Mike is right that you'll have more certainty in looking at resale options as you can be in better control on the moving dates. In addition you are also likely able to secure bridging loan for the downpayment with proof of sale of your existing unit, unless your application for loan is rejected by the banks for certain reasons.
I will need to know more details about your situation and needs in order to assist you better. My dedicated team of salesperson have met with countless of homeowners like you sitting on the fence unable to make a decision which way to go and after talking to them and understanding them better, we are able to assist them in their decision making process. It may not end up as a sale, but we end up making another friend whom we believe in building lasting relationships.
Let us know what your concerns are and we will be better equipped to assist you.
