Half-way through construction on my new home, I discovered a large drain in the backyard that i believe wasn't there when I entered contract. Builder says it was, I say it wasn't and I have photos that support my case. Regardless, there is clearly a drainage easement on the lot that I was not made aware of prior to contract signing. I did not review a plat but I did inspect the lot. Should I have been told of the easement by the builder/his listing agent before entering into contract? It seems to me that not learning of an easement on a lot until 'closing' is too late. Thank you.
