The only thing that I would be cautious of at the moment is the current slowdown in airBNBs in many market due to over saturation and possible legislation that can limit STRs in the future in your market.

Collecting you payments on a financed option won't hit the threshold for all servicing requirements as much of that is intended to conform banking and mortgage servicing issues, but you are still subject to the collection practices for consumer debt.Foreclosure laws have been touched by federal legislation as well, time limits for notices and demands, restrictions on who can "assist" someone who is in foreclosure, credit counseling or those suggesting how to avoid or seek relief from foreclosures are required to have a license under HUD direction unless they are an attorney.

This is much cleaner and it doesn’t violate any Dodd Frank legislation. 

There is some other legislation to support this as well but I think these types of properties in Utah will be valued more similarly to its multi-family counter-parts in the new future.If the lifestyle factor is too hard for you to get over in some instances you can look at new builds that are being built with ADU's as well.

First, check out this article: https://www.al.com/news/index.ssf/2018/10/airbnbs_largest_alabama_market.htmlIt highlights state trends with Airbnb and that the trend is a positive outlook for legislation to go in your favor for hosting. 

Have you had experience with "legislating" chores like that in a lease?

Generally PM's are required to take continuing education, which is often focused on new legislation as well as basic "refresher" classes on basics such as Fair Housing and LL/Tenant laws, Fair Credit, and even Safety.

Running as a business is what has gotten so many communities legislating against them.

From the research I've done (I wanted to do everything by the book), we found that there is no legislation to regulate Airbnb listings in Providence and the only proposed legislation was proposed last June (2018), which would make require you to have a certain amount of property insurance coverage ($300k) on your rental, register with the city, meet non-discriminatory and safety standards, make sure you collect and pay the hotel/transient tax, and bar anyone who uses affordable housing funds (FHA, VA loans) from short-term renting their home while they are not present.

Keep an eye on the Legislation.
