On a signed contract
3% / 2% / 1.5%, combined cap $24,999
3% on the first $250,000, 2% from $250,000 to $500,000, 1.5% above $500,000. A $500,000 contract pays $12,500. At $1,000,000, the combined $24,999 cap with the owner's $7,500 fee brings the builder side to $17,499. Half at signing, half at construction start. Nothing at closing.
When a co-op is already in the deal
One pot, near 3% total
If a buyer's agent commission is already payable, the Grandmark fee and the commission share one acquisition pot. The split is stated in the disclosure before the introduction. No stacked surprises.
