Why Rentals Require More Down Than a Home
Owner-occupied buyers can put down as little as 3% to 5% on a primary residence, but investment property is different. Most conventional lenders want 20% to 25% down on a single-family rental, and the requirement can climb for two-to-four unit properties.
The reason is risk. When money gets tight, borrowers tend to protect the home they live in and let an investment property go first. Lenders price that behavior into their rules by demanding more equity up front, which gives them a larger cushion if they ever have to foreclose.
Typical Down Payment Ranges
- Single-family conventional rental: usually 20% to 25% down.
- Two-to-four unit investment property: often 25% or more.
- DSCR and other investor loans: commonly 20% to 30%, priced on the property cash flow.
- House hacking a multi-unit you live in: sometimes as low as 3.5% with an FHA loan.
- The lowest down payments almost always require you to occupy one of the units.
How Down Payment Size Changes Your Returns
Cash-on-Cash Return = Annual Cash Flow / Total Cash Invested
A larger down payment lowers your loan balance, which shrinks the monthly payment and improves monthly cash flow. That feels safer, and it is, but it also ties up more of your capital in a single deal.
A smaller down payment uses more leverage. Your cash-on-cash return can be higher because you control the same asset with less money, but the thinner equity cushion and larger loan payment leave less room for error if rents dip or expenses spike.
Worked Comparison
Imagine a $250,000 rental. At 25% down you invest $62,500 and the loan is $187,500. At 20% down you invest $50,000 and the loan is $200,000. The smaller down payment frees up $12,500 you could use toward a second deal, but it raises your monthly payment and reduces cash flow.
If the property produces $3,000 of annual cash flow at 25% down and $2,400 at 20% down, cash-on-cash is about 4.8% versus 4.8% as well in this simplified case, which shows why you have to run your own numbers. The right choice depends on whether preserving capital or maximizing per-deal cash flow matters more to you.
Finding Your Right Number
- Keep enough cash reserves after closing to cover several months of PITI and a surprise repair.
- Weigh a bigger down payment against the returns you could earn deploying that cash elsewhere.
- Remember that a larger down payment can help a marginal deal clear a lender debt-service test.
- Factor in mortgage insurance, which low down payment loans may require and which eats into cash flow.
- Do not drain your reserves to hit a lower rate, because an undercapitalized rental is a fragile one.
Frequently Asked Questions
Can I buy an investment property with less than 20% down?
Sometimes. Pure investment loans usually want at least 20% to 25%, but if you live in one unit of a two-to-four unit property you can often use an FHA loan with as little as 3.5% down. That house-hacking route is the main way to control a rental with a small down payment.
Does a bigger down payment get me a better interest rate?
Often yes. A larger down payment means a lower loan-to-value ratio, which lenders view as less risky and frequently reward with a better rate. It can also help a tight deal pass a lender debt-service coverage test.
Is a larger down payment always the safer choice?
It lowers your payment and improves cash flow, but it also concentrates more of your capital in one property and leaves fewer reserves. Safety comes from the whole picture, including reserves and cash flow cushion, not just the size of the down payment.
