I'm trying to learn about geran kongsi for agricultural land. Is it very risky? My family and friends told me don't even think about it.

The agent says:

Geran kongsi 4 nama ..semua mau jual.semua masih hidup.adik beradik
Maaf .bayaran kena cash ye..tak boleh loan bank.sebab geran kongsi 4 nama.semua nama setuju nak jual.semua nama masih hidup

Is it a scam?

I was thinking to buy cash deal. Borrow money from family members to do it.

Anyone have some experience in this area? Thanks for your advice.
