Secondary to good RE investment markets, my wife and I consider outdoor recreation nice for staying healthy and fit!

There's a lot of research you could do on VRBO/AirBNB/AirDNA to compare similar properties in terms of rates and occupancy, but my experience is that Gulf Shores and Orange Beach are more popular because of the nearby amenities, nightlight, recreation, and other things to do. 

Just wanted to double check before I recreated the wheel.

If you where going to be able to recreate the orginal layout, you would of been able to do so by the clues left behind by remaining framing, be it the "honey" holes where the toliets once where, the sizes of the holes in the joist would indicate what pipes ran where be it hot and cold supply, toliets, showers and other industry standard tell tale clues. 

My wife and I frequent AirBnB when we travel and have considered the potential passive income through this service.Near our home is a relatively popular recreational area.

Its the same thing in cheap markets were they sell say 130k new construction.. those deals usually have 10 to 15% gross margins so they are making 13 to maybe 20k if they are really lucky net profit but getting good leverage and pumping out 50 in a year.We will build about 40 homes this year.. so while we don't hit homeruns we make it up in volume and god willing the market holding and the star's aligning and every other lucky charm we can pull .Like @Will Barnard even though it was an outlier for us we did a 5 million dollar flip and made 1.5 on it.. but that was not something we could recreate .. and I don't have the stones to do that these days.. with my cheaper homes I know my bank will let me make them into rentals if they don't sell and with the rents the way they are they would cash flow or be a tiny bit negative as we rode out the market... 

I live in Minnesota where recreational use ins't permitted and I'm not sure if they have a prescription for medical use or not.

Especially since you are in a recreational state

Quote from @Daniel Netzer: Hey guys, I'm based in a very recreation-heavy area in Central Oregon. 

People also think of Nebraska as flat plains, but over there by the Iowa border there is a fair amount of topography and outdoor recreation to do.
