How Much a 1-4 Unit Rental Investor Puts Down on a Conventional Loan

The Quick Read: On a conventional purchase of a rental you won’t live in, the minimum down payment is typically 15% on a one-unit property and 25% on a two-, three- or four-unit property. Those numbers are simply 100% minus the maximum loan-to-value ratio the agencies allow. Owner-occupied buyers can go far lower on the same building, so occupancy decides the number. Everything below is subject to lender guidelines and full file review.

What Does “Putting Down” Actually Mean Here?

The down payment is the part of the price you pay from your own money. The lender finances the rest. Lenders express that split as loan-to-value, or LTV: the loan balance divided by the property’s value.

An 85% LTV means you borrow 85% and pay 15%. A 75% LTV means you pay 25%. That is the whole conversion, and it is why the table below lists both numbers. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.

The last row is the one that trips people up. It is a different loan, built for a buyer who lives in the building.

Why Do Rental Buyers Put Down More Than Homeowners?

Lenders price risk, and a rental carries more of it. An owner-occupant protects the roof over their own head. A landlord can walk away from a property that stops paying for itself.

So the agencies cap how much of the price a rental buyer can borrow. Fannie Mae’s Eligibility Matrix caps an investment-property purchase at 85% for one unit and 75% for two to four units. Freddie Mac’s Seller/Servicer Guide also lists 75% for a two- to four-unit investment property.

That ceiling explains the gap between one unit and two. Buyers who read “4-unit properties qualify for 5% down” online usually missed the word “owner-occupied.”

Picture the same building at the same price, with only occupancy changed:

• Buy it to live in one unit: up to 95% LTV on two to four units, about 5% down.
• Buy it purely as a rental: 75% LTV, about 25% down. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.

That is a gap of about 20 points of the purchase price, from occupancy alone. Specifics remain subject to lender guidelines and a full review of property, leverage, and credit.

How Is a Rental Purchase Underwritten, Step by Step?

Underwriting means the lender verifies your finances against the rules. For a rental purchase, the sequence looks like this.

1. Occupancy is set. The loan is labeled investment because you will own the property without living in it. That label carries into pricing.

2. The file runs through automated underwriting. The agencies’ leverage caps assume an automated approval. For two- to four-unit rentals, manual underwriting is generally not an option.

3. The appraisal includes a market rent schedule. The appraiser documents what each unit should rent for. The lender wants that figure on file even if you never use it to qualify.

4. Rent is weighed in your income, partially. Fannie Mae’s announcement on rental income ties full use of rental income to having a primary housing expense and a track record managing property. If you have never been a landlord, rent usually only offsets the property’s own payment. It does not raise your qualifying income. Even where rent counts, only a portion does, because the rules assume vacancy and upkeep.

5. Credit and debt ratios are checked. Across the wholesale conventional programs we place files with, the floor is a 620 decision score. The automated finding governs most files, with a total debt-to-income ceiling of 50%. A higher score and lower ratios give the file more room.

6. Reserves and cash to close are verified. More on this below, because it is where files stall.

Mortgage insurance rules apply when leverage goes above 80%. How that works on a one-unit rental at 85% depends on the lender and the file, so ask for it in writing rather than assuming. Mortgage insurance is a policy that protects the lender if you stop paying, and the borrower pays the premium.

What Changes the Number?

The 15% and 25% figures are floors, not promises. Several things can push the real number higher.

Transaction type. A purchase is one case. A limited cash-out refinance of a rental, where you take out little beyond closing costs, follows its own cap. A cash-out refinance on a rental sits at 75% LTV on two- to four-unit properties. The loan being paid off must be at least 12 months old, and you must have been on title for 6 months, with narrow exceptions. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.

Lender overlays. An overlay is a lender’s own rule layered on the agency minimum. Some lenders set a higher credit floor or lower leverage on rentals. This is why you will see different numbers on different websites, and why a pre-approval matters more than a blog headline.

Credit and ratios. A thin credit score or heavy debt can make a file need more cash down or a lower price, even when the agency cap would allow more.

Number of financed properties. Owning several financed properties adds reserve requirements. The agencies tighten the file as your portfolio grows. The details change over time, so your loan officer should pull the current rules rather than rely on a rule of thumb. Terms depend on the lender’s guidelines, the property type, the leverage, and a full review of the credit profile.

What Does the Cash Picture Look Like for a Duplex, Triplex and Fourplex?

