When you find a property you want to buy, a lot of times it costs more than you can afford without the sale of your current home. What I want to do is list your property and find a buyer for it. Then I can write a contingency offer stating that the sale will only be final when you find a home to purchase.
(Offer suggestions such as contingencies, etc...)
Then, you and I will go out and find the perfect home for you and your family. If for some reason we don’t find you a home, we can postpone the closing or cancel it. Does that work for you?
We’ll make sure that you have another home before you sell yours, so your family doesn’t have to be homeless.
(Give them assurance and a way to step back if things did not work out for them...)
