It has central heat and air, 1200 sq ft, and a restroom.

The other realtor said all the plumbing, wiring and heat and air are all in working condition.

You were shilling for it whether or not you want to hear it.In case you weren't familiar with shills, here is a definition:A shill is an associate of a person selling goods or services who pretends no association to the seller and assumes the air of an enthusiastic customer.

I wanted to disappear into thin air right then.

This way they can keep up and your heating and air conditioning units will survive.

Money doesn't come out of thin air so when you take money from 1 property to put into another, you're robbing Peter to pay Paul.

It gets worse:Someone shot out bedroom window with BB gun and stole the copper out of the air conditioner unit.

Central heat and air and all the duct.

If the water smell rotten, it has sulfter and I believe is only curable with a carbon filter system of some sort.If it is just brownish in color, like suggested previously use an in line water filter BEFORE the air pressure bladder.

My Realtor suggested that I may just want to "change the air filter" each month and do them myself.
