(Gas leak and plumbing) What are some things you have ran into when dealing with this?

We assumed we could patch/repair the leaks, but after a few quotes it made no sense to Band-Aid it. 

There were a LOT of issues with it (some rotting floor damage from a badly insulated crawlspace, pipe leaks, etc), so I was able to negotiate for $7,500 under my original offer plus $10k in sellers credits (covered closing costs and 3 mo's mortgage + taxes) How did you finance this deal?

@Jay Sheth I’ve had two 110+ year old mansions and I’ve had to deal with asbestos, 40 year old furnaces, old plumbing, knob and tube wiring, electrical that was on fuses which was up to code but would blow periodically and then if you didn’t have spare fuses it was a problem, roofs that got ice dams every year because the houses were only meant to be summer homes, under ground oil tanks, leaking gas lines.

I purchased a 2 unit house with a neglected Soffit & Fascia & gutters that are destroying the downstairs unit and basement (water leak).

Mold from a roof leak in the back laundry room caused most conv. financing denials.While viewing the home our agent called the bank in TX & we had a verbal for $21,000 CASH.We did nothing to it but our new buyer restored it beautifully.2.

It was leaking freon but I topped it off a couple of times over the three years I lived there.

It can cause issues with who maintains it and also with insurance claims if a leak or damage occurs.

@Thomas Moran as long as there is no leaking into the basement , the inside floors are sound, go for it, Simply tuck point the areaGood Luck
