I am a FORMER engineer, recently retired.  

You should try to talk to all tenants.A 10 unit retail property will likely require a full PCA from an engineering company, a ALTA survey and a Phase 1 environmental.  

I was determined and wanted something that I could sustain for the long term for my family's livelihood and control the effort I put in and the results I got from that effort.I specialize in sourcing properties for fix and flip investors nationwide (wholesaling, but with real-world experience and closed profitable deals for myself and my investor partners) with a roadmap to acquire rental properties as finances permit.A lot of our deals are currently coming through organic search as I have a background in substantial traffic generation through search engine optimization and organic means.

(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.

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?

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

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

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

I've had some blue collar ones all the way up to software engineers and everything in between. 

Yesterday I was talking to and architect and engineer who is owed money.
