To build a community you need a lot of trust in each other.Investors mostly work alone for this reason.Developers already have their communities on their books fighting over registation,prelaunch,launch discounts etc.
Bringing 400 investors together would mean turmoil,400 times the fighting,400 times the greed.

Believe it or not but developers would love it.Prices would go up so fast through greed,then no one could sell.

Prelaunchs and discounts are only developers advertising their next tower.
Many times I've purchased at the same price as a bulk buyer months after launch.

Investors who work alone will keep the market stable for longer and still make a good profit.

1 GOOD QUESTION IS CAN PRICES BE STALLED PER SQ/FT.RENTS CAN ONLY SEE A CERTAIN INCREASE YEARLY.DO YOU THINK THAT SALES PROFITS MAY ONLY ALLOW A CERTAIN % ON TOP OF PURCHASE PRICES.WHAT SENSE WOULD DISCOUNTS MAKE THEN.

I really think that working alone will keep us happier longer.
