I would definitely contact the condo association for more detail on the ratio of owner occupied to investor properties within the condominium. Lenders do require that information to process a loan and actually, in my experience, the association will make certain a buyer intends to occupy the property -- so they assure there isn't an overage of rental units within the condominium.
Another point, if the condo docs reveal a high number of defaults (either foreclosures or short-sales) this info can cause problems when the lender is considering approving a loan.
I'm available to help with any other information you are seeking.
