HOA was not disclosed to me

[Jonathan C.]

I am purchasing my a turnkey property in St. Louis, Mo. I am about 2 weeks from closing and just got a trustee letter from a HOA stating that I will have to start paying monthly payments soon. My problem is that I was never told at any time during the sale that this house was part of an HOA, so the fees are news to me.

1) Are there any laws stating that a seller (turnkey company) must disclose that a house is part of the HOA?

2) I contacted the property management company asking to see their bylaws for this community.  Is there anything else that I should do?

Thanks for any help that anyone can provide.
