Also I see that you have a Charlotte phone number .

  :)I like that there's an actual name on the tag with an 801 phone number. 

Having spent years buying courthouse step properties my small commercial bank is all set up to produce cashiers cheques for me simple phone call

You will most likely not get a phone number.Use their address to look them up in the white pages.

In either scenario I do not provide any appliances, reason is that it lessens the chance of receive a middle of the night phone call because the appliance broke or hiring repairmen for that matter.  

The potential problem that could arise is that your buyer could have an issue, call contractor, have the contractor fix it, and then tell the contractor to send you the bill -- all without your input.While -- in my opinion -- there are plenty of situations where it's reasonable that you foot the bill for a renovation item that wasn't done correctly, you would much rather those phone calls go through you than directly to the contractor. 

Am I just waiting for a phone call?

It probably wasn't the best financial move but with the phone starting to ring I had to make a decision and a company came along that was manageable at best. 

Phone call with a follow-up letter that leaves the door open perhaps?

I know mail outs is the most common but is there anyway to obtain actual phone numbers ?
