He convinced her somehow and I gave him half in order for him to have gas to take her to her new place.

One example of this was when I went to have the gas company come out to turn on the gas to the house, the guy wouldn't turn it on because the meter was under the deck.  

New kitchen, dealing with tenants schedule, changing the new stove from gas to propane, ect.

When my power was out, I ran my generator all day and used about $10 worth of gas to power less things.

4) Does anyone here have an issue with landlord-paid heat that uses natural gas to boil water?

It has city water, sewer and gas to the street.

Also, how much should i expect for about a 75-100 gallon gas to cost me?

But even at $200-225/mo in ferry auto pass (or $60-70/mo for walk on passenger tickets) - $200-$300/ mo is what people are paying for parking and/or gas to commute to work in Seattle.

Adding on-demand heaters at point of use is often easier and less expensive than recirculation.Those same homes that "are not plumbed for recirculation" generally are also not wired for 240V in the bathroom (where the shower is), or enough amperage at 120V to sustain an electric on-demand tankless heater with sufficient capacity (after calculating winter drop temperature vs flow rating), much less plumbed for natural gas to support a non-electric model (which is the only type I'd recommend).

Gas to drive to the property and lawn equipment to maintain the property along with other home office expenses.
