This is true even if the tenant pays rent for the last month.The tenant must pay the rent for all or any part of the time they stay during the notice period; though, they may choose to keep the last month’s rent in lieu of compensation."

I've tried a well recommend local bank and they are not able to help.1031 45 day period lapses tomorrow. 

There may be periods where the graph drops from 100% to 0% as it did in the last few days:If so, then everything is fine.

They told me I can do my due diligence during the option period/ feasibility study. which is pretty standard.

@Gage Green, is there a fixed period before the interest rate adjusts?

I have suggested licensing the STR properties with a nominal fee and a 2 year renewal period.

We also send out letters periodically when the owners aren't picking up their poop in the yard that they have 30 days to do the cleanup (or hire a pet clean up vendor that we recommend) or we will bill them for the cost and it is a violation when it comes time for lease renewal. 

If your bill came in high this month, it may pertain to the period before you shut the A/C off.

@Ronald Allen Barney thanks for the input, these are for investment properties and I always follow them on Zillow until they close (to see the close price), but I was curious if it was worth a checkin with the listing agent after the contingency periods expire to make sure they were on track for closing.

Doing it right is a repeated mailing campaign over a period of months and that frigging dinosaur that advocated "golden letters" in my market center, his name is mud to me now.
