The Quick Read: On an investment property, a jumbo loan typically means putting down about 20% to 25%, because no single rule sets the number; each program caps leverage by loan size, credit score, property type, and how well the rent covers the payment. Across the wholesale network Lendmire places files with, most purchases land at 75%-80% loan-to-value (LTV). A bigger down payment helps, but it never overrides credit floors, reserve rules, or property eligibility.
- Purchases typically run 75%-80% LTV, which means 20%-25% down. Select high-leverage programs reach 85% LTV (15% down) with roughly a 700+ score.
- Rate-and-term refinances can reach 85% LTV; cash-out tops out at 75% on standard rentals.
- Reserves run about 6 months of the full monthly payment, stepping up to about 9 months above $1,500,000.
- Credit tiers start at a 620 floor, and most programs want roughly 660 or better.
- Clearing the rent test is a separate hurdle from having enough equity.
All of this is subject to lender guidelines, and none of it is a commitment to lend.

What Makes a Loan Jumbo?
A loan is jumbo when the amount you borrow exceeds the county’s conforming loan limit for that unit count. It is not the purchase price that counts. It is the loan amount after your down payment comes off the price.
That distinction matters for your cash. A larger down payment can pull a loan back under the limit and out of jumbo territory entirely.
“Jumbo” is a size label, not a down payment rule. Nobody publishes a required percentage. Each lender sets its own, which is why you see such a wide spread across programs.
How Much Down Does an Investment Jumbo Need?
Plan on 20% to 25% down for a purchase on most programs in the network. Down payment is simply 100% minus the maximum LTV. The ceiling changes with the type of transaction.
| Transaction | Typical max LTV | Equity or down |
|---|---|---|
| Purchase, standard rental | 75%-80% | 20%-25% |
| Purchase, select high-leverage program | 85% | 15% (700+ score) |
| Rate-and-term refinance | up to 85% | 15% or more |
| Cash-out, standard rental | 75% | 25% or more |
| Cash-out, short-term rental | 70% | 30% or more |
Short-term-rental collateral is treated more conservatively. Purchases on those properties top out at 75% LTV. Lenders typically also want a score of 640 or better and about 12 months of hosting history. Short-term rental rules can vary by city, county, HOA, and property type, so investors should confirm local rules before relying on projected rental income.
On a refinance, your existing equity plays the role of the down payment. Whatever the lender won’t lend, you must already own.
How Underwriting Treats It, Step by Step
Underwriting for a rental jumbo runs through the same sequence on most files. Walking it in order shows where your required down payment really comes from.
1. Loan size sets the category. Price minus down payment gives the loan amount. That amount is compared to the county limit for the unit count.
2. The lender finds the lowest LTV that applies. Several caps overlap: loan-size tier, credit score, rental coverage, property type, and purchase versus cash-out. The tightest cap wins.
3. Leverage steps down as the balance grows. Across the network, larger loan bands carry lower maximum LTVs and higher credit floors. Very large balances can also add appraisal requirements. Standard programs reach up to $3,000,000.
4. Rental coverage is tested. The debt service coverage ratio (DSCR) is monthly rent divided by the full monthly payment: principal, interest, taxes, insurance, and any association dues. That payment is called PITIA. On interest-only loans, the test uses interest, taxes, and insurance.
5. Credit is checked against the tier. A 620 floor exists in parts of the network, most programs want roughly 660, and 700 or higher unlocks the strongest leverage tiers.
6. Documents prove the file. Expect the purchase contract, a market-rent appraisal form (the 1007 for a single-family home, the 1025 for a two-to-four unit property), entity papers if you buy in an LLC, and asset statements. The statements prove your down payment and reserves.
A bigger loan means a bigger payment, and a bigger payment pulls coverage down. That is why the practical down payment is sometimes set by the rent test rather than the stated maximum LTV. If rent is thin, you may need to put down more to make the numbers clear.

Why the Same Loan Can Flip Between Jumbo and Conforming
The county limit is set each year by the Federal Housing Finance Agency. The current baseline for a one-unit property in most of the country is $832,750. The ceiling in high-cost areas is $1,249,125, and limits run higher for two-to-four unit properties.
Take a $1,000,000 purchase in a baseline county. At 25% down, the loan sits under the baseline limit, so it is conforming-size. At 15% down, which only select high-leverage programs allow with roughly a 700+ score, the loan sits above that limit, so it is jumbo. Same house, different category, just from the down payment. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
The limit also doesn’t shrink when prices fall. HousingWire notes that the ceiling rises when home prices rise but does not drop when they decline. A loan that was jumbo last year can be conforming now, and the reverse can happen too.
Does Rental Income Change the Down Payment?
Yes, in how you qualify, though not in how much equity a lender wants. A fully documented jumbo tests your personal income, debts, and traditional personal-income documentation. A DSCR loan qualifies primarily on property-level rental income covering the payment, subject to lender guidelines.
DSCR loans are designed for non-owner-occupied investment properties. Because they are business-purpose investor loans, they are reviewed differently from a standard owner-occupied mortgage. The CFPB’s Truth in Lending manual lists business-purpose credit among the transactions exempt from Regulation Z.
