So, there could be more substantial damage than you can see right now (does it freeze there during the winter?).

Replace all plumbing with pex, when it freezes it flexs and won't burst like pvc or copper.

It's a huge liability in cold climates as the tenants will never shut off the water supply in the winter causing freezing and potential water damage.

Yesterday (Sunday), I received a call from my tenant stating that I need to give her grocery money.I had someone go out and verify the freezer wasn't freezing, and ordered a brand new refrigerator from Lowes which was delivered today (Monday). 

What landlord has a swimming pool and allows it to stay full during a freeze? 

Here in CT, as in Ohio, the "hold" scenario kinda stinks when you're faced with freezing temps.

I am guessing they give an exemption for over 65 in Dallas instead of freezing taxes like they do around me. 

search "spigot lock" and you will find what you need.btw, i would just eliminate the spigots all together. they can freeze in the winter anyway.

@Rafael Norat You can freeze your credit for free with all 3 reporting agencies where no one can open anything in your name.

In the winter, in colder climates, make sure your unit is kept at a temperature no less than 50 degrees, otherwise there is the potential for freezing pipes and structural damage.Twice we have found candle burn marks under kitchen cabinets and wax drippings in carpets after tenants had their electricity cut.
