If you're looking to treat this as a regular rental, then charging undermarket rent throws a monkey wrench in that. 

@Jim LynchSome typical minimum tenant screening requirements look like the following, but it depends on your market:-Renter has a gross monthly income of 3x more than the monthly rent-Minimum credit score of 650-Renter must have no prior evictions-No felons (or other notable criminal history)There are a number of different tenant screening softwares out there such as Zillow Rental Manager, TransUnion SmartMove, etc.Be sure to complete an employment verification by contacting the renter's employer and confirm the details they shared with you, landlord verification (if they have a previous landlord), credit check, and background check.

I’d recommend looking for a market that’s affordable and has good rental demand—local job growth or proximity to schools can be a sign of a solid investment.

Verifying last 2 years of rental history very important!

Any recommendations on how many rental properties per LLC?

I had one short term rental that was granted a permit earlier this year and I have been operating it for months now as an STR.

Questions:1) How many rentals do you have currently or have had in the past?

@Kyle Reedstrom assuming you are referring to Buildium syndication for rental ads?

Look them up online, call and interview several of them.
