Gand, another question to ask yourself is why would they even bother with this geological survey and have an outstanding bill due of $41,000 plus the downpayment IF THEY DIDNT HAVE ANY SITE (KRONG) WORTH VALUE. Think on both ends before presenting only 1/2 of the equation.
It is my understanding that these reports were requested buy an interested buyer. The cost will be pasted on to that buyer if they do indeed buy. So why spend cash on hand when you can finance it and pass the payment book onto the new owner.
