Bought half a double lot, but the house is on the property line

[Vida Novak]

Working on a house flip, but have a bit of a concern.  A wholesaler sold me the house-half of a double lot.  Typical strategy, they hold and sell the empty lot separately, I didn't have a problem with it, as I got a good deal.  However, after doing some more research, it appears that the house I am rehabbing is much too close or pretty much sitting on the property line between the two parcels.

First, get out of the way that I fell just a little short on the research end, because I knew about this before and I should have made the offer for both lots together, or at least figured out the ramifications of this situation in advance.  I am not completely inexperienced and I certainly knew better.  Let fly the chastising, but I'm hoping for more constructive input.

I'm wondering if anyone has any experience with this and how I am supposed to deal with this situation.  Obviously the original owner of the lots was not concerned about the property lines, so they put the house where they wanted.  I feel like there must be some laws or zoning regulations that would prevent the seller from doing this.

Who is really responsible here and what is the process to clear up this situation?  I don't know if I believe the seller should be required to give me the other lot for nothing, but then again, I can't be required to "move the house", right?  The seller tried to sell the parcels separately, thereby creating the violation, so shouldn't they be responsible?

What excitement!

To be clear, you created this violation, along with help from the seller.  Forget about the seller being responsible.  Are you really not going to get it surveyed, and try to correct it, and just wait for the buyer's survey, when they have to walk?
