Your normal family property (approx 1500 - 2000 ft/sq, ~1 acre land) goes for $200k - $250k. Still expensive, but doable, especially if both parents are making decent money (>= $50k/year is what I count as decent money). Less than $30k down payment brings your monthly expenses to less than $2k/mo. Exactly half price for what I'd imagine to be similar living conditions in SF Bay (albeit Bay Area public schools are probably better than NH's, though New England has very good schools).
It's clear that you're making a lot more money than I am for similar experience -- I too am less than 30 years old -- but I wonder the difference in percentage our savable income is, given the difference in costs we both pay for housing. I too wonder for others in our age and job demographic what they're able to save when living in SF Bay vs. elsewhere.
The cost of living there doesn't seem worth it to me. Heck, NE I think is too expensive! Been looking to move down to Raleigh, NC after I get married, but that's neither here nor there.
