What is your overall exit plan - buy and rent? Buy and wholesale?
Buy and retail? Nothing closer to your home? 50 miles can get to be a major expense with the current gas prices moving upwards! What experience do you have? These are the kinds of things needed to evaluate your particular situation.
how much can you sell/rent it for (quickly) and how much time and $ will it take to fix it? Can't be a high end park... Do you have experience with park tenants? If it needs repair, do you have experience w/ MH repair?
Rociel, its a bit like pulling teeth to get info from you on this. You need to determine all of your expenses in acquiring the home which includes purchase price, repairs, taxes owed, state transfer costs and lot rent until sold (I budget two months on all of mine).
Then determine what you can sell it for on a note.
If my calculations demonstrate I can sell it for twice what it costs to acquire, I move forward. Your requirements might be different.
There are many other finer details to learn in between but that is a rough sketch.
