If you have a house to sell it is important that you move ahead with that sales process as quickly as possible. While your home is being marketed we can proceed with planning, drawings, and selections. Once your house is sold we can begin building.
In terms of matching the closing dates you could seek a long (4 months +/-) closing for your existing house or arrange for rental accommodations for the interim. Sometimes we can point you to a helpful solution – be sure to ask.
