If you're going down to the studs in the bathroom already, tearing out the window trim/stool/apron is probably the best bet.  

Part, yes, I am a sick twisted addict to this sport called Real Estate BUT also we had all the incentives for it via % based fee for service.   

And what is the mix of guests (couples, entire families with kids, grandparents, parent visiting college students, hikers/water sports, college football fans) maybe theme it to what people think of when they go there or provide things that would enhance their stay (paddle boards, video games, theater room, kayaks, really cool beds that have slides etc).

Sorry to not offer a connection, but for this one I think your best bet is to find the "land specialist" realtor in the area and get a CMA.If you want an extremely precise number hiring an appraiser is most likely the move. 

Others suggestions of a HELOC or DSCR loan may be a better bet for you with less tax return type of requirements.

I'd bet that you'll be able to refinance within those two years and your returns will look better.

And the neighborhood is even more critical as he said.I'd bet even a veteran Contr like Mr Paul would hesitate before giving a rehab $$ number based on a video alone.It will take you years of actual doing before you could even get a number from a walk-through.

Man made attractions like amusements parks, sport cities, etc., will have an ebb and flow of visitors depending on the current demand.

I really see Columbus Ohio as an extremely safe bet for the next 10-20 years.

Your best bet is to learn all you can and earn all you can over your first 2-3 years of college.
