It depends on how much you have to make. I charge $5.00 a pane and up. Iam 50 miles north of San francisco. At $4.00 a pane x 135 panes= $540.00 -
$300.00= $240.00 profit. Ask yourself would that be enough profit. $4.00 a pane is the cheapest I would go. You could always buy a tucker pole for the outside and lease DI tanks from Culligan. You would then have the equipment for many more condos.
