Portugal Golden Visa Real Estate Investment choices

Hi All! We are applying for Portugal’s Golden Visa Via real Estate Investment. Curious if there are any thoughts or first hand experiences on which cities are most promising for rental income and or future price appreciation.

We live in the Silver Coast area (Caldas da Rainha) and see a good influx of expats looking for properties. The area is known for moderate weather (as in not too hot in Summer), less expensive than the South and still close to Lisbon airport (50 minutes). Tourism is picking up again, great golf courts around, great surfing spots etc… Still genuine and authentic and a growing community of foreigners who wish to integrate and particpate in the community. Some places: Obidos, Caldas Da Rainha, Sao Martino, Ericeira, Nazare, Alcobaça etc… We purchased a duplex in the historic center of Caldas Da Rainha 2 years ago, now looking to sell and move a bit more inland towards Tomar for a change of scenery.
