By forgoing the rent increase, I'm probably costing myself about $120 ($10/month), but I think I make up for it by getting her off money orders and onto electronic transfers.

I've started going to electronic keypad locks so I can change the access code.

Do not leave electronics/lights on when not needed.ii.

Quote from @Joshua Hughes: I would recommend electronic locks.

You also have electronics which are more sensitive to electrical issues.  

For my LTRs, I embeded a Google form into a Weebly website and created my own electronic application.

Therefore, you will not have to secure any cash, worry about more expensive equipment being damaged or stolen and all money is transferred electronically to your account.

They can absolutely charge you for the time it takes them gather the info for you and to print it out or put it into electronic format.

If we were able, I would use one of those electronic lockboxes instead - the type where the guest punches in a code and then the door unlocks, rather than having a physical key - but it wasn't in our budget.Another key hire for renting from a distance hire would be a local handyman to handle any emergencies that come up while guests are staying there.

I just had a mouse problem too and went and bought 3 Victor Pro Electronic mouse traps on eBay and I caught a bunch of mice and so far have not seen or heard anymore at the property.
