thank you the next one in Charleston I will post is our first venture into the historic district were the rules and regs are quite stiff and the homes are museum grade.. you know horse drawn carriages gas light lamps very cool..

Most tenants around here do pay for their own electric and gas.   

It looks old, but isn't leaking.

In regard to utilities, It is very common to have the tenants pay for Electric and Gas while the landlord pay for water Trash etc. 

Not in a accusatory manner, but I'll ask some prodding questions re: if there are any potential leaks or the like in the home that they are aware of.

After that you start seeing low pressure and more and more leaks.

If done correctly you'll never have to worry about it, just make sure all the penetrations are flashed appropriately so you don't have leaks seeping in.

I purchased a home about 6 months ago, and I split the gas lines and added a second boiler.

Does the site have access to electrical power, natural gas, town water or sewer?

I am in Due Diligence on a deal, when I find out that there was a leak in this 1400 sq ft. town house less than a year ago.
