Nicely done.I have found tired landlords who have paid off their properties; I found them by riding my bike in my neighborhood and striking up a conversation. 

Look around, strike up a conversation with the locals, and perhaps grab a drink with real estate experts.

I only offered it knowing that rents could be increased to around $250.I am trying to strike a deal with doing Owner Finance since a lot of banks I called don't work with Mobile Home Parks. 

I can always change my mind depending on their response to the lease violations.Oregon is a very tenant friendly state and we have a 3 strike rule.

The problem I've ran into is that a buyer that has been doing auto-deposits monthly has had 3 strikes when it comes to "in-sufficient funds," and at that point MSE requires they be placed on mailing in checks only.

Best of luck in striking a deal that works for you and the seller. 

or in order to do events there is a minimal lot size which should strike for? 

That strikes me as approximately the average, although I have seen some go as low as $4 or so.

Start the negotiation at current rents, and have a strike price that you won't go beyond, knowing what you can operate it at.

They seem to strike a balance between promoting businesses and jobs.
