Tyvek isn't waterproof, BTW. Properly placed tarps would be needed to waterproof.
Disclosure laws vary from state to state. I am licensed to peddle real estate in two states, and the laws there are different enough to make requirement of certain disclosures confusing to say the least. One state dictates that certain "psychological" impacts (death, suicide, etc.) which happen in a property cannot be disclosed to a potential purchaser without the express permission of the seller. The other state says any such information must not be disclosed, period.
However, if a real estate agent is acting as a buyer's agent, a duty exists to try to find out if a property is "impacted" in such a fashion. I could (should) ask a listing agent if a suicide took place in a house, but that agent can legally respond that she has no information in that regard released by the seller.
I don't know how serious you were when you mentioned informing potential buyers about certain "aspects" of the rowhouse, but I'd advise you remain mute. Even if you conveyed a truthful utterance which resulted in a buyer not purchasing the property, the cost of defending yourself against the almost certain civil action against you would be considerable. Truth might be a good defense, but it don't pay the legal bills.
As to the framing being exposed to the elements: in my experience, every structure is so exposed. One can only hope any moisture present is eliminated before the house is enclosed and finished.
