Funny fact:-the Canadian immigration website is down because the server crashed.

If I do need to contact them for late rent, I have a professional process server post the three day, and I also text that it is important that I hear from them on a very important matter!

Then she says that she used the night drop for the deposit and they must have lost it in the slot.  

Thank you @Jeff S.  lots

Sometimes you get caught in a storm without an umbrella when it was a 10% chance of rain and sometimes you hit a jackpot on the slots.

I do as Bryan A. said - use same brand and just change outside parts that have key slots; tenants comprehend that the old key no longer has any chance of opening locks that are physically changed this way.I have seen the landlordlocks.com product demo'd in person, and that is the way to go once you get lots of units - mainly because you still can have a master key that accesses any lock.

It's all done up as a secure website running on my own server - so I can manage my properties from anywhere in the world ( or mostly, everywhere in my house, cuz I don't go anywhere much :).

I have been a server and bartender in fine dining restaurants for the past few years.

They should have an online map server that allows you to search by address, owner name, etc.

I'm considering RV slots ( for Snowbirds, vacationers, and refinery/turnaround workers), MH pads, cabins, etc.
