Be very careful about buying a static.
My parents had one in the same area. Don't get me wrong, it was a nice place to go for the four or five years we had it, but it is a licence to throw your money away.
First, ground rent. Started at 500 quid a year, within 4 yrs that was 2200 quid - and there is nothing you can do about it.
Obviously the purchase can set you back anything from 20-50k for a start. Then they lose value the same as a car. The park owners also have it written into contracts that you have to keep them below a certain age, they also write in you can only sell it to them, again, at a ridiculously low fee.
It got to the stage it was costing my mum and dad £90 a week just to keep it, whether they used it or not. It's not a nice feeling sitting at work thinking, I didnt go last week or this week - thats nearly £200 down the drain !.
Then you have the practicalities. As I say, for 4 yrs it was fantastic. However, the problem is the good old british weather (and lack of sea !). The first few years are lovely, as,when it is cloudy / raining you can do Wookey / Cheddar, Clovelly, Watchet, even go further afield like Lyme Regis etc...
There comes a point when you have done them all, and you travel down there to sit in a caravan doing a jigsaw when it rains.
honestly, SERIOUSLY look into it - it isn't the paradise it seems.
Now, what we did was bought an apartment in Spain for CHEAPER than a caravan. The weather is always hot, I can always go in the swimming pool, or sea. I relax most the time I am there, and you have a whole country to explore.
And the good thing, we bought whilst Spain are in recession (still are). When we do get bored, we can sell it and not make any loss (won't make much profit, their tax laws are more strict than ours - but we won't lose (already gone up 10k) and it will basically mean we would have had free holidays for the duration.
Wit the mortgage, and ALL running costs it is around £2200 per year, so basically, if we go once, it is paying for itself as that is cheaper than a two week holiday ! - any more is a bonus !
Up to you, but hope this helps
