"Help! We want to buy our dream home, but need to sell our house first. What do we do?"
At RE/MAX In Motion we use the ‘Sale of Home Contingency' in the best interest 
of our clients and we know how important it is to make sure that our clients are not at risk.
When a sale of home contingency is properly written, explained, negotiated, and advocated for, with the right terms, it can be a WIN/WIN for both buyer and seller. Most offers with this contingency make it to a successful closing.
New policies at the Ithaca NY Board of REALTORS have made it possible for sellers' properties to remain in ‘active' status even with a sale of home contingency offer in place. This means continued exposure of your property. This allows buyers to continue to see your property & make purchasing decisions. 
If this makes sense for you, ask your REALTOR.
At RE/MAX we know how important the next chapter of your life is.
Hmmm, here in Maryland our MLS requires you to put the home in contract/KO status. If you leave it active you face a heavy fine. I can see both sides of the issue. On the one hand, you want to get as much exposure as possible. On the other hand, if I'm a buyer agent I would be pretty upset, after the fact, to find out there was already a contract on the home. Case in point. I take my buyer in, they get excited and write an offer. The 1st buyer really wants to proceed and are able to waive their financing contingency. So all the work and emotion put into the offer is for nothing. Not so bad if they know from the start there is another contract. I guess it's all a matter of when it is disclosed.
