The Quick Read: If your commissions dropped, an income-based mortgage will usually shrink what you can borrow, but a DSCR loan on a rental property qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. Your paycheck matters far less on that path. Credit, leverage, and reserves still matter.
- Income-based lenders look backward at one or two years, so a down year can follow you through several applications.
- A DSCR loan is for investment properties only. A home you will live in still goes through income-based underwriting.
- Most files land at 75%-80% LTV on a purchase, with credit typically around 660 and 700+ for the strongest tiers.
- Select programs start at 1.00 coverage. Coverage below 1.00 is available through select lenders in the network, with leverage and terms adjusted.
- Reserves are commonly around 6 months of PITIA, and a slump that drains your savings can still hurt the file.
Commission earners get hit twice in a bad year. The income drops, and the lender’s math punishes the drop more than the drop alone deserves. This article walks through how that happens, which loan structures sidestep it, and where those structures stop helping.

How Does a Lender Count Commission Income?
A lender counts commission income by documenting a history, averaging it, and then testing the trend. Two years of traditional personal-income documentation is the usual starting point. A falling trend can pull the qualifying income figure down toward the lowest recent figure, or remove the income entirely.
Here is the three-step method, in plain terms:
1. History. The lender wants a documented record of commission pay. Practitioners generally describe a two-year history as the norm.
2. Averaging. The two years get blended into one monthly figure. For self-employed or fully commissioned earners, lenders generally look at net income after expenses, not gross commissions.
3. Trend check. This is where a down year hurts. When the latest year is below the prior one, underwriters may use the lower figure instead of the average. If the decline is steep, they may leave the commission income out.
A borrower with a base salary and commission often sees the base count while the commission gets averaged and trend-tested. A written explanation of the drop, backed by documents, is typically requested for a material decline.
These are common underwriting practices, not a single fixed rulebook. The underlying federal rule does not prescribe one underwriting model, so how a lender trims commission income is a lender or program choice. The CFPB’s small-entity compliance guide says the rule does not mandate a specific method.
Why Does a Down Year Cost So Much Borrowing Power?
A lower qualifying income raises your debt-to-income ratio (DTI), which is your monthly debts divided by your monthly income. When the income side shrinks, the same debts take up a bigger share. Lenders then approve a smaller loan or decline the file.
Picture two years of commission pay where the second year drops. The average looks decent. The lender may skip the average and use the lower year. Your DTI jumps, and the home you qualified for last year is out of reach this year, even though your existing rentals are performing.
That is the real cost of a down year. It is not the income you lost. It is the borrowing power attached to the income the lender is willing to count.
What Are the Three Ways to Qualify?
Three underwriting paths exist, and they differ in what they treat as the source of repayment.
| Path | What repays the loan | What a down year does |
|---|---|---|
| Income-based (conventional style) | Your documented income | Lowers or removes commission income |
| Alternative-income non-QM | Your income, shown another way | Weaker deposits lower qualifying income |
| DSCR | The property’s rent | Matters little to approval |
Non-QM means a loan that does not meet the standard “qualified mortgage” definition. It is a category, not a warning label. Alternative-income programs use bank-statement deposits, 1099 income, CPA-prepared profit-and-loss statements, or asset depletion. They treat your income as the repayment source, just verified differently. A weak run of deposits in a down year lowers qualifying income there too.
If you want to see how those routes work in detail, Lendmire has a piece How to Qualify for a Bank Statement Loan With One Declining Deposit Year and another on qualifying on a CPA P&L loan after one declining year.
The third path is the one that changes the question. A DSCR loan compares rent to the full monthly housing payment: principal, interest, taxes, insurance, and any HOA dues. That payment total is called PITIA. DSCR stands for debt service coverage ratio. A ratio of 1.00 means the rent just covers the payment.
How Does DSCR Underwriting Actually Work?
DSCR underwriting qualifies the property. The lender divides rent by PITIA, checks the ratio against its program floor, and then reviews your credit, leverage, and reserves. Commission history, W-2s, traditional personal-income documentation, and employment verification are typically not part of the file.
Step by step:
1. Rent is established. An appraiser’s rent schedule does this on a purchase or refinance: Form 1007 for single-family, Form 1025 for two-to-four units. An existing lease can also support it.
2. The ratio is calculated. Monthly rent divided by monthly PITIA. Rent that comfortably covers the payment produces a ratio above 1.00.
3. The borrower is reviewed. Credit score, loan-to-value (LTV, the loan as a share of the property’s value), borrower experience, and reserves all count.
4. The property is reviewed. It must be an eligible type.
Across the wholesale network Lendmire works with, 1.00 is where select programs start. It is a floor for specific programs, not a universal standard. Stronger ratios open better pricing and leverage. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted.
DSCR loans are designed for non-owner-occupied investment properties. Because they are business-purpose investor loans, they are reviewed differently from a standard owner-occupied mortgage. That is the reason your commission slump is not the center of the file.
One caution. Clearing 1.00 is not the same as positive cash flow. The ratio compares rent to PITIA only. Repairs, vacancy, management, utilities, and capital expenses sit outside the calculation. Budget for them separately.
What Program Numbers Should You Expect?
Most DSCR files across the network sit in familiar ranges. Treat these as typical guidance from select lenders, not promises. Every file is underwritten individually.
| Factor | Typical range |
|---|---|
| Purchase LTV | 75%-80% (20%-25% down) |
| High-leverage purchase | Up to 85% LTV, roughly 700+ score |
| Cash-out refinance | Up to about 75% LTV, about 6 months seasoning |
| Credit | 620 floor in parts of the network; most want about 660 |
| Strongest tiers | 700+ |
| Loan size | Up to $3,000,000 on standard programs |
| Reserves | Commonly about 6 months PITIA |
Reserves are the cash you hold after closing. They vary by lender, leverage, loan size, and transaction type. Conservative rate-and-term files at modest leverage under $1,500,000 can see reserves waived, and loans above that size typically step up to about 9 months.
