Hi Paul,
I live in Bethesda and the NoVA area for a while now and hangar space is definitely hard to come by at a reasonable price. The question is how many days do you want to fly?
A friend just got a newly constructed hangar at Tipton KFME which is about a 40 min drive from Bethesda and perched between BWI and DCS (so you have Class B 1100' overhead), but outside the FRZ. There might be some spaces there. The price isn't bad there, but the runway is a little short for my Velocity (right now) and I think the airspace would be hectic.
I have a hangar in Culpeper VA (KCJR), which is 65 miles or 1.2 hours of driving. Built my plane there... took a long time... They may have hangar space. There is a waiting list, but from what they told me the other day, everyone they call says no when they get called. Call Neil and tell him you have a plane and need a hangar right sooner than later. $250/mo for an end hangar (versus KGAI which wants $500... more if you want it paved with electricity).
HEF isn't too bad and is about 20 miles closer than Culpeper.
FDK wanted $500 (refundable) to be on the waiting list. That got rid of the less serious. I finally made it to the top of the list, but the only way I could afford it was to share and there wasn't enough space in the hangar for the Velocity and my tools to do that... so I ended up declining and got my money back. FDK would be a good place to be IF it were available.
KGAI would be the best place. Extremely overpriced. If they had a decent hangar that I could share with someone I would ($600/mo rent). Its only 15 min from Bethesda.
Leesburg VA (KJYO) is another option. Again, its the same drive as CJR but twice the price.
That's about all I know. Good luck in your search.
