### Calculating Your Monthly Income for a Sonoma County Mortgage

If you’re a first-time homebuyer in Sonoma County, knowing how to calculate your monthly income and determine your purchasing power is essential. With today’s mortgage rates around 6.5%, having a clear understanding of what you can afford is crucial. This guide will help you with the necessary calculations, formulas, and advice for your home purchase.

#### Understanding Your Monthly Income

Your monthly income is the starting point for your mortgage qualification process. Here’s how to calculate it:

1. Gross Monthly Income: This is your total income before taxes and other deductions. It includes your salary, bonuses, commissions, and any other regular income.

For example, if your annual salary is $72,000, your gross monthly income would be: Gross Monthly Income=Annual Salary12=72,00012=$6,000\text{Gross Monthly Income} = \frac{\text{Annual Salary}}{12} = \frac{72,000}{12} = \$6,000 #### Mortgage Qualification Basics Lenders use these criteria to determine how much you can qualify for: 1. Debt-to-Income Ratio (DTI): Lenders prefer a DTI ratio of 50% or less. This means your total monthly debt payments, including your mortgage, should not exceed 50% of your gross monthly income. 2. Purchasing Power Formula: Generally, lenders will offer a mortgage amount of about 5.25 times your annual income. Using the earlier example of a$72,000 annual income:

Purchasing Power=72,000×5.25=$378,000\text{Purchasing Power} = 72,000 \times 5.25 = \$378,000

#### Calculating Your Monthly Mortgage Payment

To determine your monthly mortgage payment, consider the loan amount, interest rate, and loan term.

For a $378,000 mortgage at 6.5% interest over 30 years, your monthly payment would be around$2,388.

#### Considering Additional Costs

When calculating your budget, include other housing-related expenses such as:

• Property Taxes: Typically 1-1.5% of the home’s value annually.
• Homeowners Insurance: Approximately $1,000 annually. • Private Mortgage Insurance (PMI): If your down payment is less than 20%, PMI will be required. For example, on a$378,000 home in Sonoma County, if the property taxes are 1.2% and homeowners insurance is $1,000 annually: • Monthly Property Taxes:$378
• Monthly Homeowners Insurance: $83 Total monthly costs would be: Total Monthly Payment=2,388+378+83=$2,849\text{Total Monthly Payment} = 2,388 + 378 + 83 = \$2,849 #### Qualifying Scenarios Here are a few scenarios to show how different factors influence your qualification: 1. Scenario 1: High Credit Score and 20% Down Payment • Estimated Annual Income:$72,000
• Estimated Credit Score: 750
• Estimated Down Payment: 20%
• Estimated Monthly Expenses: $1,000 With these numbers, you could afford a home with a total purchase price of$453,600.

1. Scenario 2: Average Credit Score and 10% Down Payment
• Estimated Annual Income: $72,000 • Estimated Credit Score: 680 • Estimated Down Payment: 10% • Estimated Monthly Expenses:$1,500

With these numbers, you could afford a home with a total purchase price of \$415,800.

#### Using a Mortgage Calculator

To simplify these calculations, use an online mortgage calculator. Input your income, interest rate, loan term, and other variables to see what you can afford. Here’s a step-by-step guide:

1. Enter your gross monthly income.
2. Input your estimated interest rate (6.5% in this example).
3. Set the loan term (30 years).
4. Add your estimated property taxes and insurance.
5. Include your down payment amount.

The calculator will provide your estimated monthly mortgage payment and overall affordability.
