Selling Houses

Ever since we reduced the asking price on the house we have had several viewings and lots of encouraging feed back from the estate agents. The last two couples to view have both expressed an interest. Couple one have to sell their house first, they really want this house because it is on the same street as the girl's sister and they have their son's name down at the local school. Couple two have sold and are in rented accommodation. Couple one walked by on Sunday just to have a look - I was on next door's drive chatting to my neighbour when I saw them - and have phoned the estate agents a couple of times to see if we have had any interest or offers yet. In the meantime couple two are sorting out their finances and coming back for a second view. My heart says that I would like couple one to buy the house but my head says that if couple two make an offer then we have to accept it as we need to lose our mortgage as soon as possible. We are venturing out to look at some houses at the weekend because if couple two do make an offer I'm guessing they will want to move pretty quickly. I don't really enjoy all this.
