I was also going to suggest the the hillside mentioned may be unstable, in which case $100k + to dig down to stable earth and pour cassions isn’t out of the question (with engineering, geotechnical, etc)

First, congrats on digging in and driving for dollars.

I will do some more digging see if I find a lender willing to do this.  

Through some digging around, Airdna says our Airbnb market averages 47% occupancy rate with $1,250 revenue.I find this hard to believe given the area is 20 minutes or less from the airport, large homes, great neighborhoods, great food nearby. 

Don't spend a ton of money on this, audible a few books and dig into groups.

I would dig deep into your city water and sewer hookup and get a quote on install on that. 

As you guessed from the title, I'm looking for insight on how to dig into a potential ground up development opportunity I was presented with yesterday.

Make sure that when this happens, there is enough land available to install a new leach field, lest you may end up paying for digging out an existing leach field as well.Get a copy of the septic system design from the town's building department. 

They started digging deeply into at our financials and the underwriter came back saying that they weren't going to do the loan.  

Let me know if you would be and I can try and dig up the details and send them over to you.
