I bet the rate of Engineers going homeless is all but 0. 

It'll be the most accurate talking to boots on the ground and not an algorithm. 

Nobody should be surprised, we literally social-engineered this. 

I’ve tried to do a retreat of A-frames in the mountains but ran into land/engineering issues, multiple times. 

You have a personal issue- car engine blows up, so you tell your tenant that they need to pay double the rent for one month so that you can get your car fixed?

(as permitted by my engineer) My permits are good for 18months.I am working with a builder that thinks we can do the 20x24 cabins for 100k each. so that's 600k plus another 200k for site work.i think the cabins will fetch 225 a night. however lets use 125 @ 50% occupancy. that's 22k x 6.

I am a FORMER engineer, recently retired.  

I would have an engineer analyze first and do the work they recommend.

I also have masters degrees in both engineering and finance.

Then a Civil Engineer, an Appraiser to determine what having a four unit would be worth, then a loan using the evaluation.
