I am a condo owner in a condo that's been really restrictive on rental units. I work for the government and live overseas. My renter just left and the current house rules allow me to rent my unit for another 1.5 years (36 months max from the time the rental threshold was reached in december 2009). It appears that the condo board is considering changing the house rules over this weekend to keep me from being able to re-rent. I understand that house rules can be changed without a full vote of the membership. My question is: do I have legal grounds to sue for damages if they're changing the rules midstream and causing me undue financial hardship as a result?
