Conventional Loan Requirements for a First-Time Buyer With Little Down

The Quick Read: A first-time buyer can buy a primary residence with as little as 3% down on a conventional loan, and the leverage is capped at 97% of the home’s value. The loan must be a fixed rate on a one-unit home, and at least one borrower must be a first-time buyer. Most files run through automated underwriting, with a total debt ratio ceiling of 50%. Mortgage insurance applies above 80% loan-to-value and can be removed later. Everything here is subject to lender guidelines and full file review.

What Does “Little Down” Mean on a Conventional Loan?

Anyone who doesn’t qualify for the first-time tier is generally looking at 95% leverage, or 5% down.

Loan-to-value (LTV) is the loan amount divided by the lesser of the sale price or the appraised value. That detail matters. A low appraisal pushes LTV up and can knock a file out of the 97% tier, or raise the cash needed at closing.

The 20%-down rule is a myth. Pricing and available terms vary by lender, borrower profile, property type, and full underwriting review. Lendmire’s conventional loan programs are built on this same agency framework. Lendmire is a mortgage broker, so it arranges these loans through wholesale lenders rather than lending directly.

How Is the Loan Underwritten, Step by Step?

Underwriting runs in a fixed order: pick the program, run credit and automated underwriting, test the debt ratio, document the funds, then appraise the property. Each step can change the outcome of the next. Here is how it plays out across the wholesale programs Lendmire places files with.

Step 1: Pick the pathway. Three paths cover most low-down buyers. Standard 97% requires a first-time buyer. HomeReady requires income at or below 80% of area median income, and it does not require a first-timer. The 97% tier is limited to fixed-rate loans, per Fannie Mae’s 97% LTV FAQs. Adjustable-rate and high-balance loans are excluded. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.

Step 2: Credit and automated findings. The wholesale conventional programs start at a 620 decision score. For manually underwritten adjustable-rate loans, the floor is 640. Most files, though, are governed by the automated underwriting finding. A strong finding can carry a thinner file. A weak one can sink a file with a decent score. Some lenders add their own, higher floors, so the same borrower can get different answers from different lenders.

Step 3: Debt-to-income. Debt-to-income (DTI) compares your monthly debts, including the new mortgage payment, to your monthly gross income. On automated files the total ratio ceiling is 50%. Manually underwritten loans run 36%, or 45% when the file has the reserves and score the Eligibility Matrix asks for. Fannie Mae’s Selling Guide on debt-to-income ratios adds an important wrinkle: if the ratio is recalculated before closing and lands above the limit, the loan can’t be delivered. Taking on a car loan between approval and closing is one of the most common ways to break a file.

Step 4: Funds for the down payment and closing costs. On a one-unit principal residence above 80% LTV, the Selling Guide’s gift rules require no minimum contribution from the borrower’s own funds. The whole transaction can be funded by a gift. The donor signs a gift letter stating the amount and that no repayment is expected, and the lender verifies the donor has the money.

Step 5: Homebuyer education. When every occupying borrower is a first-time buyer and the standard loan goes above 95% LTV, one borrower completes a homeownership course. HomeReady asks for the same on any purchase where all borrowers are first-timers. Fannie Mae’s HomeView course can satisfy it. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.

Step 6: Appraisal and final review. The appraisal sets the value that LTV is measured against. After that, the lender re-verifies credit and debts before closing. Quiet is good. New credit inquiries and new accounts are not.

Requirements at a Glance

Which Low-Down Program Fits Your File?

The right program depends on income and first-time status, not on which one sounds friendlier. A file can qualify for more than one, and the choice often comes down to income and the mortgage insurance structure.

HomeReady has an advantage worth knowing about. Rental and boarder income can count, and non-borrower household income can act as a compensating factor. Per the Fannie Mae HomeReady page, the home must be a principal residence, and income limits are built into automated underwriting. Fannie Mae also offers an income lookup tool for checking a specific address.

Here’s the tradeoff. If your income sits near the 80% line, HomeReady’s reduced mortgage insurance may be the better fit. If you’re above it, the standard 97% tier or HomeOne is the practical route. And if you’ve owned a home within the last three years, none of the first-time tiers apply. You’re looking at 95% leverage instead.

Where Does the General Rule Break?

The 3%-down rule breaks on property type, loan size, loan structure, and borrower history. Several named edge cases catch buyers off guard.

Multi-unit homes. The 97% tier is for one unit only. Two- to four-unit principal residences go to 95% under the wholesale programs, and gift-funded purchases of those properties require 5% from the borrower’s own funds above 80% LTV. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.

Manufactured homes. Standard manufactured housing is capped at 95% LTV, and a HomeReady manufactured home must be a single unit run through automated underwriting. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.

High-balance loans. The 97% tier excludes high-balance loans, so check that your loan amount stays within the baseline. FHFA publishes the conforming loan limits, and limits are higher in high-cost counties. Look up your own county before you shop.

Second homes and investment property. Occupancy decides leverage. Second homes go to 90% and investment property to 85% on one unit, so a low-down first-time loan is a primary-residence tool only.

Credit events. The agencies set waiting periods: four years from a chapter 7 discharge, seven from a foreclosure, and four from a short sale or deed-in-lieu. Documented extenuating circumstances can shorten them.

Down payment assistance layered on top. Community Seconds and Affordable Seconds can push combined LTV above 97%, up to 105% in the agency programs. Rules on stacking vary by program, so ask before you assume.

How Does Mortgage Insurance Work, and How Does It End?

Mortgage insurance is required on any conventional loan above 80% LTV, and unlike FHA insurance, it comes off. Published typical annual premiums have run from 0.58% to 1.86% of the balance. That is a range, not a quote. Your actual cost depends on your credit and leverage. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.

Two removal paths exist under the Homeowners Protection Act. At 80% of the original value, you can ask to cancel in writing, provided you have a good payment history, no subordinate liens, and no decline in value. At 78%, the servicer must terminate it automatically if you’re current. The CFPB’s PMI guidance lays out the conditions. A common mistake is waiting for 78% when 80% was available.

Servicers can also review removal based on a home’s current, appreciated value, and the rules differ by servicer. That’s a conversation to have with yours, not a promise to plan around.

What Does the Decision Look Like in Practice?

The real decision is how much to put down, and the answer is rarely “the minimum” or “20%.” It’s a tradeoff between cash on hand, monthly cost, and reserves.

Picture a first-time buyer with modest savings and a gift from a parent. Putting 3% down keeps cash in the bank, but it means the largest loan balance and mortgage insurance on top. Putting 5% down trims the balance and often improves the insurance picture, though it drains savings. Neither answer is right in the abstract. A buyer with thin reserves after closing is usually better off keeping the cushion.

Another buyer has solid income but a thin credit file. Here the automated finding matters more than the headline score, and paying down a card before applying can change the finding. That’s worth testing before a purchase contract, not after.

A third buyer carries a car loan near the edge of the ratio ceiling. The tradeoff is blunt: a smaller target price, a larger down payment, or a co-borrower. Non-occupant co-borrowers add income but can lower the allowed ratio on manual files.

What if you don’t qualify yet? Work the list in this order: debts first, then credit utilization, then savings and gift documentation, then program fit. And if the first-time tiers aren’t available, 95% leverage on a standard purchase is still a low-down conventional path. Terms depend on the lender’s guidelines, the property type, the leverage, and a full review of the credit profile.
