Those are the only two things in her house that run on gas. 

Where you might run into issues is getting permits closed out if you have a gas line out there (for an oven) or a 220v (that appears to be for an oven).

It’s old and has previously had a roof leak but has been fixed and not leaking anymore.

The only unexpected thing was I re piped the downstairs water from PVC to pex.. it had a couple leaks and I figured it'd be easier to get it done with me living there vs when it's rented.

I own a duplex and I live on the 2nd flr Recently there was a toilet leak coming from my unit.

Chances are there is a leak somewhere, usually a toilet flapper.The thing that made this a no-brainer for us was several times tenants failed to report leaky toilets, and since we had no way to PROVE it was their leaky toilet that caused the entire high usage we ended up eating the bill. 

But as you look into it you see:no separate water meters so the owner paysno separate electric meters  so the owner paysno separate gas meters so the owner payshave to pay trashhave to mow/handle snowhigher property management feesetcSo the single family might be making way more money at the same price, despite the fact that the triplex has $500 a month more rent. 

Just spent $3,400 on a gas leak at a property this month so I’m in the red for Feb. 

For example, I specialize in half a dozen or so of the above topics, but if you were heavily invested in Oil & Gas, I'd refer you somewhere else as that is not my specialty.A generalist may or may not know real estate well enough to help you out. 

They had a water leak behind the kitchen sink and took the landlord almost a month to fix.
