What we always say is " We have never had a theft, break-in, or vandalism in any facility we have ever worked in the 14 years we have been doing this"

" That doesn't mean it can't happen or wont happen" , "But that is because we do things different at our facility"
" We do criminal background checks on every tenant,

but for your peace of mind if you don't have homeowners or renters insurance we do offer insurance for your storage needs, and you can pay that right along with your monthly rental fee, and we hand them a brochure ...
"We even have door bells installed on the outside of the office and even if the office is closed and you have a problem with the gate or see something that needs our immediate attention , we live here on the property and we will come right out and help you...We also ahve phone numbers posted by the key pad and by our office door and if you cant get us you can call our corp office any time , and they can help you too.
And you can believe if it is a criminal they come up with the excuse I left my wallet at home , or I have to go to the bank, and they never come back ..

So we weed out the criminals before they get a foot hold in our facility, and if they ask about our security , then they are either truly concerned or checking us out for later ,, so we show them the unit we are going to put them in and say , since you are so concerned about security then we are going to put you in one of our most secure units , right here under this camera, and right here where we can see your unit at night.. They never say I don't want the most secure unit , in fact if they do have any intentions they also come up with an excuse not to rent ..
We also tell tell them about our frequent lock checks and what the seals on the locks are for...etc ...
Also that when they come into the facility we may drive by in our cart once and maybe 2 times to make sure everything is Ok ... this also weeds out any potential criminals. Just my 2 cents on the subject ..
