Conventional Loan Guide for First-Time Buyers in Missouri

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

Key takeaways

Most first-time buyers can qualify for a conventional loan with a down payment as low as 3% of the purchase price.
Credit scores typically need to be at least 620, though higher scores significantly improve your interest rate and mortgage insurance costs.
Private Mortgage Insurance (PMI) is required if you put down less than 20%, but it is automatically removed once you reach 22% equity.
Missouri Housing Development Commission (MHDC) offers down payment assistance programs specifically designed to help first-time buyers bridge the gap.

A conventional loan is a mortgage not backed by the federal government, such as FHA or VA loans. Because these loans are held by private lenders and often sold to government-sponsored enterprises like Fannie Mae or Freddie Mac, they follow standardized guidelines. For first-time buyers in Missouri, this is often the preferred path when credit is stable and the buyer has at least a modest down payment saved.

The Role of Credit and Debt-to-Income (DTI)

Lenders evaluate your eligibility primarily through your credit score and your debt-to-income ratio. While a score of 620 is often the minimum threshold, conventional lenders prefer scores above 700 to offer the most competitive interest rates. Your DTI ratio—which compares your monthly debt payments to your gross monthly income—is also critical. Most lenders prefer a total DTI of 43% or lower, though some programs allow for higher ratios if you have significant cash reserves.

Down Payments and Private Mortgage Insurance

One of the biggest misconceptions about conventional loans is that they always require a 20% down payment. In reality, first-time buyers can put down as little as 3%. However, if you put down less than 20%, you will be required to pay Private Mortgage Insurance (PMI). This monthly fee protects the lender in the event of default. Unlike FHA loans, where mortgage insurance can stay for the life of the loan, PMI on a conventional loan is temporary. It will automatically drop off once your loan balance reaches 78% of the home's original appraised value.

Missouri-Specific Resources

Missouri supports first-time homeowners through the Missouri Housing Development Commission (MHDC). They offer programs such as the 'First Place' loan, which provides down payment and closing cost assistance to eligible buyers. Because Missouri is a state that relies heavily on title companies rather than attorneys for real estate closings, the process can be relatively streamlined compared to states with mandatory attorney involvement. Working with a lender who is familiar with MHDC programs can help you determine if you qualify for these grants or low-interest second mortgages to cover your initial move-in costs.

The Closing Process

Once you are under contract, the lender will order an appraisal to ensure the home's value justifies the loan amount. In Missouri, you will also work with a title company to perform a title search, ensuring there are no liens or ownership disputes attached to the property. Because conventional loans are subject to national underwriting standards, the documentation requirements—such as pay stubs, tax returns, and bank statements—are consistent across the state.

FAQ

Is it better to get an FHA loan or a conventional loan in Missouri?

Conventional loans are generally better if you have a strong credit score, as they offer lower mortgage insurance costs and the ability to cancel that insurance later. FHA loans may be more accessible if your credit score is lower or your debt-to-income ratio is higher, but they carry permanent mortgage insurance for the life of the loan.

Do I need a 20% down payment to avoid PMI?

Yes, putting down 20% is the standard way to avoid PMI on a conventional loan. If you cannot reach 20%, you will pay PMI monthly, but it is not a permanent cost and will be removed once your equity hits the required threshold.

Can I use gift money for my down payment?

Yes, conventional loan programs allow first-time buyers to use gift funds from family members to cover all or part of the down payment. You will need a 'gift letter' signed by the donor stating that the money does not need to be repaid.

What is the 'conforming loan limit' and does it affect me?

The conforming loan limit is the maximum dollar amount for a mortgage that Fannie Mae or Freddie Mac will buy. If your loan exceeds this limit, it is classified as a 'jumbo loan,' which typically requires higher credit scores and larger down payments.
