Best way to manage selling/buying at same time

[Ethan Bennett]

What is a good way to sell a house & buy another without having to move into an apt? Are there clauses you can put into a contract that will allow you to stay at your house until the next goes through? Ideally we would already have another house in the works at the same time of sale.

I am trying to avoid renting an apt until another house is finalized.
