Twenty percent down. That is the number everyone quotes, the number every blog post defaults to, and the number that quietly costs investors more deals than bad markets do. Not because 20% is wrong, sometimes it is exactly right, but because treating it as a default means you never actually ran the math on what that capital could be doing instead.
The down payment is not the cost of the deal
The most common mistake first-time investors make is treating the down payment as the total entry cost. It is not. The down payment is one line item on a larger invoice, and the other lines are what catch people off guard at the closing table.
Take the calculator's defaults: a $350,000 property with 25% down at 7.25%. The down payment is $87,500. That is the number in your head. Here is the number that actually has to be in your bank account:
Closing costs at roughly 3% add $10,500. Then your lender wants to see 6 months of PITI sitting in your account after closing, not before, after. On a $1,790 monthly payment, that is another $10,740 that cannot go toward the down payment. The deal costs $109,000 in liquid capital, not $87,500. Plan for the real number or risk having a deal fall apart three days before closing.
Down payment by loan type
The 20%-to-25% range gets repeated so often that investors forget how wide the actual spectrum is. An FHA house hack in a market like Columbus or San Antonio can get you in for 3.5%. A VA loan gets you in for zero. Meanwhile, a conventional investment loan on a fourplex wants 25% and is not negotiating.
| Loan type | Property | Min. down |
|---|---|---|
| Conventional (investment) | Single-family rental | 15% to 25% |
| Conventional (investment) | 2-4 unit | 25% |
| DSCR / non-QM | 1-4 unit investment | 20% to 25% |
| FHA (house hack) | 2-4 unit, owner-occupied | 3.5% |
| VA (house hack) | 1-4 unit, owner-occupied | 0% |
The loan type you choose is itself a down payment strategy. Investors who house-hack a duplex in Indianapolis with an FHA loan at 3.5% are not being cheap. They are being capital-efficient. They keep $75,000 more liquid than the investor who puts 25% down on a single-family rental in the same market. That $75,000 is the next deal.
The leverage paradox
Here is the part that makes the 20%-down crowd uncomfortable: less down payment produces higher returns. And here is the part that makes the minimum-down crowd uncomfortable: less down payment also produces higher risk. Both things are true at the same time.
| Down % | Down amt | Cash to close | Monthly pmt | Cash-on-cash* |
|---|---|---|---|---|
| 20% | $70,000 | $80,500 | $1,909 | ~8.6% |
| 25% | $87,500 | $98,000 | $1,790 | ~6.1% |
| 30% | $105,000 | $115,500 | $1,671 | ~5.0% |
*Assumes $2,400/mo gross rent, 40% operating expense ratio on a $350,000 property at 7.25%.
At 20% down, you earn 8.6% cash-on-cash. At 30%, it drops to 5.0%. Your monthly cash flow is actually higher at 30%, about $238 more per month, but you put $35,000 more into the deal to get it. That extra $35,000 is earning roughly 8.2% on its own, which is fine, but it is lower than what the first dollars earned. Each additional dollar of down payment works less hard than the last.
This is not an argument for minimum down payment. It is an argument for being intentional about it. The investor putting 30% down on a rental in Tampa and the one putting 20% down in Memphis are both making rational choices; they are just optimizing for different things.
The velocity of money
There is a concept that separates investors who build portfolios from investors who own a property. It is called velocity of money, and it changes how you think about every down payment decision.
Say you have $175,000 to invest. You can put $87,500 into one deal at 25% down, a solid, well-capitalized purchase with comfortable cash flow. Or you can put $87,500 into two deals at roughly 20% down each, accepting thinner margins on each property but doubling your exposure.
2 deals at 20% down: $87,500 x 2 invested, ~$350/mo each = $700/mo total
The two-deal scenario produces more total cash flow, more appreciation exposure, and more depreciation write-offs. It also produces more risk, more management headaches, and thinner margins on each property. Neither answer is wrong. But if you never consider the two-deal version, you are leaving a strategic option on the table.
Investors in high-yield Midwest markets like Cleveland, Kansas City, or Birmingham often lean into velocity because the price-to-rent ratios support thinner margins. Investors in appreciation-driven coastal markets like San Diego or Austin tend to capitalize each deal more heavily because the cash flow margins are already razor-thin.
Closing costs: the forgotten line item
Everyone budgets for the down payment. Almost nobody budgets accurately for closing costs. Then they scramble two weeks before closing when the preliminary settlement statement shows up $14,000 higher than expected.
- Conventional investment loans: 2% to 3%. Lender fees, appraisal, title insurance, escrow, prepaid taxes and insurance. A $350,000 deal runs roughly $7,000 to $10,500.
- DSCR and non-QM loans: 3% to 5%. Same fees plus 1 to 2 origination points. On a $262,500 loan (25% down on $350,000), one point is $2,625 and two points is $5,250. That alone pushes closing costs into the $12,000 to $17,500 range. This is the hidden cost of DSCR flexibility.
Adjust the closing cost percentage in the calculator above and watch how it changes the total cash to close. The difference between 2% and 4% on a $350,000 property is $7,000, real money that you need liquid and that you do not get back.
Cash reserves: the capital your lender will not let you spend
Reserves are the cost that does not feel like a cost because you technically still have the money. But you cannot touch it. Your lender wants to see 3 to 12 months of PITI in your bank account after the down payment and closing costs leave it. After. Not before.
On a $1,790 monthly payment, 6 months of reserves is $10,740. On a portfolio with five properties, each with a $1,500 average payment, reserve requirements can run $45,000 to $90,000 across the portfolio. This is the constraint that slows scaling more than anything else: not finding deals, not getting approved, but having enough cash left over after the last deal closed to satisfy the next lender.
