Key takeaways
- Minimum credit score: 620 for most conventional loans
- Typical down payment: 3%–5% (3% often required for first‑time buyers with mortgage insurance)
- Maximum debt‑to‑income (DTI) ratio: 45% (higher may be allowed with strong compensating factors)
- Self‑employment documentation: two years of personal and business tax returns plus a year‑to‑date profit and loss statement
- Conforming loan limit in Wisconsin: up to $726,200 in most counties, higher in designated high‑cost areas
Conventional loans are private‑sector mortgages that are not insured or guaranteed by the federal government. Because they rely on the lender’s own underwriting standards, borrowers need to demonstrate solid credit, stable income, and enough cash for a down payment.
Key requirements for self‑employed borrowers
- Credit score. Most conventional programs require a minimum score of 620. A higher score can offset a higher debt‑to‑income ratio or a smaller down payment because it signals lower risk to the lender.
- Debt‑to‑income (DTI) ratio. Lenders typically cap DTI at 45% of gross monthly income. If you have a strong credit history, significant cash reserves, or a large down payment, the cap may be stretched to 50% or even 55%.
- Down payment. The baseline is 3% of the purchase price for first‑time homebuyers who qualify for private mortgage insurance (PMI). Many borrowers aim for 5% to reduce PMI costs and improve loan terms.
- Documentation of self‑employment. Expect to provide two full years of personal and business tax returns, along with a year‑to‑date profit and loss (P&L) statement. Lenders use these documents to verify that your net self‑employment income is stable and sufficient to cover the mortgage.
Wisconsin‑specific considerations
- Most Wisconsin transactions close with an attorney rather than a title‑company. The attorney will review the deed, handle the escrow, and ensure the title is clear before recording the sale.
- The state offers a first‑time homebuyer assistance program (Wisconsin Homeownership Partnership) that can provide down‑payment help or low‑interest loans. These funds can be combined with a conventional loan, but the lender will need to verify the source of the assistance.
Loan limits are set annually by the Federal Housing Finance Agency. In Wisconsin, the conforming loan limit is generally $726,200 for most counties, with a higher ceiling in designated high‑cost areas such as parts of Milwaukee.
Because conventional loans are not government‑backed, they often have stricter underwriting. Meeting the credit, DTI, and documentation standards improves your chances of approval and can result in better interest rates and lower fees.

FAQ
Can I qualify for a conventional loan if I have only one year of self‑employment?
Most lenders require at least two years of self‑employment documentation for a conventional loan. Some may consider a strong credit profile and large cash reserves as compensating factors, but approval is less common with only one year of income history.
How does the Wisconsin Homeownership Partnership program work with a conventional loan?
The program can provide down‑payment assistance or a low‑interest loan that you can combine with a conventional mortgage. The lender will need to verify the source of the assistance and ensure it meets the program’s eligibility criteria, such as income limits and first‑time buyer status.
Do I need a co‑signer if my credit score is below 620?
A credit score below 620 makes conventional loan approval difficult, but some lenders may still consider your application if a co‑signer with strong credit is added. The co‑signer becomes equally responsible for the loan, which can improve your DTI and overall risk profile.
What role does an attorney play in a Wisconsin closing?
In Wisconsin, an attorney typically conducts the title search, prepares and reviews the deed and closing documents, manages the escrow funds, and records the transaction with the county. This differs from many states where a title‑company handles these tasks.
How does private mortgage insurance (PMI) affect my monthly payment?
If you put down less than 20% of the purchase price, most conventional loans require PMI. PMI is an additional monthly fee that protects the lender if you default. The cost varies based on loan‑to‑value ratio and credit score, but it usually ranges from 0.3% to 1.5% of the loan amount per year.
