Before even thinking about purchasing a vacation rental I would check the rental rates in the area.Also the location it's in will be a really good factor in how much you can get for rental rates.Who will be showing the house, cleaning after guests leave, maintaining, marketing?

Being licensed can be expensive to maintain if you do not plan to use it to generate income.  

I’m just trying to understand the average costs of maintaining the property.

They had redone the roads, keep the grounds maintained, clean bathrooms, a big meeting room/building for parties, a fishing dock (although it was on dry land at the time due to drought),  even rental spots for RVs were nicer so they pulled an upper end crowd.From what I've seen in my immediate area (and I've researched it), if you have cabins at a trailer park rent pretty decently.  

The upside is that someone else maintains the building, so you can do it with minimal direct involvement.

Monthly rents: APT 1 $900 & apt 2 @1095.Total rent 1995-30 garbage-25 water-100 insurance -120 repairs/ maintain-100 vac-970 mort/ taxesCash flow of $650 x 12= 7800.    7800/41541= 18.5% ROII plan on managing and lawn care on my own if I do end up outsourcing it the number would be: -199 management {10%}-66 lawn careCash flow +385 x12= 4620        4620/41541 = 11.5 % ROISo with self managing the ROI is great not so good if I outsource management Let me kno what think of these numbers!

Here are the details:Purchase price: 55,000$Rehab: 5000$Currently rented:  900$ per month (400 and 500 each side)Expenses:  Approx 400$ (includes property tax, insurance, water bill, property management - 8%, yard maintainance and 10% of rent as rainy day fund)Financing:I will buy this property with the HELOC on my home.  

That way I could quit my 9-5 job and basically maintain these places and collect the money as my job. 

And while they are certainly motivated to provide a good service to maintain their reputation, you have to understand that their bottom line, not yours, is the primary concern of their operation.  

The house was listed low because the owner can no longer maintain the property and is not of right mind so she has an attorney handling the sale.
