How to Assess Affordability When Buying Your First Home

1. Calculate your debt-to-income ratio (DTI)

The first step in assessing affordability is understanding how your income compares to your debts. Your debt-to-income ratio (DTI) measures the portion of your gross monthly income that goes toward paying existing obligations like credit cards, car loans, and student loans, plus your projected housing payment.

There are two key types of DTI to know:

Front-end ratio: The percentage of your income that goes toward housing costs, including mortgage principal, interest, property taxes, and homeowners’ insurance.
Back-end ratio: The percentage that includes all debts combined with housing costs, plus credit card, car, and other loan payments.

For example, if you earn $6,000 a month and your total monthly debt payments (including your estimated mortgage) are $2,400, your total DTI is 40%.

Lenders use these ratios to determine how comfortably you can manage new mortgage payments. Keeping your DTI lower not only improves your chances of loan approval but also gives you more room in your budget for savings or unexpected costs.

2. Estimate your monthly mortgage costs

Once you understand your DTI, the next step is to estimate your full monthly mortgage payment. The standard calculation is known as PITI, which stands for principal, interest, taxes, and insurance:

Principal: The amount you borrow to purchase your home. Each payment gradually reduces this balance.
Interest: The cost of borrowing money from your lender. Your interest rate and loan term determine how much you’ll pay over time.
Taxes: Property taxes are based on your home’s assessed value and local tax rates, and they’re typically included in your monthly mortgage payment.
Insurance: This includes homeowners’ insurance, which protects against damage or loss.

If you’re using an FHA loan, you’ll also need to factor in mortgage insurance premiums (MIP) and the Upfront Mortgage Insurance Premium (UFMIP). These are required for all FHA borrowers and are designed to protect the lender in case of default. While the UFMIP is usually paid at closing, the MIP is added to your monthly payment and continues for the life of the loan in most cases.

To see how these costs fit into your budget and change your monthly payments, use an FHA mortgage calculator. It can help you estimate your total monthly payment, including insurance and taxes, so you can plan more accurately and avoid surprises later.

3. Account for personal spending and savings goals

Even if a lender approves you for a certain amount, it doesn’t mean that the loan will fit your lifestyle. Your personal expenses and savings goals should also shape what you can realistically afford.

Start by reviewing your monthly budget. Track recurring costs such as utilities, groceries, transportation, childcare, and healthcare. Then, factor in lifestyle spending like dining out, streaming services, or travel. These day-to-day choices impact how much flexibility you have each month once your mortgage is added to the mix.

It’s also essential to plan for savings and emergencies. Experts typically recommend keeping three to six months’ worth of living expenses set aside in an emergency fund. This fund should cover your mortgage payment, utilities, and other essentials if an unexpected expense or job loss occurs.

4. Set a comfortable price range

After you’ve considered your DTI, estimated monthly payments, and personal budget, you can determine your ideal price range, which is the amount that fits comfortably with your financial goals and lifestyle.

There’s often a difference between what you qualify for and what you can comfortably afford. Lenders base approvals on formulas, but only you know how much financial flexibility you want to maintain.

A good rule of thumb is to keep your total housing costs under 30% of your gross monthly income. For example, if you earn $6,000 a month, aim to spend no more than $1,800 on housing-related expenses.

Before making an offer, revisit your numbers. Consider whether the home’s taxes, insurance, and maintenance needs might stretch your budget. Buying below your maximum approval amount can give you room to breathe and help ensure long-term financial stability.

Buy confidently with preparation

Assessing affordability when buying your first home is personal to you and what makes sense for your future. By calculating your DTI, estimating your full housing costs, accounting for your personal spending, and setting a price range that aligns with your goals, you’ll have a clearer picture of what you can truly afford.

Planning helps prevent financial strain and sets you up for a stable future in the long term. When you understand your budget from every angle, you can pursue homeownership with confidence, knowing your new home fits both your lifestyle and your long-term financial plans.
