ok gentlemen. met with my SE at lunch today.
basically, the garage is an addition and the slab is sinking at the back and pulling the whole thing off the house. the back stairs that were sinking were also an after-the-fact addition, and are not supported by the house's foundation so they are basically just sitting on dirt.
These issues can be solved by jacking up the garage slab with piers and mudjacking the back steps. (according to my guy).
All for the grand total of about $25,000.
HOWEVER,
we noticed a few other things that i hadn't picked up beforehand, such as some definite bowing inward of the foundation walls on the OTHER side of the house. Due to the age of the house ~75 years, the foundation material is basically stone and crappy mortar. This means that if you place piers, you can only stabilize, not actually lift the foundation, lest you want it to crumble. This means it would require piers ALL THE WAY around the house, with a 'connecting strap' to avoid sinking in between piers. The cost for this? An ADDITIONAL $30,000
Of course this doesn't include patching the brick, walls, fixing cracks, leveling floors, or of course, any cosmetic fixes. We could probably be talking another 50-70k for all of that.
While i was there i noticed the house across the street did sell this week, for $149,000 more than this house was listed at. Doing all the math with the required repairs, it adds up to something like ~105-120k, which would still put us in the range of 30k ahead is the home was purchased at list price (and NO SURPRISES Came up during construction! yeah right)
At this point, after having had ~48 hours to consider it, i'm leaning towards NOT making an offer on this house, but haven't made a final decision yet. Need to review with my wife tonight, but since she is in the medical field, she generally leaves this kind of stuff up to me. While it looks like it could be a chance to get a great deal, it could also lead to a big headache and i don't think we want to deal with a project of this size on our first home.
I have pics of the house and some of the issues i will try to upload shortly!!!
thanks for all your help, and at the very least i found this a useful exercise in analyzing homes as i am still very interested in this neighborhood!
