The thought of owning a campsite has the advantages listed above. However the decision to buy a campsite needs some special thoughts.
First of all find a place that you can be happy with for the long term. Some look great at first, but once you get in, you find things you don't like. So make sure to list your wants and needs. And do not compromise. Then if possible stay there for a few months before you buy. And be sure to talk to lots of owners and to other renters.
My advice is to ONLY buy in a well established and built out community. Many development campground communities start off small and as they sell off they grow into future "phases". In order to attract customers, they need to invest heavily into landscaping and facilities...clubhouse, laundry, activity center, pools, tennis courts, golf course, etc. Because of the high initial cost, the pressure to sell is very high. And many fail in the first year or so. If you bought one of those first lots, you might be in jeopardy of losing your investment, if the developer goes bankrupt. If he sells the development in time, you have hope. But it seems like most new developments change hands at least three times before they really start to catch hold.
If you can buy into a developer community that has a broad ownership base that is much better to guarantee that your investment is protected. Make sure there is a majority of sites that are owned. That helps ensure the developer is now operating in the black and that the upfront expenses are paid.
Special assessments and economies of scale...As the community matures there are needs for improvements and repairs. If these costs are expensive (road repairs, water, sewer systems, pools, fire hydrants, sidewalks, etc.), these costs must be shared by the lot owners. If there is a $50,000 assessment, it cost $5000 each to 10 owners. Or $500 each to 100 owners. Or $100 to 500 owners. So the more owners the less cost burden on the individual owner.
The HOA rules/restrictions. They can be very restrictive. Make sure you can live with them. But also make sure they meet you needs. Do they limit certain types of campers? No Popups? No travel trailers less than 25 feet? No RV's older than 10 years? Over 55 community? Your lot needs to be maintained within certain standards? If not then expect a professional landscape service to be called by the management, and you will be billed. These are all very restrictive. But they make for a very well maintained, pleasing and value investment. Are visitors limited? Is there an additional charge for visitors? Is there parking available for visitors?
What is the concentration of park models, Modulars homes, permanent RV's, and transient RV's. Does this meet your needs. For now...and in the future. For whatever you might want to do with your site.
The management...Is it owner management? Or is it developer management? Is there a full time paid park manager? Is there a Board of directors? Developer or ownership. Is there a financial manager? An architectural committee? A permit process for major improvements or alterations? How much money does the association have on hand? In a reserve fund? What are annual expenses, and revenues. Do they issue an annual report?
What about easements and rights of way. If you buy off the lake is there public lake access? Are the facilities large enough to handle the population at peak times?
Do they let you rent your property when you are not using it? Will they help you rent it? Where they take the rental headache on, for a fee?
In order to really find the answers to all these questions , this is why it is best to rent a spot in the place you think may have the potential for you to buy. And talk to as many renters and owners as you can. And if you can meet with the managers or members of the board, that would be good too. Some times a poolside chat can tell you a lot.
Hope this helps
