Consequences of Less Than 20% Down

The minimum down payment required for a conventional loan is typically 3% of the home’s purchase price for qualified borrowers. This low down payment option is commonly available through programs designed for first-time homebuyers or borrowers with strong credit and stable income. However, not all applicants will qualify for the 3% option. Many conventional loans require 5% to 20% down, depending on credit score, debt-to-income ratio, and overall financial profile. If the down payment is less than 20%, private mortgage insurance (PMI) is usually required, which can be removed once sufficient equity is reached.

Yes, a conventional loan generally requires private mortgage insurance (PMI) if you put down less than 20 percent of the home’s purchase price. PMI protects the lender in case of default and is a standard requirement for low–down payment conventional loans. The cost of PMI depends on factors such as credit score, loan amount, and down payment size, and it is usually added to the monthly mortgage payment. One advantage of conventional loans is that PMI is not permanent—it can be canceled once you reach 20 percent equity based on the home’s value or original loan balance.

Conventional loans do not impose a single, strict maximum debt-to-income (DTI) ratio that guarantees approval for every borrower. Instead, DTI limits are flexible and largely determined by automated underwriting systems such as Desktop Underwriter (DU) or Loan Product Advisor (LPA). In many cases, a DTI of up to 45% is preferred, but approvals can extend to 50% or higher when the borrower has strong compensating factors. These factors may include a high credit score, significant cash reserves, stable income, or a larger down payment, allowing more flexibility rather than a rigid cutoff.

Yes, you generally have to pay mortgage insurance on a conventional loan if your down payment is less than 20%. This insurance is called Private Mortgage Insurance (PMI), and it protects the lender—not the borrower—in case of default. PMI is usually added to your monthly mortgage payment, though in some cases it can be paid upfront or built into the loan. The good news is that PMI on a conventional loan is not permanent. Once you reach 20% home equity, you can request its removal, and it is automatically canceled when you reach 22% equity, assuming payments are current.

For conventional mortgage loans, the lender must obtain a primary mortgage insurance policy if the loan-to-value (LTV) ratio is greater than 80 percent at the time of purchase or securitization. This requirement ensures that the lender is protected against loss in the event of borrower default when the borrower has limited equity in the property. Acceptable forms of credit enhancement include policies from approved private mortgage insurers. If a borrower puts down less than 20 percent, this coverage is mandatory unless another charter-compliant form of credit enhancement is provided.

For conventional loans with LTV ratios greater than 80 percent, the required mortgage insurance coverage varies by LTV tier. For fixed-rate loans with terms up to 20 years, coverage is 6 percent for LTVs of 80.01-85%, 12 percent for 85.01-90%, 25 percent for 90.01-95%, and 35 percent for 95.01-97%. For fixed-rate loans with terms greater than 20 years, the standard coverage requirements are 12 percent, 25 percent, 30 percent, and 35 percent respectively for the same LTV tiers. Lenders may choose minimum coverage levels, but this typically results in loan-level price adjustments.

Yes, borrowers can utilize subordinate financing, such as a Community Seconds loan, to cover the down payment. Fannie Mae permits a combined loan-to-value (CLTV) ratio of up to 105 percent when a Community Seconds loan is used. This allows a borrower to obtain a first mortgage with a high LTV (e.g., 97 percent) and use the subordinate financing for the remaining funds or closing costs, effectively reducing the need for personal cash at closing. The subordinate financing must meet specific eligibility requirements regarding interest rates and repayment terms.

Yes, Fannie Mae offers the HomeReady mortgage and standard purchase transactions for first-time homebuyers that allow for a maximum LTV of 97 percent, meaning a down payment of as little as 3 percent. Similarly, Freddie Mac’s Home Possible and HomeOne mortgages allow LTV ratios up to 97 percent for one-unit principal residences. These programs are designed to assist creditworthy borrowers who may not have the funds for a larger down payment. For HomeReady, the borrower is not required to use their own funds for this contribution; it can come from gifts or grants.

Yes, borrowers can finance the mortgage insurance premium into the loan amount for one-unit principal residences. For Fannie Mae, this is permissible for purchase or limited cash-out refinance transactions. The loan amount including the financed premium cannot exceed the applicable loan limits, and the gross LTV ratio (calculated with the financed premium) generally must not exceed 95 percent, or 97 percent for HomeReady loans. Freddie Mac also allows financed mortgage insurance premiums, provided the gross LTV ratio does not exceed 95 percent (97% for Home Possible and HomeOne).

Yes, gift funds from acceptable donors, such as family members or charitable organizations, can be used for the down payment. For conventional loans on one-unit principal residences, if the LTV is greater than 80 percent, a minimum borrower contribution from their own funds is generally not required, meaning the entire down payment can come from a gift. However, for two- to four-unit properties with LTVs greater than 80 percent, the borrower must contribute at least 5 percent from their own funds. Gifts must be properly documented with a gift letter.
