Mortgage Payment Information
Down Payment:  $10,900.00 

Amount Financed:  $98,100.00 
Monthly Payment:  $430.72 (Principal & Interest ONLY) 
Since you put less than 20% down, you will pay Private Mortgage Insurance. PMI tends to be about $55 per month for every $100,000 financed (until you have paid off 20% of your loan). This adds $53.96 to your monthly payment. 

Your property tax rate is $2,100.00 per $1000. Your home's assessed value is $92,650.00. This means that your yearly property taxes will be $2,100.00, or $175.00 per month.

Calculations
To figure out the monthly payment, we need to know (1) how much you're financing; (2) your monthly interest rate; and (3) how many months you're financing for.
Financials are typically quoted in yearly or annual numbers  a 30year mortgage or a 6% annual interest. However, you pay your mortgage every month. A lot of the calculations involve translating those yearly numbers to their monthly equivalents.
1. Financing Price
First, we need to figure how much you're financing.
We can do this based on the sale price of the home ($109,000.00) and the percent that you put down (10%).
Start by calculating the down payment. Divide the percentage down by 100, then multiply by the sale price of the home.
(10% / 100) x $109,000.00 = $10,900.00, your down payment
Now we can calculate how much you're financing  how much you need to borrow. That's just the sale price minus your down payment.
$109,000.00  $10,900.00 = $98,100.00, your financing price
2. Monthly Interest Rate
That 3.32% interest rate percentage you secured is an annual percent.
We'll need to convert that from a percentage to a decimal rate, and from an annual representation to a monthly one.
First, let's convert it to a decimal, by dividing the percent by 100.
3.32% / 100 = 0.0332, the annual interest rate
Now convert the annual rate to a monthly rate by dividing by 12 (for 12 months in a year).
0.0332 / 12 = 0.0027666666666667, your monthly interest rate
3. Month Term
Now for an easy calculation  the month term. That's just the number of months you'll be paying off your loan.
You have a 30 year mortgage x 12 months = 360 months, your month term.
Final: Your Monthly Mortgage Payment
Using the three numbers above, we can now calculate your monthly payment.
(financing price) x (monthly interest rate / (1  ((1+monthly interest rate)^{(monthly term)})))
$98,100.00 x (0.0028 / (1  ((1 + 0.0028)^{(360)}))) = $430.72, your monthly payment*
