My question involves real estate located in the State of: New York

I have been jumping through hoops for over 6 months trying to purchase a church property that has been on the market for years and vacant. I was unable to find anyone willing to extend a mortgage out on a church I was goign to convert to my family's vacation home. In the end we found it best for my father to pull his 401k to pay off the church in full as no one would lend out on a church. Inspection came back clear for us. But then the state of NY sent out an inspector who appraised the church for $50,000 over the sale price. The sellers are happy with the original lower sale price, but now the NY State Attorney General has stopped the sale and advised we can not purchase the church for the lower amount, and in order to purchase the church we must pay an additional $50,000. First why would the Attorney Genral have any interest in this purchase? Why can he stop and private sale/purchase and require more money for a sale when the owner is happy and has agreed to the original offer in contract? I have never even ehard of anything like this even possible, which of course makes me question the legality of all this. Thank you to anyone who can offer some insight!!! After over 6 months of jumping through hoops to buy this property I was supposed to be closing on the home in a week, and now who knows.
