<prompt> Human: Question for those wiser than I. We are house hunting and we keep coming back to the question of, do we buy something that works for us now, but we may grow out of in 3-5 years or do we buy more house than we need and plan to grow into it? The concern with buying too little house is that having say two kids may cause us to grow out of it quickly. On the other hand, we could buy more house, but we are paying more now than we really need. We could of course buy and plan to move in 5 years and go with an ARM. However, i worry about the potential of losing money due to closing costs of buyingselling twice. Any wise words?  <response>: I personally received the advice of buy the biggest house you can afford and grow into it. As a single guy I bought a 4 bedroom house and now have 2 kids and a parent in the 4 bedrooms with plans to make a basement apartment to rent out. Has worked out well so far.
