Golden visa timeline question

Hi. I was told that in order to buy in high density areas I had to determine my type of investment and sign a reservation letter by July 1st? (I could change my mind later) Was this the case and if so has this requirement been recently waived? Thank you very much

I think there was a deadline of July 1st for online submission of the application which has changed. I would appreciate confirmation of this and when this was changed.

Thank you

I think now they extended the Golden Visa to Dec 31 2021 to buy in areas of Lisbon and high density areas
