I started managing rentals in 2010 and it remained a strong market in my area.

With 5 days already that's a super flexible cancelation policy (even if Airbnb calls it "moderate") and I doubt you'd re-book that close.But yea, my confusion still remains what the heck these guests are doing that they're regularly unable to travel for an entire 3-day span. 

My furthermore questions are: Looking for a technique to avoid disrupting my current mortgage if title/deed name change is required to engage lender and that lender calls to accelrate mortgage, and i need to pay-off remaining balance in 1-month.?   

Location, sales price, market rents of residential, what % of the residential are you going to reside in and what rental income remains, is the office currently rented, condition, your FICO, your income  then I can tell you what is available.

The qualifications and rules for 2022 remain the same, however they will be adjusted starting in 2023.Here is a case study where an apartment complex owner in North Carolina utilized the 45L tax credit.

I'm questioning the alerts stopping when the rent remains paid.

As the articles note though, those are just proposals at this point and it remains to be seen what the City Council will do.My guess, based on nothing other than my own guesswork, is that they’ll continue to allow AirBNB but restrict it in some way such as a cap on numbers of listings, restricting it to only owner-occupied properties, requiring fire inspections, etc.

These expenses will wipe out your remaining $13k. 

Unless you are adding structures and appurtenances, you do not have to use a GC to remain lawful. 

Depending upon your occupancy type for the property and what the ARV vs the remaining balance on the note are, you may not have to come out of pocket with too much money, if any, on the refinance.
