With today's current market trend is it wise to have backup plans?

[Suzi Clue]

The way housing has been plunging, it's really hard to make a sale now adays. Clients are asking for percentages of the sales and it's really cutting into the bottom line now. Every week i visit this website that display the housing trend and it keeps sinking to new lows in my market (Los angeles) [LINK REMOVED BY ADMIN] It looks like there's no end to this downward spiral.

Any suggesting on what to do while the market is spiraling downward?
