This is a fact based topic. You should have a lawyer review your documents. A condo board cannot be discriminatory in denying a potential tenant. If the potential tenant poses a physical threat to residents then they can concievably be denied, although this is not set in stone. It is hotly debated. If the tenant poses a financial risk, a Board generally can request that the tenant pay its maintenance and assessments up front for the year or full term of the proposed Lease. A denial due to bad credit can potentially be seen as discriminatory.
