We have 5 doors with another property manager and I'm on the phone with them from twice a month to twice a day resolving issues.

I have even spent 30 minutes on the phone with several people explaining the process. 

Someone didn't hang up the phone and actually IS interested in selling (the first time this has happened so far). the only thing is the home is a mobile home located in a senior community.

Requests for loans were most often made over the phone or in person with potential borrowers paying us a visit at our offices.

Take into account the travel time, phone / video time, mistakes along with all the other economic factors.

Would you just start cold calling in the phone book?

I don't agree that because someone answers the phone means that they are bad.

Communication - Text, email and phone.

Depending on the level of flip you're doing for, RTA cabinets are great quick, cheap options for kitchen and bath cabinets.I always talk with contractors and add any sources to my phone.

That's a "bad phone call" to get.
