If you were to tell the movers you'll pay them later when you get the approval from your bank to make payment, do you think the movers will take that lying down?  How about the property owner who's building  he's leasing.  I really doubt it if they'll say "its ok, you can pay your rent later when you get approval" and allow it to happen.  
As for  him taking the offer of $2.7m for his property, let me ask you the same.  If your house is appraised at $1 million dollars and the city offers you $500,000 for it because their appraiser valued it as such, would you take it?  If the city says if you don't take the offer, they'll just take it by condemnation, wouldn't you fight it also?  Hoernig did and won a larger settlement, now the city and HART need to pay up, especially if it was ordered by the court to make payment by a certain time.
