Condition Rating
Good
Despite being built in 1969, the property has undergone significant recent updates, including new flooring, interior paint, and an upgraded terrace, as stated in the description and confirmed by the images. The kitchen features modern dark cabinetry, light countertops, and stainless steel appliances, appearing recently renovated. Bathrooms also show updated vanities, tiling, and fixtures. While the core systems (HVAC, plumbing, electrical) are not explicitly detailed as new, the visible areas are move-in ready and aesthetically pleasing, aligning with a 'Good' condition rating where major systems are functional and within expected lifespan, and significant components have been updated within the last 5-15 years.

Age of Core Structure: Built in 1969, the property's underlying systems (e.g., plumbing, electrical, HVAC) may still be original or older, potentially requiring future maintenance or upgrades not covered by recent cosmetic updates.
Monthly Association Fees: The property incurs a $300 monthly association fee, adding to the overall cost of homeownership.
Limited Specifics on System Updates: While cosmetic updates are highlighted (flooring, paint, terrace), the description lacks detail on major system upgrades (e.g., roof, windows, HVAC, kitchen appliances), which could be a concern for a 1969 build.
