Kathy, check out Anchor Loans as a comparable. 

The zoning office suggests reviewing the zoning ordinance, but the course didn’t cover zoning assumptions in detail.What’s the best way to verify zoning suitability and double-check zoning information?

I highly recommend checking out the book Turn-Key Revolution by Chris Clothier.

I'll check them out for sure. 

My wife and I do it separately and see what each of us may have overlooked. 

I'm not sure where your market is but I could help look at land costs. we are trying to educate building to rent or building investment properties as a new strategy to just buying the garbage new builds around the country. this fits on lots as small as 3500 square feet. you'd have to check local zoning but if I had what you had that's what I'd do or at least look into it. 

To check the proof in the pudding: look at Avantstay's host ratings on Airbnb or other platforms.

Quote from @Sherry McQuage: Make sure to check the zoning to make sure mobile homes are permitted there; check for any hazardous waste designation for the area; will you need to have the parcels surveyed out in order to sell the size you intend? 

Obviously this won't work for a  5 bed but if you are just getting 1-2 roomers  check the policy.

I would love to be able to fact check this.Park North (aka Life Spring Estates), Houston, TX - Sponsors: Inman Equity, Djuric Family Office.Best of luck, Cheryl
