If it blends into the crowd you don't stand a chance in my opinion. 

The home itself was in a great location and the neighborhood had a nice blend of homes with much higher values.

Would this blend lines for the sellers between debt and equity?

They are all like a blend of the Playboy Mansion and a French art museum.

Sellers hope for all cash buyers, or they can assume in place debt and still pay a premium, or are 1031 exchange and put 60% down for almost zero cash flow and hope blend up with rental increases and hope for refi in 2 to 4 years if Fed starts reduces rates again.  

You should also look into HELOCs potentially, rate will be high, but blended with your current debt will still be reasonable

BUT, this property is approved for 20 total cabins that we'll long-term build out (plus RV sites), and I think I want to integrate a hybrid system of scheduling -- some on Airbnb, but also my own website (utilizing Google adwords, current web traffic, etc) and blend the two platforms. 

It is not recommended to try to refinish only damaged areas of the floor, as it is nearly impossible to unnoticeably blend those areas with the rest of the floor. 

I'd do the math either way and check if your blended rate by throwing your (FHA P&I payment + PMI Monthly payment) into a mortgage calc, filling in the purchase price and working backwards to get a rate %. 

These have to be blended, but I don't think the government forcing such laws on LL's is the correct way of going about this.
