The Anacortes ban happened fairly quickly, so I agree with you, it is hard to base an investment solely on something that jurisdiction can ban.

It's an educated experienced based choice to buy or sell RE.

It can be a tricky market to navigate, with different cities having different point-of-sale requirements, and Cleveland has lead-based paint requirements for rental properties.

However, he offered no assistance on the re-platting process. 

Based on some rough calculations, once fully stabilized and running (including property management), I predict the tiny home community to cash flow around $20,000/month and be worth roughly $3.5 million!

I am seeking recommendations for companies or resellers that specialize in App/Card-based Washer/Dryers.

New construction may be an option, many builders are offering rate buy downs and closing cost assistance and then you get quicker appreciation when they continue to build out the community.

I recommend looking into areas near economic bases - close to Nationwide Children’s Hospital, Ohio State Campus, New Albany, etc.

Personally, I would go after base hits 

I get texts/postcards/calls offering me cash for the house a lot, but I don’t want to sell the whole thing outright, I want to retain my ownership and investment and build a property empire with someone who wants to invest - and I’m totally okay with full involvement or silent partnership.
