One of the boring things about actually being a housholder (rather than a renter) is that you've got to do the maintenance on the place. Paint it, make sure the roof and windows are sound and so on. These things aren't cheap alas, either.
One thing that many forget, especially in areas like New Jersey, where the weather varies a lot between summer and winter, is mold testing. It's essential to do as if you start getting mold in the basement or, horrors, in the roof area, it can quickly eat away at the structural integrity of the house.
As well as being just gross, you know. So, take this as a hint to click through above there and get the guys around to test for mold.