A jumbo can be fully documented and still meet the standard for a qualified mortgage. A DSCR loan is non-QM at any size, meaning it falls outside that standard because it doesn’t test your personal ability to repay.
Buying in an LLC is common for investors, subject to program terms. Entity papers become part of the file.
One distinction trips up many first-timers. A DSCR of 1.00 or more is not the same as positive cash flow. The ratio compares rent to the housing payment only. Repairs, vacancy, management, utilities, and capital expenses sit outside it.
Where the General Rule Breaks
The 20%-25% range holds for plain, well-qualified rentals. These edge cases move it.
- Lower coverage. A coverage ratio of 1.00 is where many select programs start. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted, which usually means more cash down.
- No-ratio files. These are available only through select lenders, generally for borrowers who already own a primary residence.
- Weaker credit. Borrowers near the 620 floor sit in lower leverage tiers than borrowers at 700 or higher.
- Condotels and non-warrantable condos. These carry tighter ceilings, and a purchase cap can differ from a refinance cap on the same property.
- Short-term rentals. Leverage is lower, as the table shows, and the hosting-history requirement applies.
- Very large loans. Above $1,500,000, reserves typically rise, and the highest balances sit in lower-LTV bands.
- Ineligible properties. Manufactured homes (single- and double-wide), log homes, and barndominiums are not offered in these DSCR programs.
Bank-style full-documentation jumbo programs often ask for more equity as the loan grows. They also test personal income. A DSCR file can ask less of your paperwork, but it asks the property to prove itself.
What Else You Need Beyond the Down Payment
Cash to close is more than the down payment. Reserves are a separate cushion held on top of it, never a part of it. Reserves are the months of full housing payments you keep liquid after closing.
Here is the rule of thumb in the network:
- Reserves commonly run about 6 months of PITIA.
- Loans above $1,500,000 typically step up to about 9 months.
- Conservative rate-and-term files at modest leverage under $1,500,000 can see reserves waived.
Reserves vary by lender, leverage, loan size, and transaction type, so treat these as ranges. Add closing costs and any extra appraisal fees on larger balances to your cash plan.
Source of funds matters too. Lenders want to see where the money came from, and gift funds are often restricted on investment purchases. The rules differ by program, so ask before you rely on a gift. Investors who tap existing property for the down payment can read Lendmire’s piece on using home equity for a down payment on an investment property. Tax treatment can depend on how the funds are used and how the property is held; investors should keep clear records and speak with a qualified tax professional before relying on any deduction.
Key Terms Defined
Conforming loan limit: The maximum loan size, set by county and unit count, above which a loan is called jumbo. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
LTV (loan-to-value): The loan amount divided by the property’s value; the down payment is what remains.
DSCR (debt service coverage ratio): Monthly rent divided by the full monthly payment, used to judge whether the property’s income covers its own debt.
PITIA: Principal, interest, taxes, insurance, and any association dues, the full monthly housing payment.
Non-QM: A loan that sits outside the qualified mortgage standard, such as a DSCR loan, because it does not test personal income.
Reserves: Liquid money held after closing, measured in months of payments.
Which Path Fits Your Deal?
Start with the loan size. If a larger down payment drops you under the county limit, a conforming loan may be an option, with its own occupancy and documentation rules. If you stay above it, compare a fully documented jumbo against a DSCR structure.
Choose full documentation when your personal income is strong and clean. Choose DSCR when your traditional personal-income documentation understates your income or you hold many properties. Lendmire’s comparison of a DSCR loan versus a jumbo loan for an investment property walks through that choice in more detail.
Term structure is the last lever. The spine of the network is the 30-year fixed. Select lenders also offer extended terms, interest-only periods, and adjustable structures for investors who want them.
If you are buying or refinancing a rental property and want to see how the numbers work, Lendmire can help you compare DSCR loan options based on the property income, credit profile, leverage, and investor goals. The brokerage arranges DSCR financing through select lenders in its wholesale network across 41 markets, including Washington, D.C.
Frequently Asked Questions
Do I need 20% down on an investment jumbo?
Usually at least that much. Most purchases in the network run 75%-80% LTV, so 20%-25% down is the typical range. Select high-leverage programs reach 85% LTV with roughly a 700+ score. Weaker credit, thin rental coverage, or a larger balance can push the requirement higher.
Do reserves count toward my down payment?
No. Reserves are held on top of the down payment, not inside it. They commonly run about 6 months of PITIA, and about 9 months above $1,500,000, though they vary by lender and loan size.
Can rental income help me qualify?
Yes, on a DSCR loan. The file qualifies primarily on the property’s rent covering the payment, subject to lender guidelines. Your credit and reserves still matter, and rent alone cannot lift leverage past the program cap.
Does buying in an LLC change the down payment?
Not by itself. Entity vesting is allowed subject to program terms, and it adds entity documents to the file. The LTV tiers follow the loan, property, and credit profile.
What if the rent doesn’t cover the payment at 1.00?
Select lenders in the network offer paths below 1.00 with leverage and terms adjusted. Expect to bring more cash or accept a lower LTV. Qualification stays subject to credit approval and property review.
