FAB is in a very very high price area even for Southern UK, not so much Farnborough itself but neighbouring Fleet Camberley and farnham are very pricey indeed as are the smaller villages like Yateley and Hartley Wintney and Badshot Lea
Basingstoke isnt a bad idea at all or Hook neither cheap but more affordable esp Basingstoke and only 15 mins buy train to FAB and the same by car unless you are in rush hour . Aldershot is alot cheaper but although not everyones favourite palce there are alot of new developemnts on the edge of the town which would work well for rentalss
there are number of serviced apartments that ahve been developed locally pretty much for the FAB crew trade
justa few ideas from a local
