We're buying a house - it's a "nice" house, convenient for work, but not our "dream" house (which we currently can't afford - at least not in the region we're in). We plan to stay in this house for 5-7 years, during which our careers will hopefully continue to go up, and then move to a forever home. In those 5-7 years, we will be overpaying our mortgage, and I plan to save about 50k in that time that shall go into the new home.
Is that a viable plan? Did you ever buy a house you knew you were staying in only a few years?
