Pooling resources for private security: Pros and Cons?

[Nathan Guyette]

Currently I'm thinking of pooling resources of several landlords in my area to try and patrol properties.
I'm looking for pros and cons. Here are my thoughts so far:

Pros:
Lower crime rate, higher confidence of renters in the future.

Cons:
Slightly higher rent, depending on how many landlords are interested in participating

Of course there's really no way to know ahead of time, but I'm hoping that the small investment in private security will be enough to raise the confidence of renters in the future. Not sure what the numbers come out to be. Looking for comments, concerns or criticisms. Thanks!