Investors who scale efficiently in markets like Indianapolis, Memphis, or Charlotte learn to think of reserves as a portfolio-wide number, not a per-deal number. They keep a single reserve pool that satisfies multiple lenders. Some lenders will even count equity in other properties as partial reserves. Ask, because they will not volunteer it.
PMI: what it costs and why most investors avoid it
Private mortgage insurance kicks in when the down payment is below 20%. On an investment property, PMI adds roughly 0.5% to 1% of the loan balance per year to your payment. It protects the lender. It does nothing for you.
On a $350,000 property with 15% down ($52,500), the loan is $297,500. PMI at 0.75% adds about $186 per month. That $186 comes straight out of cash flow. On a property netting $400 a month before PMI, it cuts your return nearly in half. Most investment loan programs sidestep the issue entirely by requiring 20% or more as a minimum. If you have access to a 15%-down conventional investment loan, model the deal with PMI included. Sometimes the lower entry cost still wins. Often it does not.
Two strategies for two kinds of investors
Down payment strategy is ultimately a portfolio question, not a property question. The right number depends on where you are in your investing career and what you are optimizing for.
- Optimize for safety. Put 25% or more down, lock in a DSCR above 1.25, and build a thick cash flow cushion. This is the right play when you have a concentrated portfolio, when your day job cannot absorb a cash call, or when you are buying in markets with uncertain rent growth. A landlord in Jacksonville or Phoenix with three properties and no W-2 fallback should probably capitalize each deal heavily. Slower scaling, but each property stands on its own.
- Optimize for velocity. Put the minimum down, accept thinner margins, and deploy the saved capital into the next deal. This suits investors early in their build, those with stable day-job income, tolerance for tighter months, and a clear plan for each dollar not going into the current deal. An investor in their 30s with a strong W-2 buying rentals in Cleveland or Memphis can afford to run leaner on each property because their personal income backstops the portfolio.
Most successful investors do not pick one strategy forever. They start lean, scale fast, and then shift toward heavier capitalization as the portfolio grows and there is more to protect. The down payment on property number two does not have to match property number twelve.
Frequently asked questions
How much down payment do I need for an investment property?
It depends on the loan. Conventional investment loans on a single-family rental run 15% to 25% down. Two- to four-unit properties typically require 25%. DSCR loans start at 20% to 25%, and FHA house-hack loans go as low as 3.5% if you live in one unit. But the down payment is not the number that matters: add closing costs and reserves and you are looking at 30% to 40% more than the down payment alone.
Is it better to put 20% or 25% down on a rental property?
That depends on whether you are optimizing for cash flow or velocity. At 20% down, you keep $17,500 more liquid on a $350,000 property. That capital earns nothing sitting in the deal. At 25%, your monthly payment drops by about $120 and your DSCR improves, which means better loan pricing. Run both in the calculator. Then ask yourself whether that $17,500 gets you into another deal or just sits in a savings account. If it sits, put 25% down.
What closing costs should I expect on an investment property?
Budget 2% to 5% of the purchase price. On a $350,000 property, that is $7,000 to $17,500 covering lender origination fees, appraisal, title insurance, escrow, and prepaid taxes and insurance. DSCR and non-QM loans sit at the higher end because of 1 to 2 origination points. This is the cost everyone forgets when they say they have enough for 20% down: they usually mean 20% of the purchase price, not 20% plus another $12,000.
Do I need cash reserves on top of the down payment and closing costs?
Yes, and this is where deals die. Most lenders want 3 to 12 months of PITIA sitting in your account after closing. Not before. After. On a $1,790 monthly payment, 6 months of reserves is $10,740 that cannot go toward the down payment. Your lender will verify it. A $350,000 deal at 25% down does not cost $87,500. It costs roughly $109,000 when you add closing costs and reserves. Plan for the real number.
What is PMI and does it apply to investment properties?
Private mortgage insurance kicks in when your down payment is below 20%, adding roughly 0.5% to 1% of the loan balance per year to your payment. On a $297,500 loan, that is about $186 per month that goes straight to the insurer and does nothing for you. Most investment loan programs sidestep PMI by requiring 20% or more as a minimum. If you have access to a 15%-down conventional investment loan, model the PMI cost before you celebrate the lower entry point, because it often erases the cash flow advantage.
How does the down payment affect my cash-on-cash return?
Leverage amplifies returns when a deal is profitable. On a $350,000 property netting $500 a month in cash flow, 20% down ($70,000 plus closing costs) produces roughly an 8.6% cash-on-cash return. Move to 25% down ($87,500 plus closing costs) and it drops to about 6.1%, even though your monthly cash flow is higher. You put $17,500 more into the deal to earn an extra $119 a month. That extra capital earns about 8.2% on its own, which is decent but lower than the blended return at 20%. The math always favors less down, until the deal goes sideways.
Can I use a HELOC or gift funds for the down payment?
For conventional investment loans, lenders generally require the down payment to come from your own funds, not gifts. A HELOC on another property works because it is your equity, though it adds debt to your balance sheet and affects your DTI. FHA owner-occupied house-hack loans do allow gift funds. The investors who scale fastest tend to recycle equity through HELOCs rather than saving from income. It is a strategy worth understanding, but confirm sourcing requirements with your specific lender before you commit.
What is the minimum down payment for an FHA house hack?
FHA allows 3.5% down on a 2- to 4-unit property if you live in one unit for at least a year. On a $350,000 duplex, that is $12,250 down, less than some people spend on a used car. It is the cheapest way to start building a rental portfolio, and it is how a lot of successful investors got their first deal in expensive markets like Denver or Portland. The trade-off: FHA mortgage insurance stays for the life of the loan, and you actually have to live there.
