Young first time buyers will need to grow in the careers and have much higher incomes to move up. Right now the gap between entry level homes and move up homes as well move up homes and high end homes is smaller than it usually is. Combine this with low rates and for those with equity there is lots of opportunity to move up now. I have a few friends that recently moved to RSF because of this.
For young first timers count on slow appreciation, continued saving and hard work to earn that next step up. A government supported low down mortgage got you in and getting to the next level is up to you. Isnt that the way it should be?
