I recently bought a property (using BRRRR strategy) but we had an offer in on one that just didn't work out after inspection.

If it looks like she will work out I'll let you know.

You will have to seek (and most likely pay) a licensed professional to work out the details.  

I routinely fill holes and touch up as normal wear and tear.

Im just not sure how it would work out if i had a high debt to income ratio even if i had all three units rented out. 

He added plenty more amenities which can be seen on the listing at UK property listing He has listed it for sale at 895 GBP which would work out to a rounded 1.15 million US Dollars.

If the schools, streets, shopping and entertainment areas look like a C, attracting residents to pay the higher rates by upgrading the property to a A/B as you suggest (higher than the surrounding area) is typically not going to work out so well.  

Discuss possible solutions, either she stops, get more insurance, give u profits or whatever you guys work out but it should be a solution out there that works for you.Don't waste time gathering more facts if you clearly see your place on Airbnb.

Luckily we found this one off-market deal that we were able to work out.

You can contact him directly and try to work out some sort of deal to get the lien released prior to close, but if he knows you're going to close he has little incentive to cooperate and it sounds like he knows the game better than you do.