The cash you bring is more than the down payment. Closing costs come first, then reserves, which are months of housing payments you must hold in the bank after closing. These examples use percentages only, because dollars depend on the price and the lender.

Duplex at 75% LTV. Down payment: 25% of price. Closing costs: a further share of price. Reserves: several months of the full housing payment, held after closing. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.

Triplex at 75% LTV. Down payment: 25% of price. The higher price of a three-unit building means a larger dollar down payment, and the bigger payment makes the reserves larger too. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.

Fourplex at 75% LTV. Down payment: 25% of price. Reserves scale with the payment, so a fourplex asks the most cash of the three at the same percentage. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.

One-unit rental at 85% LTV. Down payment: 15% of price. Lower cash up front, but a single unit has one rent stream. A vacancy covers none of the payment. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.

Funds to close are counted before reserves. Savings you use for the down payment cannot also count as your reserves. A buyer with exactly enough for the down payment and nothing left is short, even if the down payment itself looks fine on paper.

Where Can the Down Payment Come From?

Your own funds are the cleanest source: savings, proceeds from selling another property, or money already in an account for the lender to review. Lenders want a paper trail. A large deposit with no explanation can stall a file because the underwriter must source it.

Seller credits are different on a rental. Fannie Mae’s interested-party contribution rules say seller and other interested-party money cannot fund the down payment, reserves or minimum borrower contribution. Credits on investment properties are capped at a low share of the price, well below owner-occupied levels. An excess credit is treated as a price reduction, and the LTV is recalculated. Your loan officer should confirm the current cap on the live guide.

Whether gift funds are allowed depends on the occupancy. They are far more limited on a rental than on a home you will live in, so ask before counting on them.

Should You Put Down More Than the Minimum?

This is the practical decision. The minimum gets you the building. A larger down payment changes the file.

• A bigger down payment lowers the loan balance. That generally means a smaller monthly obligation and more cushion if a unit sits empty.
• It can improve pricing. Rental loans are priced higher than owner-occupied loans, and the adjustments vary by credit score and leverage. More equity usually helps. Your Loan Estimate will show the actual terms.
• It drains liquidity. Cash you put into the building is cash you cannot use for repairs, vacancies or the next purchase.
• It can protect against a surprise. If your appraisal comes in low or the LTV lands barely over a cap, extra cash keeps the deal alive.

The stronger play for a first rental is often a down payment that keeps several months of spare cash in the bank. A thin cushion on a four-unit building is a common way a good deal turns stressful.

Where Does the General Rule Break?

Several edge cases change the answer. Know them before you submit an application.

You will live in one unit. The loan becomes an owner-occupied purchase, with leverage that can go well above the rental caps. You must truly occupy a unit. Lendmire’s article How Much Down Payment a Conventional 2-4 Unit Loan Needs covers that path.

A two-unit “second home.” Second homes are one-unit properties. A two-unit property used as a second home is treated as an investment property, so the investor limits apply.

Second-home rent. A second-home loan can have rental income, but that income cannot be used to qualify.

Accessory dwelling unit income. The rule that lets ADU income help you qualify applies only to a one-unit principal residence. It does not apply to rental loans.

Misstating occupancy. Calling a rental your primary home to get a lower down payment is misrepresentation. Fannie Mae’s quality-control bulletin names it as a risk area exactly because the better terms invite the temptation. Do not do it.

Moving in later, or moving out. Buying as an investor and later occupying a unit does not retroactively lower your down payment. If you plan to live there, say so at application. Occupancy is declared at closing and is part of the loan.

What Is the Process From Here?

Start by deciding what the building is for. A rental purchase and an owner-occupied purchase are different loans. Then add up total cash: down payment, closing costs and reserves. Compare that against your savings before you make an offer.

Next, ask a loan officer to run the file through automated underwriting with the property type and units you are considering. That shows how your credit and ratios affect the cash you need. The Loan Estimate then shows the actual terms and costs. If you are comparing programs, Lendmire’s conventional loan programs page lays out the options.

Key Terms Defined

Loan-to-value (LTV): the loan balance divided by the property’s value, expressed as a percentage.

Investment property: a home you own but do not occupy as your residence. Lenders classify it by how you will use it, not by what it looks like.

Overlay: a lender’s own rule added on top of the agency minimum, such as a higher credit floor.

Reserves: months of housing payments you must still hold in the bank after closing.

Interested-party contribution: money from the seller or another party with a stake in the sale, such as a seller credit toward your closing costs.
