There is an online calculator that tells you how much interest you have to give them (no it doesn't matter if you actually made that amount of interest or not on the deposit).

@Scott Trench   ​    I saw that as well online - 90 day moratorium - basicaly no unsolicitied offers to homeowners impacted in specific zip codes.

Louis, Memphis, and Birmingham offer a good balance of affordability and rental demand, while online platforms, auctions, and networking with local agents can help you find undervalued properties.

is there a way for me to create an online STR guestbook for free? 

They’re doing this across all online platforms. 

To managed it a bit easier (when you grow to more than a dozen), it'll be better to have one online login and manage all 'child' accounts.

Subscribe to the local paper online, start to follow the real estate market locally.

You can also check their reviews online at Google, Facebook, or Yelp.

Look at other rentals in the area and see not only how they are advertising or promoting online but also the inside and outside of the rental so you can create a similar environment to try to replicate the same results.

You should be able to search (if your county has online records) for your tenant’s name and/or all previous addresses listed on the tenant’s credit report.
