Figure out how much they would have to raise the monthly fee to go from negative cash flow to positive cash flow and then to be safe I would double that amount and assume the Hoa fee will go up that month. 

.: 5%TOTAL: CASH FLOW= 90€  ROI =7.73%As I looking for at least 100€ Cash Flow or ROI=10%, I will offer 55.000€, that means Cash Flow= 103€ and ROI= 8.31%All your comments are wellcome!!

Also......with this type of rental amount you will have a big cash flow amount.  

And then the few properties that seem like they may provide cash flow are mostly C-class. 

Now from what I remember the equation goes as follows, Cash Flow / (1+ Discount Rate) ^ Time.

My goal is to obtain 2 more cash flowing properties in the near future.

I'm planning to buy rental properties and hold them for positive cash flow.

Could cash flow okay but what are your long-term plans for the park? 

The monthly rent minus all of these expenses is your cash flow.

I strongly advise you base your decision on the 2016 cash flow of $800/month.
