回複：請教如此告房東贏麵多少?

I think 不贏不收費的律師 mostly take those big case such as sexual harrasement or bodily injuries.
Your case may not be strong enough to get a lots of money even if you win. So the attorneys probably won't get paid much.
Maybe you should consider the court for small claims.
Or hire an attorney and make the apt owners pay for the attorney fees if you win.
Good Luck
