@Todd FithianI'm not a lender and certainly not an expert on the subject so take my input with a grain of salt. 

I'm not a lawyer so definitely take anything I say with a grain of salt but you are more likely to get into a car accident and hurt someone pretty badly than have a tenant sue you...someone you hurt in a car accident can come after you and everything you own, so having all your properties in several LLCs will not save you in that scenario but having great insurance just might...Of course to get the most protection possible is usually having a good combo of corporate structure and decent insurance but when costs start to add up and you only have one property to start with you have to see what gives you the most protection and bang for your buck.Good Luck :)

AirDNA is a very powerful tool that can help determine this, however unless there are a sufficient amount of 3 unit STR's in and around that area, I would take the numbers with an extra grain of salt.

We currently live in the Salt Lake City area and the market here has gone wild over the last few years making affordability on duplex and triplex units not impossible, but fairly tough.

Some good, some bad take them with a gain of salt.  

I'm more of a MHP newb, so take this with a grain of salt and maybe someone more experienced can check me on this, but I think it's overpriced. 

I am just getting under construction on a new build 4 plex in salt lake.

I recently got some quotes to build a 2 to 3 car garage with a 1 br 1 ba ADU above, and the quotes I was getting were in the 175-225k range to design, permit and build it (and I'm in Salt Lake, which I would have thought would be a cheaper place to build than LA). 

Salt Lake or Utah Valley for the Mtn biking and skiing and meeting people in your age group that are doing things outdoors.
