Ok, I am a newbie but I have been around real estate for years. I agree with those that say it is not our job to calculate payments and such for our clients. For starters, they should already know these details as we should only be working with qualified buyers and not lookers. Something many agents need to learn. Not too mention, there are so many options & factors when dealing with mortgages. Why sell yourself short and lose a sale for mis-calculation a payment. For example, my personal home is for sale currently, and someone could pick it up for $1100 month or $2400 a month. You can see the difference.
As for the 6 copies, my broker is having me pick 6 up tonight to take to my client. I guess everyone has their own ways. I'll do it their way though as they have been around longer than I've been alive:))
