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.  

Hello, I have a townhouse as a rental property and I pay the HOA which includes water, snow, and landscaping, and tenants pay their monthly rental plus electricity and gas.My HOA has a program called TAP(Tenant Administration Program), and they collect $100/year.

@Ben M.Have the landscaper send you pictures every time they mow.

@Rajan SainiFrom the beginning if time is a factor; hire a bookkeeper, hire landscapers, find good handyman and find a good virtual assistant for tasks that can be completed online like posting apartments for rent.

Next on the list is exterior paint, wood repair, new roof due to a hail storm... and landscaping.

Up until a few years ago, I worked different construction-type jobs from landscaping to building scaffold for commercial sites, so I still have a lot of good connections in that world, like a friend who is a lead at a painting company, one who does framing, a couple guys at "1-800-Got-Junk?" 

Although my personal experience with owning a few rentals there has been overwhelmingly positive mind are in Summerlin in very nice neighborhoods and with tax's so low and quality A class tenants no real maintenance other than normal things that might wear out but when you take stucco  tile roof and desert landscape along with some of hte lowest property tax's in the country the COC is right were we like it for conservative SAFE risk reduced rental investing.. 

There are long term leases that are dozens of pages long for long term housing that cover every item imaginable such as who is responsible for clogged drains, broken appliances, landscaping maintenance, etc. none of which  are likely to be in a short term lease.

Perhaps you could have a landscape architect come by and do an inventory and analysis report. 

Occasionally it will make sense for homeowners in a spot where accessing the line would be severely expensive & destructive, like underneath extensive concrete, buildings, expensive landscaping, etc.
