What Is a Conventional Loan?
A conventional loan is a mortgage that is not insured or guaranteed by the federal government. Lenders fund these loans with their own capital or sell them on the secondary market, so they follow standard underwriting guidelines.
Eligibility Basics for First‑Time Buyers
To qualify, you’ll need a steady income, a credit history that shows you can manage debt, and enough cash for a down payment and closing costs. Most lenders look for a credit score of at least 620, although a higher score can improve your rate and reduce costs.
Down Payment and Private Mortgage Insurance (PMI)
You can put down as little as 3% of the home’s price, but if you contribute less than 20%, the lender will usually require PMI. This insurance protects the lender if you default, and it adds to your monthly payment until you reach 20% equity.
Debt‑to‑Income Ratio (DTI) and Income Verification
Lenders calculate DTI by adding up all your monthly debt obligations—including the projected mortgage payment—and dividing that total by your gross monthly income. Keeping the DTI at 45% or lower helps you stay within most conventional loan limits.
Wisconsin‑Specific Considerations
- Closing in Wisconsin is often performed by an attorney, who handles the deed, title search, and settlement. This differs from many states where a title‑company may perform those duties.
- The Wisconsin Housing and Economic Development Authority (WHEDA) runs several first‑time‑buyer programs that can provide down‑payment assistance, low‑interest loans, or favorable terms for conventional financing.
How to Apply
Start by gathering recent pay stubs, tax returns, bank statements, and a list of your debts. Contact a lender who offers conventional loans and ask about any Wisconsin‑specific programs they support. The lender will run a credit check, verify your income, and calculate your DTI before issuing a pre‑approval.

FAQ
What is private mortgage insurance (PMI) and when do I need it?
PMI is insurance that protects the lender if you stop making payments. It is required on conventional loans when your down payment is less than 20% of the home’s purchase price. The premium is added to your monthly mortgage payment and usually drops off once you reach 20% equity.
How does WHEDA assistance work for first‑time buyers?
WHEDA offers several programs, such as down‑payment assistance loans and low‑interest mortgage options. Eligibility typically includes income limits, purchase price caps, and the requirement that the home be your primary residence. Applying through a WHEDA‑approved lender can streamline the process.
Can I use a gift from a family member for my down payment?
Yes, most conventional lenders allow gift funds for the down payment, but the donor must provide a signed gift letter stating the money is a gift and does not need to be repaid. The lender may also require proof that the donor has sufficient assets to cover the gift.
What documents will the lender need to process my loan?
Typical documents include recent pay stubs, W‑2s or 1099s, federal tax returns for the past two years, bank statements, proof of any additional assets, and a list of current debts. If you’re using a Wisconsin assistance program, additional paperwork may be required.
How long does the conventional loan approval process usually take?
From application to closing, the process often takes 30 to 45 days, assuming all documentation is submitted promptly and there are no major underwriting issues. Factors that can extend the timeline include appraisal delays, title searches, or additional verification requests.
