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 - $9,562,500.00. This would mean that your yearly residential taxes will be around $133,875.00.
This could add $11,156.25 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 $5,568.75 to your monthly payment.
