We have our house on the market. We have had a couple look at it
several times, have even brought an architect.  It has been a week and
no word.  Shouldn't our realtor keep us informed?  Is there an
alternative to "hurry up and wait?" And, is our realtor suppose to
tell us when someone has no interest in our house and why? Thanks!

The realtor works for you. If you are unhappy with the service
provided by your realtor, get another one.

You know someone is interested when they submit an offer to buy your
house.  Your agent would then submit the offer to you.  If you have
questions call your agent - he or she works for you.

I assume that by now you have an answer from your realtor, but know
this: your realtor is legally obligated to immediately PRESENT TO YOU
any written offer to purchase your home. If that doesn't happen, they
won't bother you. You can assume there is no written offer if one has
not been presented...
