Hi @squiglet111. I live in Wycombe but bought my house nearly 7 years ago so things have changed since then and I may be a bit out of the loop.
On my estate there are two houses which sum up the market I think.
House 1: 4 bed detached on the market at £487,500. Sold within a couple of days
House 2: 3 bed mid terrace (extended from a 2 bed) on the market at £450,000. Has been on the market since April.
Personally, I think House 1 was too cheap, but House 2 is way too expensive.
So I don't think Wycombe is any different from anywhere else at the moment. If a house is marketed at the right price, then it will sell.
Either the house you looked at really is worth £330k (in which case they should probably have put it on at £340-350k) or they're not being realistic in what it's worth. I've found the house online and see that the previous listing was "offers over £330k" last year and didn't sell. Time will tell whether it's worth it or not.
What is your budget? Could you afford £330k if you wanted to? If so, could you imagine losing it to someone else? Buying a house is a minefield. I always just think "am I happy with what I've spent?" If the answer's "yes" and I've paid a bit too much, then fine, I'll live with it.
I will say though that area is key in Wycombe as there are some areas that are worth avoiding. You don't want to spend over £300k and end up being somewhere you hate!
It's definitely worth doing a drive around at a variety of times of day if you can, especially if it's around midnight on a Saturday night. That will tell you which areas to avoid.
Also, if you're on facebook, join the High Wycombe facebook group. There's over 30,000 members in the group and it would give you a bit of an idea of what the place is like. Excuse a lot of the moans and groans on there though - people are naturally negative on online forums like a local group. For every bad thing written there are probably 4 great things that no-one bothers writing about!
I like living here (I have done for 11 years now) though it is worth noting that I don't work in the town and only really go there for some shopping. My neighbourhood is very friendly though (regular events such as BBQs, Easter Egg hunts, etc) and I honestly couldn't imagine living anywhere else at the moment.
