But ads a few $1k for water proofing paint, to much much more

A few questions here:Do you setup completely different bank accounts for collecting rents and making payments?

The president also claimed that maybe (yes, he said maybe without any concrete proof because he said he said how my tenant drives and she always had to go back and forth a few times to get into garage) it was my tenant who hit the garage door and damaged it.

On the day of closing the title company will handle all of the paperwork and you will collect a check for the difference in prices between the two contracts.

So the process server may be confused thinking  you are collecting rent when in fact you are not. 

@Brandon Sturgill I don't have the knowledge/time to use only data I collect myself yet.

I delivered 30 day notice to quit mid March since it was not in writing.2nd floor had not paid rent since December 2020.I contact both tenants once I was on record as owner to let them know I would be coming by to collect rent.1st floor paid (there had been no previous issues with rent being paid)2nd floor ignored my request.

Window wells can collect water, even if they have covers on them.

Do proof of funds come first?

@Jason Merchey In my experience, we've always accepted a signed lease regardless of age (+ proof of deposit if its brand new).
