You can also try contacting the bank directly for a more official "letter." 

I checked the permit history and it looks like it was officially a triplex since at least Feb 2005—so it’s past the 15-year mark.When I looked up the law, it looks like it mostly applies to evictions.

We have no established contract, or anything official, which should have been a red flag at first.Thanks again!

I own a duplex with my partner and want to make it official via an LLC.

I’m a huge fan of the podcast/YouTube channel and am already a couple of BP books in—it seemed like the time to join!

The managers take a higher percentage, but could be worth it to not have to deal with the day to day operation of running the STR and managing the turnover on the property.Be sure your HOA allows STRs if you have one, and you will need to obtain a permit from the county to be fully official for the STR. 

The town's zoning official can tell you what level of maintenance, upkeep, mowing is required.

Looking at your past posts, the fact that you’re on BP, AND that you have a YouTube channel (i subscribed), tells me you’re doing all the right things.

With all the other questionable actions going on right now you would think our gov officials would be very cautious when it comes to questionable "conflicts of interests."  

For recording/tracing purposes, it's cleaner if you have a separate bank account for your rental and channel all your income and expenses through it.
