Conventional Loan Pros and Cons for Illinois Homebuyers

Reviewed by the HomeMath editorial team Updated 2026-08-04

Key takeaways

Conventional loans allow down payments as low as 3% for first-time buyers, compared to the 3.5% minimum for FHA loans.
Private Mortgage Insurance (PMI) on conventional loans automatically terminates once you reach 22% equity, unlike FHA insurance which often stays for the life of the loan.
Illinois real estate transactions typically require an attorney for the contract review and closing process, which adds a layer of legal protection but also an additional professional fee.

A conventional loan is a mortgage not backed by any federal government agency, such as the FHA, VA, or USDA. Instead, these loans are funded by private lenders and follow guidelines set by government-sponsored enterprises, Fannie Mae and Freddie Mac. Because they lack government backing, lenders view these loans as higher risk, which is why the qualification requirements are generally stricter than government-backed alternatives.

The Advantages of Conventional Financing

One primary benefit is the flexibility of Private Mortgage Insurance (PMI). On a conventional loan, PMI is required if your down payment is less than 20% of the home's purchase price. However, once your loan-to-value ratio reaches 78%, the lender is legally required to cancel the PMI. This provides a clear path to lower monthly payments as you build equity.

Conventional loans also offer more flexibility regarding property condition. Government-backed loans often require strict property appraisals that mandate specific repairs before a loan can close. Conventional loans are generally more lenient, making them a preferred choice for sellers who may be wary of the repair demands often associated with FHA or VA offers.

The Challenges and Requirements

To qualify for conventional financing, you generally need a higher credit score compared to FHA loans. Lenders typically look for a score of 620 or higher, though a higher score can significantly impact your interest rate and the cost of your PMI. Additionally, your debt-to-income (DTI) ratio is closely scrutinized; while limits can vary, lenders generally prefer a DTI below 43% to ensure you have enough residual income to handle homeownership costs.

In Illinois, the closing process involves unique structural requirements. Unlike some states that rely exclusively on title companies, Illinois is an 'attorney state.' This means you will typically hire a real estate attorney to review your purchase contract, handle the title work, and facilitate the closing. While this adds a cost, it ensures your interests are protected during the legal transfer of property.

Illinois-Specific Considerations

The Illinois Housing Development Authority (IHDA) offers several programs aimed at first-time homebuyers, including down payment assistance and tax credits. These programs can often be paired with conventional loans to make homeownership more accessible. Because Illinois has relatively high property taxes compared to the national average, your lender will include these taxes in your monthly escrow payment. It is critical to account for these local tax burdens when calculating your total monthly housing budget to ensure the payment remains sustainable over the long term.

You should consult with a licensed mortgage loan officer and a qualified Illinois real estate attorney to confirm current requirements and program eligibility for your specific financial situation.

FAQ

What is the minimum credit score for a conventional loan in Illinois?

While some lenders may approve scores as low as 620, most conventional programs require a score of 620 or higher for approval. Borrowers with scores above 740 typically qualify for the most favorable interest rates and lower PMI premiums.

Do I need an attorney for a home closing in Illinois?

Yes, Illinois is widely considered an attorney-state, meaning it is standard practice to hire a lawyer to represent you during the contract review, inspection negotiation, and closing. Their role is to protect your legal interests and ensure the title is clear, which is distinct from the duties of your lender or real estate agent.

How does PMI differ between a conventional loan and an FHA loan?

On a conventional loan, PMI can be removed once you reach 22% equity in your home. In contrast, FHA loans require an annual mortgage insurance premium that often remains for the entire life of the loan if you put down less than 10%.

Can I use Illinois down payment assistance with a conventional loan?

Yes, many IHDA programs are designed to work alongside conventional financing. You must meet specific income and purchase price limits set by the state to qualify for these assistance funds.
