Like washing down the stoop with strong bleach, or cleaner? 

I added value and increased rent by adding things such as appliances, laundry, flooring and central AC.

When i called him and asked what his plan was he acted like he didnt know he was supposed to be out and said he wants to stay and "would pay".

Or any recommendations on how you keep track of WHATS COMING UP for example septic wash out, how do you keep track of when things like that are due? 

And the tenant may be right, all they said was he was a professional, didn't say what he was a professional at : ) Given the dude was a pro, did he pull permits to run electric from the house, underground to the garage? 

We started to add coin-ops conversion kits for the laundry machines in our buildings to help cover the costs of operating each machine and now tenants are complaining. 

The original thing was he was supposed to start in October of 2020 and that building was supposed to take him roughly two weeks to get done beginning to finish and the reason why is it was an 800 square foot guest house it was already framed up the only thing he had to do was get the electrical done put the drywall in floors trim roll it on out and be done within two weeks if he was taking a long time it might take him a month.

@Stephen Dallas if that’s cement in the front, do a good pressure washing.

Washing machine hook up but not to a drain, A/C condensate not routed to outside but in the walls (that was fun), electrical issues that were to be "repaired" but were not actually.
