Happy to provide additional information as needed.

I was wondering about if there was anything I need to do in addition to just filling out the lease and getting the SSID ect...

Have an additional $100K for more acquisitions.

In addition to education, focus on networking and thinking of what you can bring to the table (if even it's small... bring your ideas) when you reach out to experienced investors.

In addition, there is no longer enough livable area in the unit so one of the bedrooms has to be used as a living room and I have to put a door on a little passageway area and use that as the 2nd bedroom.

Many states, counties and municipalities have additional protected classes.Here is the blog post that this came from: https://www.biggerpockets.com/blogs/7520/47329-social-media-and-tenant-screeningI hope this helps!

Instead of 'returning' deposit from '15, and having two remaining write new check, can anyone suggest wording/letter that I could have the moving out tenant sign stating something along the lines of 'I, ____, have received my full deposit back, including interest, from my roommates Xname and Zname and do not expect any additional monetary return from my landlord, _____' ?
