I have a few in Salt Lake city/Northern utah!

I'm an investor and agent in Salt Lake City Utah and have had the same exact thoughts as you have.

Many years ago, Home Depot and Lowes used to have professionals from each trade in those departments, most were retired etc, I find that less and less nowadays and find myself helping customers out when I hear an employee giving really bad advice, so just take advice in the big box stores with a grain of salt. 

I do have a handful of clients that have ended up using multiple CPAs just due to who their partners were on different deals, and even in those cases they almost always end up consolidating to a single CPA - taxes are enough of a headache without dealing with 3 different professionals who each only have a slice of the whole picture.If you are going to regularly be investing across the country, it doesn't hurt to work with a firm that has State and Local Tax (often referred to as "SALT") internal resources, though typically this does come from larger firms with larger fees. 

This is not going to work and you will be spraying money into a lake.

You might want to think about pulling up the carpet and taking a look. (2) Maybe the water delivery piping under the floor, hot or cold, has developed a pinhole leak and is spraying onto the subfloor from below. 

So, while it’s technically possible, I would take that concern with a grain of salt.

I live in Salt Lake though

There is a lot more to MTRs than my basic thoughts above, and I wrote this in a bit of a rush, so take everything with a grain of salt. 

You can probably "find a guy" for cheap but they will spray everything (blow and go) and cut corners.
