I don't think I'd have any interest in every buying a house if it weren't for the insane tax deductions for mortgage interest. Why be stuck in one house when your living situation changes over time (new kids, kids get bigger, kids move away, job changes).
The biggest issue I found with owning is that the equity doesn't build up fast enough at the beginning (with a 30-year mortgage), so if you sell after 10 years the costs pile up to the point that you have almost no net proceeds (5% commission, survey/title/transfer tax/inspections, plus prorated property taxes). A 200K property could easily cost you 20K or more to sell.
The best thing you could do is to put as much down as you can, on as cheap of a property as you can (condo, townhouse), then send in additional principal payments so that you could pay it off in 6 - 10 years. Then you can either put away extra savings after that, or move into a slightly more expensive place (about 60K more than your current house), and start the 6 year cycle over again.
