Advice Needed on Condo project

[Skip Reath]

Currently own 11 condos in South Chicago in a 35 unit complex. Am only allowed to rent 7 of my 11 units.(HOA restriction) Have 4 units that need rehab but I'm hesitate to do so as I can't rent nor easily sell anymore units. HOA has lots of delinquencies and lost FHA financing option. Have to keep my HOA assessments current or lose the right to rent the 7 units. So is there anyway to get rid of the 4 non-performing units as the taxes and assessments are burdensome?
