My mum has a caravan located on a caravan park. She notified them by email on 1st Jan 2022 that she wanted to sell it. The caravan must have first refusal which is in their t&cs. We have chased them and chased them for a valuation and when I called their cafe on their site the lady said she was the owners wife and he had covid but he would call me. No call received. The fees are due by 31st Jan each year. They waited until this date and called to offer her £300. Although it is old they are selling older ones on their site for £8995 in worse condition. The new fridge in there alone is worth £150 so she called to say she would be collecting it and they upped their offer to £400. I can’t help but feel that they have royally done her over. Either accept the £400 or pay the £3000+ for the annual fees. She only left it this late as my dad died and we’ve been waiting for probate as they weren’t married and dealing with lots of other finances. Anyway, do we have any options or is it best to walk away knowing they won’t get another penny from her? Thank you for any advice.
