How Lenders Look at Your Income: 4 Things That Determine Your Mortgage Approval

When it comes to buying a home, it's not just how much you make — it's how you make it, how it's documented, and how consistent it is. This video breaks down the four key things lenders look at when evaluating your income for a mortgage: stability and consistency, debt-to-income ratio (DTI), qualifying vs. non-qualifying income, and what self-employed borrowers need to know.

How Lenders Look at Your Income

When you apply for a mortgage, lenders don't just want to know how much you make. They want to know how you make it, how consistent it's been, and how well it's documented. Here are the four key factors that determine how your income is evaluated.


1. Stability and Consistency

Lenders want to see a 2-year history of income in the same field of work. This doesn't mean you need the same employer for two years — it means a consistent career pattern.

What typically works:

  • Same job for 2+ years
  • Job change within the same industry
  • Recent graduate in a field directly related to your degree (school history can substitute for work history)
  • Promotion or raise at the same company

What raises flags:

  • Frequent industry changes with gaps
  • Unexplained employment gaps
  • Recently started income with no prior history in that field

Lenders also require verifiable income — income they can actually see on a W-2, pay stub, tax return, or official bank statement.

For hourly workers: You may need to document average hours worked over time. For part-time or variable income workers: Expect to document income over a longer period.


2. Debt-to-Income Ratio (DTI)

DTI is one of the biggest qualifying factors in any mortgage application. It's the percentage of your gross monthly income that goes toward monthly debt payments.

What's included in your DTI:

  • Car loans
  • Student loans
  • Credit card minimum payments
  • Personal loans
  • The new projected monthly mortgage payment (PITI)

How to calculate it:

| Example | Amount | |---|---| | Gross monthly income | $6,000 | | Total monthly debt payments (including new mortgage) | $2,400 | | DTI | 40% ($2,400 ÷ $6,000) |

General guidelines:

  • Most loan programs want total DTI under 43–50% (varies by loan type)
  • A lower DTI typically means better loan terms and a larger purchase amount
  • If your DTI is too high, there are often ways to reduce it — paying down specific debts or adjusting your target purchase price

3. Qualifying vs. Non-Qualifying Income

Not all income counts for mortgage qualification — even if the money is real and in your account.

Qualifying income includes:

  • Full-time W-2 wages
  • Consistent hourly wages
  • Verified part-time income
  • Bonuses or commissions consistent over 2+ years
  • Alimony or child support (documented)
  • Social Security, disability, or retirement income

Non-qualifying income typically includes:

  • Cash jobs with no paper trail
  • Recently started side gigs (under 2 years)
  • One-time or inconsistent bonuses
  • Venmo, PayPal, or Zelle deposits not reported on taxes

Even if you make a lot, if it's not documented, lenders won't count it for qualifying purposes. If you're unsure whether specific income counts, a lender can review your situation and tell you what you can use now — and what needs more time.


4. What Self-Employed Borrowers Need to Know

Self-employment adds complexity — but it doesn't disqualify you. Here's how it works:

Lenders use net income, not gross. If you earned $100,000 but wrote off $50,000, your qualifying income may only be $50,000.

Two years of tax returns is standard. Consistency matters — if income dropped from year one to year two, lenders may use the lower figure or average the two.

Upward trends help. If your income is growing and you've been self-employed for 2+ years, that positive trend can strengthen your application.

One year may be possible. Some lenders accept one year of returns if credit and financial reserves are strong.

Business structure matters. If you're structured as an S-corp or LLC, expect to provide:

  • K-1s
  • Business tax returns
  • Documentation of ownership percentage

The Bottom Line

Income doesn't need to be perfect — it needs to be documented and consistent. If you're unsure how your income situation fits into mortgage qualification, the best step is a direct conversation with a lender before you start searching.

RYAN: Let's talk about income. Because when it comes to buying a home, it's not just how much you make, but how you make it, how it's documented, and how consistent it is that really matters. I'm going to walk you through the four key things lenders look at when it comes to your income, so you can understand where you stand and what to expect when applying for a mortgage. Number one: What lenders look for. First up is stability and consistency. Most lenders want to see an average of 2 years of income history in the same field of work. Now, that doesn't mean you have to have the same job for two years, but there should be a consistent pattern. If you've changed jobs, but stayed in the same industry, that's typically going to be fine. If you've been going to school and now just graduated and got that first job, that's also typically going to be fine, especially where we can document that school history. Lenders are also looking for verifiable income. That means income that they can actually see on a W-2, a pay stub, tax returns, or official bank statements. If you're full-time and salaried, this is pretty straightforward. Hourly workers may need to show average hours worked over time, and part-time or variable income workers will often need to be documented over a longer period of time. Number two: Understanding debt-to-income ratios. DTI, or debt-to-income ratio, is one of the biggest factors in qualifying for a loan. Your DTI is the percentage of your monthly income that goes towards monthly debt payments. That includes car loans, student loans, credit card minimum payments, personal loans, and then obviously this new projected monthly mortgage payment. Here's how you calculate it: if you make $6,000 per month before taxes, and your total monthly debts, including this new mortgage payment, will be $2,400, your DTI is 40% — which is essentially $2,400 divided by $6,000. Most loan programs want your total DTI to be under 43 to 50%, which depends on the loan type. A lower DTI often means you qualify for a better loan or a larger purchase amount. But don't worry if yours is a little bit too high — we can often help you figure out ways to reduce it or adjust what you're looking for. Number three: Qualifying income versus non-qualifying income. Not all income can be used for a mortgage, even if it's real money in your account. Qualifying income includes full-time W-2 income, consistent hourly wages, verified part-time income, bonuses or commissions that are consistent over time, alimony or child support, social security, disability, or retirement income. Non-qualifying income usually includes cash jobs with no paper trail, recently started side gigs, one-time bonuses or inconsistent income, Venmo, PayPal deposits that are not claimed on your taxes. Even if you make a lot, if it's not documented, lenders won't count it — at least not for qualifying purposes. This is where we can help. If you're not sure whether something counts, reach out to us. We can review it and figure out what you can use now and what needs more time. Number four: What self-employed borrowers need to know. If you're self-employed, things work a little differently. Lenders usually look at the last 2 years of tax returns. And here's the key — they base your income on your net income, not on the gross. So if you've made $100,000 but wrote off $50,000, your qualifying income might only be $50,000. Consistency is also key. If your income dropped from one year to the next, they may average it or they may use the lower of the two. On the flip side, if your income is trending upwards and you've been self-employed for more than 2 years, that can help. Some lenders do allow for just one year of returns if your credit and reserves are strong. And if you're structured as an S-corp or LLC, we may also need your K-1s, your business tax returns, or documentation of ownership. So here's the bottom line. Income doesn't need to be perfect, but it does need to be documented and consistent. If you're unsure how your income fits into all this, you can download one of our free guides or, of course, reach out in the chat and we'll walk you through it together.

The Couple Who Bought Without a Job

A couple — second marriage, first home together — had almost nothing that looked like conventional qualification. He had no job. Her income barely registered. Through planning, an employment offer letter structure, and willingness to look beyond their geographic preferences, they found a home in Payson that turned out to be perfect in ways they couldn’t have predicted. He got a job in Nephi afterward — and the location of the home made it possible.

The Dream Home That Wasn't

A young engaged couple approved for just over $500,000 went to see their dream home. It was in terrible condition — $150,000 in repairs needed. They were defeated. Nikki pivoted them to a smaller, completely remodeled home with land to expand and a basement with a separate entrance for rental income. It wasn't as grand. But it required no repairs, had multiple future options, and was the smarter first chess move.
