Yes, you can depending on several factors. Are you able to financially handle the burden of 2 mortgages? It is vey unlikely that a seller would remove their home from the market contingent on you selling your home. They are in the same boat as you are! If you had a firm contract on your home that was pending sale, sometimes a seller will accept the successful closing of your home on XX-XX-XX date as a contingency to the buying of their home, as long as the closing date was not too far off. In these days, it is definitely a buyers market and sellers need to recognize that. There are going to be many times when a buyer will want to "low ball" an offer on a home. They want to "test the waters" and see what they can get. The sellers first instinct may be to get offended, as their home and it's value is of course, very important and emotional to them. Everyone has to take a step back. Get objective, be patient, try to compromise, and find common areas both parties are willing to compromise on. You may be surprised that everyone will finally come close to terms on price and conditions.
