In some countries you need to set up an appointment in advance.

I'm really happy to hear you have an appointment and should get some professional advice! 

In fact, we ask them to confirm they've read the standards before confirming the appointment.

Our agent was rushing us because she said she had an appointment.

I would say probably about 5-7 appointments per contract. ( this is not hard numbers simply a guesstimate.)  

Since an executor/personal representative has not been appointed by the court and no Trust is in place, there is no one who can sign for the deceased. 

I called warranty service the next morning as soon as they opened  and made an appointment for Monday. 

Set an appointment, have a list of questions ready, and jot down the answers.

You might talk with a real estate/estate attorney and see if it's possible to open a probate, have a Personal Representative appointed and obtain an order from the court authorizing the sale of the property by the PR with the proceeds being deposited into the registry of the court for later distribution when all the heirs are identified. 

We started playing around with AI Callers for inbound lead appointment setting, the results are pretty encouraging.
