What Is DTI and How Does It Affect My Home Buying Power?
By Stephen Palermo with Gold Standard Mortgage, your trusted Visalia loan officer

When buying a home, one of the most important numbers I look at is your Debt-to-Income (DTI) ratio. As your trusted Visalia loan officer, I’ve helped many Central Valley clients understand and improve their DTI to get approved for their dream homes. In this guide, I’ll break it all down for you.

🔎 What Is Debt-to-Income Ratio?

Your DTI ratio compares your monthly debt payments to your gross monthly income. I use it to decide if you can handle a new mortgage. A lower Debt-to-Income Ratio means more borrowing power and better interest rates.

Formula:
Debt-to-Income Ratio = Total Monthly Debt Payments ÷ Gross Monthly Income

💡 Why Does Debt-to-Income Matter? What Is DTI?

I want to know that you can afford your new home and your current debts. Your DTI helps show that.

  • Low DTI = Less Risk = More likely to get approved

  • High DTI = More Risk = Less likely to get approved or might receive worse loan terms

📋 What Counts Toward Your Debt-to-Income?

Included in Debt-to-Income Ratio:

  • Mortgage or rent

  • Property taxes and homeowners insurance

  • Auto loans

  • Student loans

  • Credit card minimum payments

  • Personal loans

  • Alimony or child support

  • Co-signed loans

Excluded from Debt-to-Income Ratio:

  • Utilities

  • Cell phone and internet

  • Car and health insurance

  • Groceries

  • Entertainment and gas

🧮 How to Calculate Your Debt-to-Income

Let’s break this down step-by-step.

Step 1: List All Monthly Debt Payments

Include every monthly debt bill. This means mortgage, rent, car loans, student loans, credit cards (minimum payment only), and any court-ordered payments.

Step 2: Find Your Gross Monthly Income

Use your income before taxes. This includes:

  • Job salary

  • Bonuses or commission

  • Alimony or support income

  • Side gigs

Step 3: Divide Debt by Income

For example:

  • Monthly debt payments = $2,000

  • Gross income = $6,000

  • DTI = $2,000 ÷ $6,000 = 33%

📊 Front-End vs. Back-End Debt-to-Income Ratio

Front-End DTI:
Includes only housing expenses (mortgage, taxes, insurance, HOA).

Back-End DTI:
Includes all debt payments (housing + loans + credit cards).

Lenders usually check both.

✅ What’s a Good DTI?

I look for:

  • Front-end DTI: 28% or less

  • Back-end DTI: 36% or less

FHA loans may allow up to 50% Debt-to-Income Ratio in some cases.

🏠 How Does Debt-to-IncomeAffect My Home Buying Power?

Your DTI directly impacts how much home you can afford.

  • Lower DTI = Larger Loan Amount

  • Higher DTI = Smaller Loan or Denial

Let’s say you make $6,000/month:

  • With a 36% DTI limit, your total debt can’t exceed $2,160/month.

  • If current debts are $1,000/month, that leaves room for a $1,160 mortgage payment.

If your Debt-to-Income Ratio is too high, I may:

  • Decline your application

  • Offer a higher interest rate

  • Require a larger down payment

  • Suggest a less expensive home

🔧 How to Lower Your Debt-to-Income Ratio

You have three options:

  1. Increase your income

  2. Reduce your debt

  3. Buy a less expensive home

🤑 Ways to Increase Income

  • Ask for a raise

  • Take on overtime

  • Get a side hustle

  • Start a small part-time business

💳 Ways to Reduce Debt

  • Focus on high-interest credit cards

  • Use the snowball or avalanche method

  • Refinance student loans

  • Use a balance transfer card (with caution)

  • Cut back on subscriptions and dining out

  • Pause savings to prioritize debt (short-term only)

Even small changes can lower your Debt-to-Income Ratio fast.

🛠 Use Debt-to-Income Ratio to Strengthen Your Mortgage Application

Before you apply, knowing your  gives you power. You can:

  • Plan ahead

  • Avoid surprises

  • Choose the right mortgage type

  • Work with someone like me to get prequalified
