Using investment fund units as mortgage collateral

Hi all,

Looking to acquire GV through the fund route, then once my GV is approved, use the fund units as collateral for a mortgage on a property in Lisbon to live in. Anyone have any idea if this is possible, and if so, which banks are open to this?

I’m aware that it’s possible for foreigners to get standard mortgages without needing any additional collateral, however my proof of salary may not be sufficient as my income is irregular, plus they may offer a better loan-to-value ratio with additional collateral.

Cheers!
