I live not far from Crawley op, I guess about twenty mins drive and I’d be really cautious about buying there right now, I’d give it at least a couple of months before I do, because there could be a crash.
Crawley was even discussed in the Houses of Parliament. Gatwick is basically all but shut, a few flights a day, and many people who live in Crawley rely on the airport, so from hotels who take travellers, to transport companies to supplies to the airport. The lot.
Unless something changes soon they are predicting mass unemployment, And when that happens there is a knock on effect, because folks have no money to spend in shops or restaurants etc. Then they close too,
Airlines are pulling out of the airport, Virgin I think was the first. Ba likely next, don’t get me wrong I think the airport will survive, but it will take time and could become a very different animal.
As said, the area could be devastated, if you can hold off, you should.
