How a typical deal pays a broker
Most brokers earn a commission when the sale closes, usually a percentage of the price. It's a fair way to pay for finding a buyer or a building, but think about what it rewards.
It pays the same whether the building works for you or not. It pays a little more when the price is higher. It pays nothing if you walk away. And once the deal closes, the broker's job is done, right when the rent roll, the repairs and the loan become your problem.
