When does the buyer get Keys?
Are your buyers new to Arizona? Best to let them know early in the process, that Arizona is an Escrow state.
In some states, possession of the property is turned over after funds are transferred. In an escrow state, the additional step of recordation is required, before legal transfer has been completed. If your buyers are from an abstract state like, say New York State, they may wonder why they cannot get their keys at the signing table, and may be disappointed and upset.
