The Quick Read: Yes, it can work, but only when the DSCR program accepts documented borrowed funds, the cash reaches your own bank account with a clean paper trail from draw to deposit, and the rent still covers the property payment without help from you. A securities line is a loan against your portfolio, so you borrow the cash instead of selling shares. Shares sitting untouched in a brokerage account are not cash to close.
- Many programs in the wholesale network accept documented borrowed funds. Some cap how much of the down payment can be borrowed.
- Borrowed money often cannot be used to meet reserve requirements.
- Rent still has to cover the property payment, and the line’s own monthly payment comes out of your pocket.
- A falling portfolio can force a sale, so ask the lender before you draw.
Do Unsold Stocks Count as a Down Payment?
No. A lender needs money that can be traced into a bank account and then to the closing table. Shares in a brokerage account are an asset, not cash.

Short-term rental figures are estimates only and vary significantly by season, property type, management approach, and local short-term-rental rules — confirm local regulations before relying on them. Qualifying income for short-term rentals varies by program — some use appraisal market rent, others use documented STR history or projections — and is confirmed in underwriting. Not a Loan Estimate, approval, or commitment to lend. Program availability and eligibility are subject to lender guidelines, credit approval, property review, and underwriting.
That distinction trips up many first-time investors. You may hold a large portfolio and still have no way to show it as cash to close. You have two routes: sell the shares or borrow against them.
Unsold shares can sometimes help in a different way. On some files, a portion of the portfolio can count toward reserves after closing. Reserves are the cushion the lender wants left over, not the money used to buy.
Key Terms Defined
Securities-backed line of credit (SBLOC): A revolving loan secured by stocks, bonds, or funds in a taxable account you pledge to the lender.
Margin loan: A loan from your brokerage secured by the securities in that same brokerage account.
Cash to close: The money you bring to closing for the down payment and closing costs.
Reserves: Liquid funds left after closing, usually counted in months of the property’s full payment.
PITIA: Principal, interest, taxes, insurance, and any association dues. It is the full monthly housing payment on the property.
DSCR (debt service coverage ratio): Monthly rent divided by PITIA. A result of 1.00 means rent equals the payment.
Maintenance call: A demand to add collateral or repay part of the line when the pledged portfolio falls in value.
Seasoning (of funds): The time borrowed or deposited money sits in your account so it shows up clearly on statements.
Will a DSCR Lender Accept Borrowed Funds?
It depends on the program, and that is the honest answer. Across the wholesale network where Lendmire places files, many programs accept documented borrowed funds. Others do not, and the ones that do often add limits.
Here is what typically varies from program to program:
| Question | What programs differ on |
|---|---|
| Are borrowed funds allowed at all? | Yes, no, or only with conditions |
| Is the borrowed share capped? | Some cap it, some do not |
| Can borrowed money count as reserves? | Often no |
| Is a waiting period required before use? | Program-specific |
| How is the loan’s payment treated? | Program-specific |
The reasoning behind the caution is simple. A lender wants to know the down payment is your equity, not another debt stacked on the purchase. A line secured by your own portfolio is easier to defend than an unsecured loan. Even so, the program has the final word.
DSCR underwriting also does not rely on your personal income ratios. The loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. Source-of-funds review still applies, though. The property is tested on rent, and your money is tested on where it came from.
Down Payment, Closing Costs, and Reserves Are Three Different Pots
Borrowed money may be accepted in one pot and refused in another. Treat them separately before you draw anything.
| Pot | Borrowed securities-line cash | Unsold shares |
|---|---|---|
| Down payment | Program-specific; many accept it | Not cash to close |
| Closing costs | Program-specific | Not cash to close |
| Reserves | Often not accepted | May count on some files |
Leverage sets how big the first pot is. On an investment-property purchase, most files land at 75%–80% LTV, which means 20%–25% down. Select high-leverage programs reach 85% LTV, or 15% down, with roughly a 700+ credit score. LTV (loan-to-value) is the loan balance divided by the property’s value.
A smaller down payment means a smaller draw on the line. That lowers your risk if the market turns. It is one reason to take the highest leverage you can comfortably carry, not the lowest.
Reserves usually run about six months of PITIA. Conservative rate-and-term files at modest leverage under $1,500,000 can see reserves waived. Loans above that size typically step up to about nine months. Lender, leverage, loan size, and transaction type all move the number.
How a Securities Line Puts Cash in Your Hands
An SBLOC is a revolving line of credit secured by the securities in your accounts, according to the SEC’s Office of Investor Education and Advocacy. You keep the portfolio. Payments are monthly and interest-only, and you can repay principal whenever you choose and borrow again later.
One feature matters for real estate buyers. FINRA describes these lines as non-purpose loans, which means the proceeds cannot be used to buy or trade securities. Buying a rental house is outside that restriction. Schwab’s explainer adds two practical points. The pledged account is a taxable, non-retirement account, and the funds cannot be deposited back into a brokerage account.
