I think this is a terrible idea straight up. I like the idea of maybe stashes having an added purpose to double as a drop box but this, no.
The idea of bringing illegal RP in the scale of crew deals into properties where almost every single faction has clear rules defining no criminal activity is to take place in them is silly.
"This is an added risk that actually sets properties as valid targets, that *can* finally be seized for conduct, as currently its very rare that a property is seized."
^ There is a reason property seizure is rare, it's because HC puts rules in place to not do any stupid illegal shit inside their properties! It's not a bad thing that properties you paid a lot for aren't getting snatched by cops left and right.
"Your properties at risk, but your men are safe. You can rebuild, maybe get the property back. Most factions have 2 properties, one they use and one they don't. The risk would be losing a property you're probably not even using." There is so many things wrong with just this sentence alone.
What makes you think people aren't getting killed for getting a property seized??
Most factions pay at least 2 million for a second property. There any many reasons why you would want a second property like a 2nd hiring location, place to meet, events, etc. Saying "Well most people don't use those so might as well risk them being seized" is just . Maybe back when factions could own more than 2 properties, but in this era, no.
I think the only people that would use this feature are newer factions who maybe don't have an apartment, which again, is not a good thing.
Why would you risk 1 entire property, rather than 1 apartment room. To save some guys? In that case, only do 1 on 1 deals.
tl;dr Not worth the risk of losing a property (potentially indefinitely). And if caught cops are swarming/seizing your "legal business" (with HC names likely tied to it), opposed to a shitty apartment room.
