We exchanged phone numbers 'cause it was very important. For someone that was about to begin looking for a house for me soon, I needed to have his mobile number, and he needed to have mine as well.
From time to time, I can be calling him to get details concerning the house hunt. If he'd found one, if he was close to finding one, or he was still searching.
Yes, I needed to be getting information regarding these things considering how fast it would take him to find the kind of duplex I wanted...
And he can be calling me as well to be giving me updates about how the house hunt was going. Once he'd found one, he could call me immediately to inform me.
That's why we had to exchange phone numbers. After that, we talked about agent fees and all that, and we agreed on a particular amount.
All these would be paid after he'd found the house...a lot of money would be spent.
