While I agree with my colleagues to a point, which is better is dependant on how the original homeowner kept up with the maintenance of the house. Likewise, I have seen newer (5-6years) homes and condos where the owners cared nothing about maintenance or the upkeep and trust me they had maintenance issues.
One of the brokers pointed out something very important, during the period of 2003-2006. The issue was the cinderblock being used. Some developers knowing cut corners and did not use a weatherproof exterior cinderblock and as a result some home built in this period have moisture issue. This can be dealt with by having the cinderblock sealed at considerable expense. However, personally as a home buyer I would be worried about potential hidden mold and if it were my purchase I would get an inferred structural inspection before purchasing a home or condo built with cinderblock between 2003-2006.
Nothing replaces the expertise of a good home inspection!
