Many self-employed buyers are approved for a smaller loan than their income supports.
One solution that may unlock more borrowing power is a bank statement mortgage.

What Is a Bank Statement Loan?

A bank statement loan is a type of non-QM mortgage (non-Qualified Mortgage) that lets you qualify using 12 or 24 months of bank deposits instead of tax returns. Rather than looking at your net taxable income, the lender averages your deposits and subtracts a standard expense factor for your industry to arrive at your qualifying income.

This exists to solve one specific problem: your tax return doesn't reflect your real income. That's common if you own a business, work as a 1099 contractor, or draw commission income, since deductions and reinvestment lower the income that shows up on paper. Colorado has a lot of contractors, consultants, and small business owners, so this situation comes up constantly here, especially around Denver and Boulder.

Here's How These Loans Work

See below how a $160,000 earner is underwritten two different methods:

SAME BORROWER. 2 WAYS TO QUALIFY
Conventional Self-Employed Underwrite
Gross income (Sched. C, 1120-S, 1120) $160,000
Net income after tax deductions$84,000
Monthly qualifying income$7,000
Maximum DTI45%
Maximum loan~$420,000
Bank Statement Underwrite
12-months of deposits$160,000
Net income after expense factor of 20%$128,000
Monthly qualifying income$10,666
Maximum DTI50%
Maximum loan~$725,000
Sample scenario assumes a 20% down payment, 6.75% fixed interest rate, 720 credit, and zero monthly debts. Your actual qualifying income and purchase price will depend on your credit scores, monthly debts, and specific lender guidelines.

The gap exists because a CPA's deductions are based on your actual write-offs, which can run well past what a lender's flat expense factor accounts for. The expense factor itself depends on your industry: a consultant with low overhead might see 10% to 15%, while a contractor operating trucks and crews might see 40% or higher.

The choice between 12 and 24 months usually comes down to rate and consistency. Lenders often price 24-month programs slightly better, but you'll need at least two years in the same line of work to qualify for one. If you've been self-employed for a shorter stretch, the 12-month program is usually your only option.

The result is earnings that are genuinely strong on paper look weak to a conventional loan underwriter. This shows up often in competitive markets like Denver Central, Cherry Creek, Boulder's Table Mesa, and Mapleton Hill, where that mismatch can shrink your buying power or slow down your approval.

Who May Qualify for this Self-Employed Loan?

Bank statement loans work well for self-employed professionals whose work generates consistent deposits, even when the paperwork doesn't show it:

If your CPA maximizes deductions to manage your tax bill, a bank statement loan is usually still your best option. Although, a CPA-prepared profit and loss statement mortgage tends to work better instead when your bookkeeping is clean and your deposit history is inconsistent. The reason is the program relies on your P&L rather than month-to-month deposit averaging.

Here's a Couple of Real World Examples:

Solo Independent Contractor

Diego runs his own construction business. No employees, no office lease, just him and his crew of sub-contractors. His tax return looks thin once his vehicle and equipment write-offs come out, even though his bank deposits tell a completely different story.

Solution: Using 24 months of bank statements, the lender averaged his deposits and qualified him for a home near Wash Park without asking him to change how he does his books.

Small Business Owner With Employees

Samantha owns a small design studio in LoDo with three employees and a leased office space. The business brings in steady revenue, but reinvesting in staff, software, and rent keeps her taxable income low enough that a conventional lender turned her down.

Solution: Twenty-four months of business bank statements showed her actual cash flow. That was enough for her to qualify for a condo loan without changing how she runs the business.

Why Applications Get Denied?

Bank statement loans are designed to work around tax-return limitations, but they come with their own underwriting quirks that trip up applicants in three common ways:

How To Avoid Common Reasons for Denial?

Most bank statement loan denials come down to deposit patterns that are hard for an underwriter to verify income. Keeping your business income in one dedicated account and avoiding large unexplained transfers goes a long way toward a clean approval.

Common Bank Statement Program Questions

Why do lenders apply an expense ratio to bank statement loans?+
Because deposits alone don’t reflect profit. The expense ratio helps lenders estimate what portion of revenue remains after normal business costs.
Which businesses usually have lower expense factors?+
Service- and commission-based businesses tend to qualify more easily. These include consultants, independent agents, remote professionals, and solo practitioners with limited overhead.
Which businesses face higher expense factors?+
Industries that depend on labor, equipment, inventory, or vehicles such as construction, restaurants, retail, or transportation usually receive higher expense adjustments. For these businesses, most lenders will apply a minimum of 30-35% expense factor. We have an alternative program to use when that happens.
Can I use a bank statement loan to buy a condo or multi-unit property in Denver or Boulder?+
Yes. Bank statement loans can be used to finance primary residences, second homes, and investment properties including condos, duplexes, and triplexes. Lenders may require additional documentation for condos (HOA certification) and multi-unit properties (rental income payments for the last two months), especially in higher-cost neighborhoods like Cherry Creek, Hilltop, or Mapleton Hill.
Can a W 2 co-borrower be added to a bank statement loan?+
Absolutely. Many borrowers in Denver and Boulder pair a self-employed primary applicant with a W 2 co-borrower to strengthen income documentation or credit profile. Lenders will combine income from the W 2 co-borrower with bank statement deposits when calculating qualifying income, which can improve approval odds or reduce down payment requirements.
How long must I be self-employed to qualify for a bank statement loan in Colorado?+
Most programs require at least 12 months of consistent self-employment in the same business or line of work. Some lenders prefer 24 months, particularly for larger loans or luxury properties in Denver and Boulder. Demonstrating continuity of income through bank statements is the key factor.
Are there minimum credit score or down payment requirements?+
Yes. Most Denver and Boulder bank statement programs require credit scores starting around 660–680. Down payments range from 10% to 20% depending on property type, loan amount, credit score, and documentation. 10-15-percent down payments carry higher rates and require 740 or higher credit. Cash reserves may also be requested for larger loans or higher-risk properties.
What types of self-employment income are accepted?+
Lenders accept a variety of income sources documented via bank statements, including checks, cash deposits(depending on the business), ACH, paypal, Venmo, square, freelance work, and small business owner income as long as speciifc ones can be sourced. Consistency and continuity of deposits are critical to demonstrate qualifying income.
Can I use a bank statement loan to refinance an existing mortgage in Denver or Boulder?+
Yes. Self-employed borrowers often use bank statement refinancing to better reflect true income, access equity, or restructure loans when conventional refinancing options are limited due to low reported taxable income.
Do lenders look at personal or business bank statements?+
Both personal and business "checking" accounts are used, not savings. Lenders average deposits over a 12 or 24 month period minus an expense factor you confirm from your tax professional or the lenders uses their own to establish qualifying monthly income. The combination of accounts should demonstrate consistent, sustainable cash flow that supports the proposed mortgage payment.
