Those cost in terms of lost rent, but also cleaning out the stuff that was left behind.If your place is managed by a PM, expect a 1 month vacancy (only once I have had no vacancy with my PM manage places, and once I had 2 months as they messed up and held it for a person-friend of the owner-who didn't put down a deposit and then they dropped the ball). 

Basically hold the world by speak my language and use my money, and we'll be golden.

I am an Associate Broker in Maine, been helping others get their STR properties, but now getting the ball rolling for my own properties!

Wow that is some golden advice thanks! 

A 2 stage is like a pitcher with a fast ball and change up.

. - If I were to find some creative renter solution and low-ball the market rent at $1700, I could only put in about $180K total assuming a conventional mortgage to generate acceptable cash flow.So, apart from increasing rent and managing the property myself what are ways that I could make something like this work?

Just do what @John Underwood said and you should be golden.

And your idea of storage units on the park is golden I think. 

when lehigh was put in they punched in roads to 250,000 lots.. one can google earth it today and see blocks of lots with like 2 or 5 homes per 50 lots.. lots trade there when its good times for 20 to 25k and bad times 2 to 10k  like a ping pong ball.. the GFC took down many land plays even out west..

There is no crystal ball of when we can sell we have been trying to.
