My husband is in the application process of a Golden Visa, and he opted for the 350k route. The properties are in Tomar and one is in the rural area (Casais), the other is in the historic zone. They qualify as they are designated as areas of rehabitalization (not sure of the exact word). Lisbon and Porto, as well as many other cities, are already saturated but lots of smaller and medium-sized city properties still qualify, and it's easy to get that designation from the local city hall. We are going through the process with the help of a lawyer, and it's not easy but we have our fingers crossed that we'll be successful.
