Condo board won't let us in. Please help.

We have submitted the package to the condo board. They are refusing to exercise their right of first refusal. The managing agent says we don't have enough income but we have enough assets to buy the property with lots left over. We decided to go the mortgage route because it made more financial sense. We have had no communication with the board, only the managing agent. We think the statements about income are a ruse and what they really don't like is we have several kids. When we first applied the managing agent asked how many kids would be in each bedroom. Is there anything we can do? We didn't think this sort of thing would happen in a condo. Thanks to all in advance.
