I'm looking for suggestions on how to spin this for the apartment manager's so that I don't have to pay the full early termination fee. 

Within a very short time you will have learned so much it will make your head spin, as long as you work with professionals as they will already be at some level of scale and volume, and gained valuable network connections.

Just spinning wheels like a hamster. 

My point is that what I see from hipcamp here is just a me too trying to spin something that has been around for decades and it's already very well represented both by companies and by parks and by guide books and by listing sites. in other words, nobody struggles to find a place to put their RV.

My spin is: Unless your bush "over-growth" is causing complaints from adjoining land-owners, or creating "code-enforcement" issues, ...keep it "as-is"! 

There are so many different niches in REI it is very easy to get distracted,  interested in everything, overwhelmed and then you will just be spinning your wheels and traveling nowhere.

So when this women passes away and the heirs find out you got there relatives house, at 40% market value, how do you plan on spinning things then? 

If the home has equity, you may be spinning your wheels trying to short it.

My mortgage is $2,700 but I have so much into this house, ROI is a long way off.In any case, then I found Loftium.Loftium’s business is a slight spin on the “traditional AirBNB arbitrage” you have read about.

One thing I would add is that looking for 'off-market' properties can sound like the sexy thing to do in real estate, but the reality is unless you are 1) buying in cash or some near cash loan equivalent and 2) planning to look for off-market properties on a large scale, I think you will be spinning your wheels.
