I purchased an investment property out of state. I signed an agreement with a wholesaler who in turn hired a real estate agent (which I could have done myself but the wholesaler said he had a cash buyer, I digress). Any how the agent ended up sending me a seller's contract to sign so he could list the property and do his business. I signed it since I had gone that far already. My question is if I change the property to an LLC out of my name are those contracts still valid? Thanks in advance and I appreciate any clarity offered on this situation.

Yes, your liability remains the same.
