Income Requirements for a Conventional Loan in Wisconsin

Reviewed by the HomeMath editorial team Updated 2026-08-06

Key takeaways

Debt‑to‑income ratio generally must be 43% or lower
Minimum credit score usually 620 for a conventional loan
Lenders typically require at least two years of steady, documented income

Conventional loans are private‑sector mortgages that aren’t insured or guaranteed by the government. In Wisconsin, the income criteria are similar to most states, but local practices such as attorney‑handled closings and state‑specific assistance programs can influence the documentation you’ll need.

Income Documentation

Lenders want to see that your earnings are reliable and likely to continue for the life of the loan. Common documents include:

Recent pay stubs (usually the last 30 days)
Two years of W‑2 forms or 1099s for self‑employed borrowers
Federal tax returns (typically the most recent two years)
Profit‑and‑loss statements if you own a business

Consistent employment for at least two years helps the lender assess stability; gaps may be acceptable if you can show a solid reason, such as returning from school or a temporary layoff.

Debt‑to‑Income (DTI) Ratio

The DTI ratio compares your monthly debt payments to your gross monthly income. Conventional lenders usually set a maximum DTI of about 43%, although some may allow higher ratios with compensating factors like a large cash reserve or a strong credit score. The rule exists to ensure borrowers can comfortably meet mortgage payments even if other expenses rise.

Credit Score Requirements

A credit score of at least 620 is the baseline for most conventional loans. Higher scores can qualify you for better interest rates and may give lenders more flexibility with DTI limits. Credit scores reflect your past borrowing behavior, helping lenders gauge the risk of future default.

Wisconsin‑Specific Considerations

In Wisconsin, many home purchases involve an attorney who oversees the closing process, which can affect the timing of document collection. Additionally, the Wisconsin Housing and Economic Development Authority (WHEDA) offers down‑payment assistance and affordable‑mortgage programs for first‑time buyers. Participation in a WHEDA program doesn’t change the basic income thresholds, but it can provide extra cash that helps you meet lender requirements for reserves.

FAQ

What if my debt‑to‑income ratio is higher than 43%?

Some lenders may still approve you if you have a very high credit score, substantial cash reserves, or a large down payment. However, a higher DTI increases perceived risk and may result in a higher interest rate or a request for additional documentation.

Do I need to provide tax returns if I’m a salaried employee?

Yes. Most lenders require the last two years of federal tax returns even for salaried borrowers, because they help verify the consistency of your reported income and reveal any additional sources of earnings.

How does WHEDA’s first‑time‑buyer assistance affect income requirements?

WHEDA assistance primarily adds funds for down payment and closing costs; it does not lower the lender’s DTI or credit‑score thresholds. However, the extra cash can improve your overall financial profile, making it easier to meet reserve requirements.

Can a co‑borrower help me meet the income criteria?

Yes. Adding a co‑borrower combines both incomes and debts for DTI calculation, which can lower the overall ratio and strengthen the loan application, provided the co‑borrower meets the lender’s credit and employment standards.
