For a builder, every month a home sits is margin walking out the door: carrying costs, interest and momentum you can't get back. For an investor, it's the same math on the other side. Time in the deal is return out of the deal. Neither of you needs an agent who plants a sign and waits.
You need a marketing operation engineered to move property fast and at full value, and a partner who speaks your language. I talk basis, draw schedules, carrying costs, ARV, cap rates and price per square foot, not just granite and crown molding.
