Really! No joke.
Ideal if your have some land and you cannot get planning permission to build conventional homes on it or if you get the opportunity to buy an odd piece of land cheaply. It does not matter where it is located as some parks are clearly opportune.
Better still if you already have a campsite or static caravan park.
Once you have some land you can get concrete for the base.
Next go to a mobile home show where they exhibit the latest show homes and negotiate to buy an exhibition home. Better still if you can get a manufacturer to 'donate' a home at his cost on the premise that you will buy more homes as the park takes off.
Install the home on the slab.
Place an advert in a Park Homes publication along the lines of:-
'Have security, peace of mind and a delightful living environment at our premier residential park home complex.
Moving to a residential park can mean swapping urban life for a peaceful place in the country and becoming part of a friendly, like-minded community.
Downsizing to a park home can release capital in your bricks-and-mortar to fund your retirement.
There’s a great choice of park home styles and designs, and they can be supplied fully carpeted and furnished – so that’s another expense taken care of.
Benefit too from the low maintenance and running costs that come with the modern well equipped park home.'
You need to have also done the following.
Get planning permission.
Obtain a residential site licence from the local authorities and develop your site in accordance with the licensing requirements. These include site lighting, road widths, boundaries, density of homes, provision of proper utilities such as water supplies, electricity, drainage and much more.

The water supply above is probably not quite as required.
Read and understand the Mobile Homes act and understand your legal obligations to your tenants. The legal aspects are mandatory but as your park will attract residents who are advancing in years, you have a duty of care to treat your tennants fairly and repectfully. Your competency as a park owner will be scrutinised.
Produce site rules and lodge these with the local licencing authority.
Learn the NCC 501 code of practice and the necessary requirements for siting and maintaining a mobile home.
Ensure you can look after the areas of the park that are your responsibility. Cutting grass, maintaining boundaries and street lighting etc will require additional resources.
Register as a Goldshield site.
