(My inspector was garbage but that's a different issue)The appraiser if they had noticed a damaged floor when walking through, could potentially have made that an FHA issue, but since it was only revealed when you started to renovate I doubt they would have.

The roof in this property is my main concern with it being slate and I noticed it had a couple of loose tiles.

This is due to the “Notice of Sale” document which must be recorded and each lender notified in case of any foreclosure proceedings.  

He is month to month, and I let him know I am not going to have him here for September (i.e. 30 days notice, so August would be his last month).I would like to get him to leave sooner if legally possible, for my peace of mind and the safety and comfort of future tenants, if I rent other rooms in the house.  

If they are less-than-ideal in any way, then I'll be a little harder on them like only paying for portion or paying for the entire thing but then giving them notice of termination.

@Cody PetersenWe could likely make any of those evenings work with enough notice!

I would send a notice out and kindly reiterate the parking rules and the penalty if not abided by.

I also noticed with our housing market data that people from Boston are moving to Portland ME.

To my knowledge, this is the extent of what the city requires regarding notices. 

-Completely notice to quit/evict?
