The door knocking for us is used on the realtor side and is more to get the know the neighborhoods but others I know that have used it for getting flips or wholesale deals say it works great.As for which one is best I'd jump back to needing to know your financials/time restraints. 

My brother looked at about 50 houses and they all had some form of lack of permitting, back taxes, no legal road access, etc.2.  

Since you are now up against it, I would first see if they are planning on moving, explain the situation, but back that up with an attorney ready to go.

interest rates have more than doubled since the end of 2021.  

I did a lot of research back in 2019 when I was deciding what market to invest in.

Where I am in Texas if it is a normal loan from normal bank, they step in the day before the sale or morning of the sale and get it resolved and the property never ends up in the sale.If the loan has small balance, or is some kind of private money loan or I would say unsophisticated lender then some chance it goes to sale.

I was given the impression that it was a special deal for us, but as I read the engagement letter, the money back guarantee was a standard language, offering clients 30-day money back guarantee. 

Clearly the big push-back from Curbio would be their need to maintain similar decision-making control on the improvements.

More maintenance on the balcony depends on the values. we have 7 zips we build a triplex in and some of them we have considered adding balconies if the market calls for it. another way to do it is on the back where the walk up is if they are truly apartments you can add it there. depends on the level you are after. 

In kind of a reverse sub 2 when i sold my logged over timber land we took back the note the hypothicated it So our bank was aware and blessed the transaction..
