Update:
Day 7 of the 10 DD:
My home inspector did a great job on inspecting the house on day 6. He found several minor issues we expected but the MAJOR issue he found was that the 8 car garage addition ( 42ft x 42ft ) was build directly over the septic tank and drain field. Now we know why the listing agent and seller kept blocking our due diligence inspections. We double check the "sellers disclosure" and the seller listed the property was on sewer. The listing agent has 25 years experience in the community and he either did or should have known about this defect.
Day 8 of the 10 DD:
At 10am my agent and a local septic company did an inspection and confirmed the tank was under the garage.
We called the county building office: NO building permits ever filed for this property. We contacted the county health department and the water department: NO record of where the tank and drain field is located in their files but they both confirmed there is NO SEWER in the area. Building inspector dropped everything he was doing and we immediately meet to the property. Seller refused to let me in and also refused to let the building inspector look at the garage. The county health inspector plans to come out next week. We asked seller for an extension, they refused.
Day 9 of the 10 DD:
Spoke with 2 lawyers referred by closing attorney's in the area. Met with another attorney and he stated that since we now know about the problem we can not file a law suite if we buy the house. Also will loose our EM if we cancel after the DD.
1. We don't know if the tank can be moved without tearing down the garage.
2. We don't know if there is a 2nd drain field area available
3. We don't know if the garage is safe or was built to code
4. We don't know if the ground under the garage is stable or will remain stable
Around 5pm that day, the seller sent a counter offer to sell us the house "as is" for the same price.
Day 10 of the 10 DD:
We canceled.
