Okay, I used to live in Fleet and can recommend it, with two words of warning. All of the schools are good and they are all over-subscribed, to the extent that one of the housing estates at the end of the town are sending children through to Aldershot. And, there is a lot of building planned both for Fleet and between Fleet and Hartley Wintney. They will essentially end up joined them together through Church Crookham, if they keep building as they have been. Fleet is also very expensive and the station doesn't have parking space after 8AM.
If your husband needs to get to Portsmouth you are going to want the A3 as a preferred route, I believe.
Somebody said there wasn't, but there is a fast train link from Hartley Wintney. Winchfield station is 2 mins by car outside of Hartley Wintney and is one station up from Fleet. About 50 mins to London Waterloo give or take, which is faster than the train from Camberley.
I wouldn't choose Camberly myself, or Farnborough or Aldershot. And as nice as Hartley Wintney is, it has some problems around schooling. This is straight from one of my old neighbours who is a school teacher in Fleet.
If you want superfast train to London and easy access to the A3, I'd suggest Guildford and the surrounding villages, but they are again pricey housewise.
I'd also suggest you take a look at Odiham. Very like Hartley Wintney but no A30 roaring through the middle of it, station close by at Hook and access to the M3 from junction 5.
Happy house hunting.
