If you submitted an itemized breakdown within 30 days of your move-out date, there should be no issues.Did you take any photos for your records?

You're looking at real estate as if it trades on a screen.

That would be more than enough for me with a tenant I have a track record with. 6.

I did that (posted the notice on the screen door and took pictures), however don't know if it's legally served. 

In my market there are 2 reasons that keeping is smart.  1) the historical long term appreciation is on going, going back to when records started tracking the appreciation 2) the property tax is near fixed cost.  

Supply will be a Tale of Two Halves: In the multifamily sector, we will see another year of near-record setting supply hit the US.

Here's a detailed guide on how to screen applicants: Application Screening Guide 

If that happens then the tax record is updated by the effect of transferring the property.

Also if your sale price for the business was driven by some value add, better record keeping, or was underpriced to begin with?

Thank you I had a good experience with them. 5-6 days closing is a new record !
