The only thing in that remains constant in RE: to customs is changes.Bid the job as per plan,get the contract and do a walk through.Explain that what you discuss will be wired as such and any changes after wired will be expensive.Write up all changes and charge applicably.From experience once you have it wired the HO will make changes,it`s just what happens.That`s where the real profit comes in to play.
You can`t per sq. ft a custom home you will take a huge bath on it if you try.Bid the devices, cans,service etc.I like to box the home before doing a walk through.That way the Ho can see a box and you can tell them what it will do/control.That`s when I lay the low down, now it has no wires in it once it`s wired the price of poker goes up.I`ve seen big customs go triple of what the original bid was after extras.
Oh the extras usually continue in trim stage too,Once the drywall is complete they usually come up with things they never considered.Like, what my theaters projector needs a receptacle ???Or you`ve wired the kitchen as per plan and now there are warming drawers,insta hots etc.I just giggle and add it up.
