Even if you don't, you will be better able to maintain the temps you want on each floor, that way.

(I have used craigslist shared/temp postings, craigslist wanted, and church/community boards in the past to find affordable living.)You can use the saved time to work longer, potentially, and make $50-100 more every day.

Keeps the heat at a certain temp? 

I tend to believe in the climate scientists, who say that as the world's temp. gains 1 degree celcius, which say isn't too far off, in years; then they say that most of California will turn into a desert, without adequate water.

Odds are, they are also looking for you - you just need to connect.There is also the possibility of doing a corporate rental - where a company, like a temp agency for traveling nurses, wants to just pay you a regular rent that they guarantee you, and their employees come and go. 

They may be thinking you want to bury your pipes under the property when you are only requesting temp access to perform the work. 

It's a rarity for the temp to get to 117, though the all time record was set on July 20,1988 at 118, I remember it well, it's the day my son was born.

With the hot water heaters in each unit, they could control the temp of the water, too.Each unit also had it's own gas wall heater. 

Somewhere from $1,500 to $2,500 seems a typical amount.I ran across one firm out of Tempe, AZ that offers a "free" tax lien foreclosure.

Best to check with the utility company or count the electric meters - if there are more meters than there are doors you probably have to pay something to light/heat stairs, halls etc. each month, especially in a climate with below freezing temps.
