Home Buying Budget: Know Your Real Numbers Before You Shop

Your home buying budget is the single most powerful tool you have as a buyer – and it’s more than just a pre-approval letter. Before you start shopping for a new home, you need to know your real numbers.

CBH Homes Sales Coach Nick breaks down everything that impacts your buying power, from debt-to-income ratio to what’s actually inside your monthly mortgage payment, so you can shop with confidence.

What Impacts Your Home Buying Budget?

Two big factors: your income and your debt-to-income (DTI) ratio. Lenders use these numbers to calculate your pre-approval amount. Your DTI compares your monthly debt payments to your monthly income – and the lower it is, the more buying power you typically have. The Consumer Financial Protection Bureau has a great DTI explainer if you want to go deeper.

Your pre-approval amount and your comfort budget aren’t always the same thing. Just because you can borrow a number doesn’t mean it’s the right number for your life. Your home buying budget should be the payment you’re genuinely comfortable with every month.

What’s Inside Your Monthly Payment? PITI, Explained

Your monthly mortgage payment is made up of four parts, known as PITI:

• Principal – the loan amount you’re paying down
• Interest – the cost of borrowing
• Taxes – property taxes based on your home’s value
• Insurance – homeowner’s insurance to protect your investment

Always ask your lender for your all-in monthly payment – not just principal and interest. And shop around for homeowner’s insurance to make sure you’re getting the best rate. Investopedia has a solid PITI breakdown if you want to nerd out on the details.

Don’t Forget HOA Dues in Your Home Buying Budget

CBH communities include HOA dues, and they belong in your math. Nick covers what to expect and when they’re typically due, so there are no surprises. You can find community-specific details on our HOA information page.

Steps to Start Shopping

1. Talk to a lender and get your real numbers
2. Set your comfort budget – the all-in monthly payment that fits your life
3. Factor in taxes, insurance, and HOA dues so nothing sneaks up on you
4. Start shopping with confidence at cbhhomes.com

Frequently Asked Questions

How do I determine my home buying budget? Start with a lender. They’ll review your income and DTI to calculate your pre-approval, then work backward to the all-in monthly payment you’re comfortable with.

Is my pre-approval the same as my budget? Not necessarily. Your pre-approval is your ceiling. Your comfort budget – the monthly payment that fits your actual life – is your real number.

What is PITI? Principal, Interest, Taxes, and Insurance – the four parts of your monthly mortgage payment. Always ask for the all-in number.
