Tiny homes and ADU's generally face a lot of challenges as they are a disruptor to the RV and mobile home markets.

Planning on renovating and renting at market rates.

This is not too horrible when the "days on market" are in the single digits. but it will put a small GC out of business if the flip does not go well.

The data might be a bit dated, but it can still give us a rough idea of what’s healthy in the rental market.

This could make your ADR less competitive, but if marketed correctly I'm betting that people might perceive more value, which keeps occupancy at least the same.I'm thinking of a model where you tell guests they have "add-ons included" like grocery delivery, prepared breakfast package, attraction tickets, inner tubes, etc.

Those figures are based on market data and info I received from a property manager who toured the property.

I have never done commercial investing and I am not sure how many off-market deals like this will come along. 

FIRST: This is ALL dependent upon your state and local statutes, so make sure you know what you are permitted and not permitted to do in your market with regards to terminating a lease.And your post is written by someone different about once a week here on BP.  

I moved from Columbus Ohio to build for clients and investors and sell it's the best market in the country. 

Is there a resource whereby I can run a search for, say, the last 6 months or 12 months for all properties that were purchased "off market", not listed by an agent.
