First off, I've found tons of good information here. I'm not a home inspector but do plenty of work on my house and understand the basics of most systems. I'm also fairly obsessed with all the home improvement shows out there on TV so I may have enough knowledge to be dangerous as they say. Anyhow, my wife and I are currently wading through the short sale process on a house that's been unoccupied for over 2 years. The location is outside of Philadelphia so the winters can get cold. Someone at sometime "winterized" the house. I use quotes because some effort was spent, but apparently not enough. The toilets all have some type of antifreeze in them and I believe most of the water lines were drained (the main water connection is completely disconnected for some reason). However, the house has a boiler and uses hot water baseboard heaters for warmth. From my quick inspection I found 3 burst pipe sections in the base board heaters so these were obviously not drained properly. There was minimal leakage once the pipes thawed out again but nevertheless this represents some issues that will have to be addressed. What else should we look for considering the house has now weathered two winters without maintenance? One other issue I'm a bit concerned about is that there was an additional two rooms added at some point which are heated by radiant in floor heating. I have no idea what the condition of these pipes are or how to check. I suppose a plumber would be able to pressure test them somehow to make sure they aren't breached?? I'm trying to gauge how much money we'll need to spend upon moving in so any tips would be helpful as this is our dream house at a potentially good price. Thanks!
