That being said, is it a real estate strategy to mark that box so buyers can't withdraw offer upon discovery of lead based paint upon inspection?

After taking the time to research this, should take less than a hour of online research, politely inform the contractor of your discoveries and see how he reacts.

Little known fact is that many lenders, banks and loan servicing companies must call the note upon discovery.

Based on experience being in various tax assessment discovery failures by title companies, I have been able to exercise my title insurance on several occasions and has worked well, not instant but it worked.

After, I stepped out of my comfort zone and purchased a "junker"..The best discovery in my business model...Good luck!

I like the discovery route.

Also, this type of O&G investment is the most highly tax-advantaged asset class, even more so than real estate.Another discovery was that it's nice to have a steady stream of O&G cashflow in my portfolio to cover the inevitable hiccups with real estate (single family homes), including turnover vacancy, unexpected repairs/maintenance, etc.For me, the O&G has been a stronger cashflow asset out of the gate, with expected decline as production wanes over the long term. 

The point is, all those shadow homes have/had occupants at one time and notwithstanding several mass-grave discoveries on the horizon, all those people are still around.

the kind that bite and melt your flesh off (or so I see from Discovery Health Channel).

Landlord agrees to initiate repairs in a timely manner following discovery of the damage or can choose to defer repair until Tenant has vacated the premises.
