So let's be clear.
Prospect cancels and does not call you... great
send a text message saying "we have this lovely unit that you might like, when are you stopping by"
You need to see what the groundwork was before you set the appointment. That's your issue. You need to lead generate, make contacts, set appointments and double book. The more filled you appointment book is the better you are.
I fill my entire afternoon with appointments, and lead generate all morning.
about lead generation: I can not state this loud enough, QUALIFY them, for example, I don't ask how good is your credit score, I ask "what is your credit score number". don't ask if they have ever been evicted, ask "has anyone ever taken you to court beside like me for speeding tickets" then you can gently get into the eviction question ( I accept people that have been evicted, I just screen why it happened and divorces seem to be a big reason )
