Hi Cupcake and welcome to the forum,
Some parks use a specialist company for their part exchange deals and others buy your home in themselves.
They all seem to work in a similar way and that is to get two or more valuations from an Estate Agent taking the mean average, less a percentage. Click through to this company who are very active within the park home industry http://www.arcpropertygroup.co.uk
Some also pay your legal costs. There would of course be no Estate Fees. All of this you would need to take into consideration when you are given a price. There is also the advantage of not having to run the risk of a chain breaking down and having to start to find a buyer all over again.
Perhaps it could be a good idea to get a couple of valuations from Estate Agents yourself before you go down this route. This would then give you something to compare.
Good luck and let us know how you get on. I'm sure there would be others very interested.
Regards
Ed.
