not heard of a building broker
is that a broker that sells buildings.
or a broker that does building finance
or a broker that builds investments
What accumulator is refering to is a broker just like a mortgage broker.
Geoff Doidge from the Reno Kings is interviewd on his first solo development (just recently I might add) It is a good read, and in relation to the broker, he says:
"The broker found me a builder, one that shaved off $200,000 off my previous quotes: problems solved" When Geoff is talking about the broker, he says "As he explained at the time, You tell me what you want to pay for and I'll find you a builder"
