I am wondering how to sale a prewire and install to contractors. How much should I charge and how much does an alarm system being in a house raise the value of the house? Also what should I tell the contractor and realtor on how this would benefit them on getting the house sold. The one contractor I have talked to told me he liked the idea but dosnt want to get too much cost in the house and would like to just have the realtor mention it to the buyer. Of course I think having the system in the house is better when the buyer moves in because then they have it there to look at and would want it to work and then be inclined to call me and activate it. I would like some techniques or ideas on wording or even some statistics. Thank you.
