I would choose a smaller house in a better school district. Not to mention you also save commute time. 3 bedroom vs 4 bedrooms, 5 year old vs 10 year old--- as long as you have enough rooms for your family, they aren't that different. On the other hand, having your kids in better schools and saving a lot of time on the road makes huge difference.
Agree! I would also choose that smaller house in the better school district. After all, 5-year and 10-year houses are not that different...Location, location, location!
