (HB355) in Utah that did not make it out of committee that would include among other things a requirement for landlords to give 60-days notice for rent increases.

But as of now no requirements.

I think we had this option also but opted not to do it and as PM, if investor doesn't have a US bank account, we are required to withhold tax of 30% or so from every rent distribution.

Or if the lender requires that she be on the deed then you just meed to make sure that the client goes on deed as a tenant in common to as much as they sold. 

I also require tenants to carry renters insurance - this protects YOU from expenses they get hit with.
