Local Insight
This 1930s Old San Juan condo is priced aggressively for the neighborhood, but the lack of square footage data is a red flag—you need to see the actual unit size before comparing it to comps, since Old San Juan layouts can vary wildly. The $100 monthly HOA is refreshingly low for a historic building, though you'll want to confirm what's actually covered and whether there are any special assessments pending on a structure this old. Being in flood zone X works in your favor for insurance costs, and the 360° tour suggests decent transparency, but inspect carefully for moisture issues and verify that any recent updates (plumbing, electrical) meet current code.
