The buyer already had a $45 million mortgage on the property, so while this transaction cost them $6.5 million, they are not valuing the building at $6.5 million.
I guess that depends on if it was an open auction and if the bank placed the top bid.
Sales dont have to be at arms length. It is just that if they aren't, it opens price and sale process to scrutiny for self dealing. it doesnt mean that self dealing occurred.
If you fund the purchase with debt and assume a interest rate of 5%, you are talking 325k/year for the building.
I wonder what the upkeep costs are? I wonder what the depreciation schedule looks like for office buildings.
