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.

Cedar offers natural resistance to rot and pests with a great look that can enhance property value, but at a significantly higher cost and it requires regular maintenance to retain its appearance.

For credit score requirements, Washington state law discourages setting minimum scores unless a "business necessity" is demonstrated.

You'd need to ensure your ARV is 20-25% higher to get your original cash back out while meeting the refi equity requirement. 

Lots of little houses on large lots, some with multiple units (can be cash cows) built before permits were required so grandfathered-in.

And if so, what is the cost and prospect for collecting something, certainly not all, but something.My thinking is that if it shows up on their credit, it may hamper employment, car purchases, rental applications, education funding, etc and at some point they would need to pay me to go forward with some major life steps over the next 10 years.Your time and money would be better spent updating your rent requirements to get better tenants, increasing deposits if allowed and proactively evicting tenants who are behind so you don't get back in a position where someone owes you a substantial amount of back rent.
