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.

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.

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.

But it required no repairs, had multiple future options, and was the smarter first chess move.