That second point shapes the steps. Here is the sequence that tends to work:
1. Ask the DSCR lender first. Confirm whether borrowed funds are allowed, whether the borrowed share is capped, and whether any of it can count toward reserves.
2. Open the line. Set it up at your bank or brokerage and pledge a taxable account. Do this before you need the cash.
3. Draw and move the money to your own bank account. Keep it in your name so the trail is short.
4. Let the funds show on a statement. Some programs want the money to appear on a statement before they will count it.
5. Underwrite the property on rent. For a single-family rental, the appraiser typically supplies a 1007 rent schedule, and the lender compares that rent to PITIA.
6. Wire the cash to closing from your account.
Step one is the gate. Drawing before you ask is the most expensive mistake in this strategy, because a draw cannot be undone in the lender’s eyes.
Documents a Lender Will Want to See
Expect a full paper trail. The details vary by program, but the usual file looks like this:
- The line agreement showing the lender, the limit, and the payment terms
- Statements from the line showing the draw
- Bank statements showing the deposit into your account
- Statements for the pledged account
- A credit report that reflects any new liability
A new liability can matter even though DSCR does not use personal debt-to-income. The lender still wants to understand your obligations, and the line adds an interest-only payment that you carry on top of the mortgage.
A Worked Example: Two Payments, One Property
Run the numbers on a single-family rental purchased at 75% LTV, so the buyer puts 25% down. Assume the buyer funds that 25% by drawing on a securities line. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
Suppose the property’s monthly rent comes in at roughly 1.25x PITIA. That is a modeled assumption, not a market figure. On paper, the rent covers the full property payment with some cushion, and many programs would view that coverage favorably, subject to lender guidelines.
Now add the second payment. The line’s interest-only payment belongs to you, not to the property. The rent covers the mortgage payment at 1.25x, but it covers none of the line payment. Whatever you owe on the line comes from your other income or savings.
Two ideas follow. First, a DSCR above 1.00 is not the same as positive cash flow. The ratio compares rent to PITIA only. Repairs, vacancy, management, utilities, and capital expenses sit outside it. Second, the real cushion on this deal is thinner than the ratio suggests, because the draw added a payment the ratio never sees.
Now try the same property with a select high-leverage program at 85% LTV and a 700+ score. The down payment is 15%, so the draw is smaller and the line’s payment shrinks with it. Leverage trades one risk for another, and the right choice depends on how much monthly pressure you can absorb. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
Coverage itself has several paths. A 1.00 ratio is where many select programs start. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. A bigger down payment can lift the ratio, but it never erases the leverage caps, credit floors, reserve rules, or property eligibility. The strongest files clear both tests: enough equity and enough rental coverage.
DSCR vs. conventional financing
There are two common ways to finance an investment property, and they qualify you differently — here’s how investors weigh them.
Why investors choose it
- Qualifies on the property’s rental income — no personal tax returns, W-2s, or pay stubs needed to document income.
- No personal debt-to-income ceiling to clear, so existing mortgages and obligations don’t cap your borrowing the same way.
- Can be closed in an LLC, keeping the property inside a business entity.
- Built for scaling — not held to the limit on number of financed properties that conventional financing applies.
- Underwriting centers on the deal: generally qualifies when the rent covers the payment, a 1.00x coverage ratio being a common baseline (confirmed in underwriting).
- Designed specifically for investment property, including long-term and, where the program allows, short-term rentals.
Where it’s strong
- Often the lowest ongoing financing cost for a buyer who fully qualifies on personal income — a fit for a first property or a cost-first purchase.
Trade-offs for investors
- Requires full personal income documentation and must fit within a debt-to-income limit — salary, existing debts, and other mortgages all count.
- Typically held in your personal name rather than a business entity.
- Caps how many financed properties you can carry, which can become a ceiling as a portfolio grows.
- Evaluates you as a borrower as much as the property, which usually means more paperwork.
How investors usually choose: a first or single property often optimizes for the lowest financing cost; portfolio builders often optimize for leverage, vesting in an LLC, and scaling past conventional caps. The right answer depends on your goals, the property, and current guidelines — both paths run through select lenders in Lendmire’s wholesale network, with eligibility and terms confirmed in underwriting.
What Happens If the Portfolio Drops?
The risk is real, and it is the part most investors underweight. The regulators’ investor alert warns that you may be forced to sell securities if the collateral value falls, and that the firm can decide which securities to sell. A maintenance call typically gives two or three days to post more collateral or repay part of the line. If you cannot meet it, the firm can sell your securities.
Here is how the risk plays out around a purchase:
| Risk | Trigger | Practical response |
|---|---|---|
| Maintenance call | Portfolio value falls | Keep the draw small; hold spare liquidity |
| Concentration | One stock makes up most of the pledge | Diversify before borrowing |
| Collateral change | Firm stops accepting a holding | Ask which holdings qualify |
| Payment stacking | Line interest plus property costs | Stress-test with the line payment included |
| Reserve shortfall | Borrowed cash cannot count as reserves | Hold separate liquid funds |
A drop between draw and closing is the uncomfortable case. If the cash has already moved to your bank account, the purchase can proceed. If a call forces a sale afterward, you may lose both the position and the cushion you counted on. Size the draw so a sharp decline does not threaten your other plans.
