Who is liable if lot is not Buildable?

[Sophia Berry]

Hello all,

I am getting ready to purchase 3 lots in a subdivision cul de sac. The subdivision was built in I believe 2006 however, I am a little nervous as to why the  builder did not build on those lots.  There were two houses just built in 2013 directly across the street so I am thinking maybe the builder ran out of money and just left them.  My question is, I am getting ready to pay for a surveyor to let me know if the lots are buildable.  Would the surveyor be liable if it turns out they are not.

Any advice would be helpful.

Thanks.
