The council recommends
On: "Is now a good time to buy a flat in Lisbon?"
Top pick
Buy selectively for a long-term home; otherwise rent and wait
Now is a good time to buy only if you plan to live in the flat for at least 5 to 7 years and find a property priced below market comparables. Avoid speculative investing and prime tourist centers where yields are compressed. If you lack a long-term horizon or substantial down payment, rent while monitoring listing price adjustments over the next 6 to 12 months.
Runner-up
Rent in Lisbon for 6-12 months to assess market softening from tax and interest rate changes.
Wildcard
Target undervalued emerging parishes like Marvila or outer commuter hubs like Setúbal for better yields.
Best time
Act immediately if a fairly priced flat is found; otherwise evaluate listings across the next 6 to 12 months.
