If the home is being offered for sale, a cash offer will help the process go faster, because there is no waiting for the financing to go through as long as buyer and seller are in agreement. You would still want to consider having the home inspected and also the title company will run a title search to make sure there are no liens or judgments on the property. You will also want to consider having the home insured. With that it could take about 2 - 3 weeks to close on the home considering everything goes smooth.
