Landscape updates to create an outdoor dining, grilling, and firepit area.

I'd also ask the HOA who they recommend for landscaping, surely there is common area that they maintain

Otherwise, drive for dollars, ask landscaping companies, UPS/USPS/FedEx drivers, etc.

Basically, the analysis process is the same, however, you might need to pay for water, sewer, trash, and landscaping depending on your area. 

I know that per the lease landscaping maintenance will be maintained by the landlord, outside of the first year I dont know if its still the same company being used and/or the same rate.

To answer more specifically your question about costs, there are a lot of expenses that you'd want to watch out for including cost of goods sold (if they have a store or propane), utilities (a HUGE percentage of expenses for a park), payroll, maintenance, landscaping, CC fees, well and septic testing and maintenance, insurance, taxes, licensing and fees, etc.Good luck and let me know if you have any pinpointed questions - happy to help.
