Residential (or Property) Taxes are a little harder to figure out... the average residential tax rate seems to be around $14 per year for every $1,000 of your property's assessed value. Let's say that your property's assessed value is 85% of what you actually paid for it - $9,137,500.00. This would mean that your yearly residential taxes will be around $127,925.00.
This could add $10,660.42 to your monthly payment.
Since you are putting LESS than 20% down, you will need to pay PMI (Private Mortgage Insurance), which tends to be about $55 per month for every $100,000 financed (until you have paid off 20% of your loan).
This could add $5,321.25 to your monthly payment.