Seasoning is the waiting period between buying a property and cashing out on it. Loans above $2,500,000 generally stick to 30-year fixed structures. Extended terms and interest-only periods are available through select lenders, and ARM structures exist for investors who want them.
For commission earners, credit and reserves deserve the most attention. Your income is not on the page, so your score and your cash cushion carry more of the file.
Where Does the General Rule Break?
DSCR helps most when the problem is your income, and helps least when the problem is something else. These are the edge cases that catch people.
You are buying a home to live in. A DSCR loan is for investment properties only. A commission earner buying a primary residence still faces income-based underwriting and the trend test described above.
A slump drained your savings. The loan does not look at your pay, but it does look at liquidity. If a bad year burned through your cash, reserves can become the sticking point. That is an inference from how the files work, not a published rule.
The property is ineligible. Manufactured homes (single- and double-wide), log homes, and barndominiums are not offered in the network’s DSCR programs.
The cash-out is for personal spending. The business-purpose treatment turns on the loan’s primary purpose, and the lender determines that case by case. The CFPB’s exemption rule says the creditor decides primary purpose. Pulling cash from a rental to cover personal bills can raise questions. Confirm how the program treats your use of proceeds before you assume anything.
The rent is thin. If coverage lands below 1.00, you are looking at the select-lender path with leverage and terms adjusted. A larger down payment lowers the payment and can lift the ratio, but it never erases leverage caps, credit floors, reserve rules, or property eligibility. The strongest files clear both tests: enough equity and enough rental coverage.
You are planning to scale. Conventional financing is generally limited in how many financed properties one borrower can hold, which pushes many investors toward DSCR as the portfolio grows. Conventional can still make sense when you qualify, since it may price better. A DSCR file trades some of that for flexibility.
What Does the Decision Look Like in Practice?
The decision comes down to what you are buying and what your income looks like on paper. Run these questions in order.
Is it a rental, or a home you will live in? If you will live in it, expect income-based underwriting. If it is a rental, DSCR is on the table.
Does the rent cover the payment? Ask for a rent estimate before you commit. At or above 1.00 opens the standard select programs. Below it, ask about the select-lender sub-1.00 path.
Are your credit and reserves ready? Aim for the 660 range or better, and 700+ if you want the strongest leverage. Keep about 6 months of PITIA liquid.
What is the trade? Investors commonly cite fees, pricing, and prepayment penalties as the main drawbacks of DSCR financing. Weigh those against what a smaller conventional loan would cost you in lost opportunity.
Now a short timeline for a commission earner heading into an application:
- Twelve months out: protect your score, build reserves, and avoid large new debt.
- Six months out: line up a rent estimate on the target property and compare programs.
- Three months out: keep accounts stable. Do not open new credit lines.
- Right before applying: do not move cash around in ways you cannot explain.
A DSCR file also pairs naturally with a bigger plan. The complete DSCR loans guide covers the full set of programs, and a broker can compare several lenders’ guidelines at once instead of making you guess which one fits.
Why the Federal Rule Matters Here
Income-based mortgages run under a federal ability-to-repay rule. The CFPB explains that lenders must generally document and consider your income, assets, employment, credit history, and monthly expenses. Because “reasonably expected income” is part of the test, a sharp commission drop is a direct underwriting issue, not just lender taste.
Business-purpose investor loans are reviewed differently. That is the structural reason a DSCR file does not ask for your commission history.
Key Terms Defined
DSCR (debt service coverage ratio): Monthly rent divided by the full monthly property payment. A result of 1.00 means rent just covers it.
PITIA: Principal, interest, taxes, insurance, and any HOA dues. It is the full monthly housing payment.
LTV (loan-to-value): The loan balance as a percentage of the property’s value.
DTI (debt-to-income): Your monthly debts divided by your monthly income. Income-based lenders lean on it heavily.
Non-QM: A loan outside the standard qualified-mortgage definition. It is a category, not a quality judgment.
Reserves: Cash or liquid assets you hold after closing, usually counted in months of PITIA.
Seasoning: The waiting period between acquiring a property and refinancing it.
Frequently Asked Questions
Will one bad commission year really hurt a conventional application?
Often, yes. Underwriters may use the lower recent figure instead of the two-year average, or drop commission income if the decline is large. These are common practices rather than a single rule, and they vary by lender and program. A written explanation with supporting documents usually helps.
Do I need to show my commission income for a DSCR loan?
Not typically. The file qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. Credit, leverage, experience, and reserves still count, so a DSCR loan is not automatic.
Can I use a DSCR loan to buy my own home?
No. These loans are for investment properties. A home you will live in goes through income-based underwriting, where a commission decline matters directly.
Does a bigger down payment fix a weak file?
It helps the ratio and lowers the payment, but it does not override credit floors, leverage caps, reserve rules, or property eligibility. The best files show enough equity and enough rent coverage together.
Is DSCR coverage the same as positive cash flow?
No. Coverage compares rent to PITIA only. Repairs, vacancy, management, utilities, and capital expenses are not in the calculation, so plan for them separately.
If you are buying or refinancing a rental property and want to see how the numbers work, Lendmire can help you compare DSCR loan options based on the property income, credit profile, leverage, and investor goals. Tax treatment can depend on how the funds are used and how the property is held; investors should keep clear records and speak with a qualified tax professional before relying on any deduction. Program details change and every file is underwritten individually, so nothing here is a commitment to lend.
