So my wife and I have an unusual opportunity, and I want some guidance on what would be the next best step to take.

What is unusual with this one is that we'd like to set up an impound account to collect property taxes and home insurance payments from borrower monthly. 

So it's not unusual for them to take liberties they wouldn't otherwise, like taking favorite light fixtures with them or digging up plants.

I know it is unusual and I've been told 15+ times by local banks they don't allow it, but I also know there's people on BP that have done it. 

This request is very unusual apparently.My lender is now saying I should cancel my current policy and go with their recommended insurerBelow is the full requirements the lender has asked for General:1. 30 days notice of cancellation to the lender must apply and be evidenced2.

Or with the Secure Act, you can now do 100% bonus depreciation and take the entire depreciation deduction this year- best if you have unusually high income for 2020.Hope this helps!

It’s not unusual to get an applicant in this situation every couple houses but this was extraordinary.

It's very unusual in that neighborhood.

But, what you want to do is very unusual and seems like an internals control nightmare.  

I have a very small dog, and that's the least "unusual" and most traveled with type of pet, and even those accommodations are not always available.It is not your place to assume that she has friends/family that can take on any part of that burden.I would say you may have to find a way to accommodate her IN FULL - she needs a place to live while her unit is inaccessible, and she should not have to pay out of pocket for that issue.
