Interesting topic, I'll put my twist on it.
In Sept 2010, before we had a park home, we were going on holiday to Skegness.
I looked on the internet for park homes on our way, and others within distance of having a look at whilst there.
On the way we called into a park we looked at about 3 years earlier but didnt like. Different day 2010, nice and sunny, we liked the site and noted their were 9 units for sale (out of 100)
After the hols, I arrange to go and have a look with a rep from the management company.
One I saw was "it", so I mentioned could we bring our 2 cats. Yes, on proviso when they die we cannot replace, which was ok with us.
Next day I phoned the management office to arrange next step and just mentioned we were ok with taking cats but not replacing when they die.
We were then told the rules had recently changed at request of the residents association - dogs allowed but no cats.
I wrote to them, offering to put gates on the front of the unit so the plot would be enclosed, the other 3 sides were enclosed, and explaining one of the cats had cancer and according to the vet not long to live (he lasted a further 10 months, and the other was so timid if you said boo to her you wouldnt see her for a week.
The answer was still no.
Neither of them attempt to get out of the garden in the home we lived, neither when we did move into a park home and put p a temp fence.
There was 9 units for sale out of 100, Nine percent is a large proportion of units for sale, here was someone willing to buy one, but rules could not be relaxed. That unit we liked took at LEAST another 10 .months to sell.
The site we moved on to also has a no pets (cats dogs rabbits) policy but the owner relaxed the rules so that we can fence our cat in (and he gets 10%), but that sounds sensible in these difficult times.