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.
Concentrated portfolios deserve extra caution. A portfolio dominated by one company can fall sharply on a single piece of news. That is a weak pledge for any lender, and a weak base for a down payment.
Is This Better Than a Margin Loan?
Usually yes, for this purpose. A margin loan is made by your brokerage and secured by the securities in the same account. The SEC’s margin bulletin warns that a brokerage can sell your securities without notifying you first when a margin call goes unmet. That exposure to forced selling is why many investors prefer a bank-issued securities line.
An SBLOC is also not the only way to raise cash. Compare the options side by side:
| Option | Main tradeoff | Fit with a DSCR file |
|---|---|---|
| Securities line | Forced-sale risk, extra payment | Program-specific; many accept it |
| Margin loan | Broker can sell without notice | Program-specific; more exposed |
| Cash-out on an existing rental | Reduces equity in that property | Up to about 75% LTV; about 6 months seasoning |
| Selling shares | Gives up market exposure | Plain cash with a clean trail |
The cash-out route has its own logic. Lendmire’s piece Can a Family Office Use DSCR Cash-Out Proceeds as a Down Payment? covers how the proceeds from one rental can fund the next purchase. It suits investors who already own a rental with built-up equity.
There is no single best option here. The stronger play depends on how concentrated your portfolio is, how much you want to stay invested, and whether you hold a rental with usable equity. An investor with a diversified portfolio and modest draw needs often does fine with a line. An investor with one big stock position may be better served selling part of it.
Single-Family Details and the Entity Question
A single-family rental has a simple income story. The appraiser’s rent schedule supports the rent figure, and the lender compares it to PITIA. Borrowed down-payment funds do not change that test.
What they can change is the file’s tone. A lender that sees heavy borrowing, thin reserves, and low coverage may adjust leverage or terms. A lender that sees real equity, fair coverage, and healthy reserves tends to be more comfortable. Credit matters too. A 620 floor exists in parts of the network, most programs want around 660, and 700+ unlocks the strongest leverage tiers. Loan sizes run up to $3,000,000 on standard programs (smaller balances available through select lenders), and above $2,500,000 the network generally holds to 30-year fixed structures.
Property type matters as well. DSCR Investor Loans through the network is not offered on manufactured homes, log homes, or barndominiums.
Then there is the entity question. Say you plan to buy through an LLC but the securities line is in your personal name. Some programs lend to LLC borrowers, depending on program guidelines, and the lender will want to see how the funds move from you to the entity. A clean path is a draw into your personal account, then a documented transfer. Ask about this before you draw, since a mismatch between borrower, title, and source of funds can slow a file down.
Questions to Ask Before You Draw
Take this list to your broker or lender first:
- Does this program accept borrowed funds for the down payment?
- Is the borrowed share capped?
- Can any borrowed money count toward reserves?
- Do the funds need to sit on a statement before closing?
- How does the program treat the line’s monthly payment?
- Can pledged securities count as reserves after closing?
- If the borrower is an LLC, how should the funds move?
Write down the answers. Programs change, and every file is underwritten individually. The complete DSCR loans guide walks through how coverage, leverage, and reserves fit together.

Frequently Asked Questions
Can I use a margin loan for a DSCR down payment?
It depends on the program, and it carries more risk than a bank-issued line. A margin loan is secured by the securities in your brokerage account, and the brokerage can sell them without notifying you if a call goes unmet. Some programs may accept documented borrowed funds from this source, but ask before you draw. Many investors find the forced-sale exposure a reason to choose a different route.
Can I pledge a retirement account for the line?
Usually not. Brokerage explainers note that the pledged account is a taxable, non-retirement account, so an IRA or 401(k) generally does not qualify as collateral. If your wealth sits mostly in retirement accounts, a securities line is likely the wrong tool. A different down-payment source would serve you better.
Does the line’s payment affect my DSCR?
Not directly. The DSCR compares the property’s rent to its own PITIA, and the line’s payment is not part of that ratio. The payment still comes out of your pocket, though, and some programs review it as part of your overall obligations. A strong ratio on the property does not make the extra payment disappear.
Can my LLC borrow against my stocks?
Usually the line is in your personal name because you own the securities. Some programs lend to LLC borrowers, depending on program guidelines. The common approach is to draw into your own account and then document the transfer to the entity. Confirm the path with the lender first.
What if my stocks drop before closing?
If the cash is already in your account, the purchase can usually continue. The danger is a maintenance call, which can force a sale and shrink the funds you counted on, including any reserves. A smaller draw, spare liquidity, and a diversified pledge all reduce the odds of that outcome.
