Zakat question relating to investments

Assalamu’alaykum.

My mum has invested a considerable amount of money into different portfolios and I need to know if zakat is due on all the investments

  1. A property Development project
  2. ESE capital strategic land acquisition
  3. Cur8 capital

She has invested money into each

  • The property development project she invested over £30,000. It is in process of being developed, not habitable at the moment. The value of her investment is estimated to go up 15% on completion but not for another 6 months. Does she owe zakat on the £30,000 she invested?

  • ESE Capital. This company bought strategic land and hopes to get planning to build a wellness and health centre. We have no access to cash if we wanted it back etc. My mum invested over £10,000 here. It is estimated to go up 50%. Planning requests so far have been rejected so a new proposal is being made. Is full zakat due on this?

  • cur8 capital. My mum invested approximately £20,000 here in startups. Is zakat due on this?

Apologies if this has been covered elsewhere I could not find it. I tried using cur8 zakat calculator but it was unfortunately not helpful with this
