What you could do is put a contingency clause in your contract. Depending on where you are located your local Realtor will have a contract that may have that clause in it already. It allows you to place your home on the market for sale but, put in an offer for another home under the "contingency" your home is going to be sold. A lot of times when someone puts that contingency in their contract they will also put "first right of refusal" in there as well. This would allow other offers to come in on the home you are wanting to purchase but, giving first option on the property. If someone came in with a full price offer cash in hand or could close immediately they would ask you if you wanted to purchase at that time regardless of your home being sold. There are many options when you have a home to sell. If you need more information feel free to email me.
