Higher security deposit for more tenants

[Angelo R.]

Standard practice seems to be a fixed deposit amount per unit, regardless of the number of tenants. While there are other factors and exceptions, more people generally can cause more damage than fewer people. 

I always see landlords asking for additional “pet deposits,” operating under the notion that pets are potentially more destructive than people  

Applying that logic to a $1000/month rental unit that can accommodate 4 people, would it make sense to set the security deposit to $1000 for 1-2 people, and $2000 for 3-4 people?
