The Quick Read: A founder borrows against a brokerage account with a securities-backed line of credit, uses the draw to fund a large purchase, then replaces that line with a permanent super jumbo mortgage that pays it off at closing and releases the pledged portfolio. The sequence works only if the permanent lender has reviewed the file before the first draw and the portfolio holds its value until closing.
- The line is secured by securities, so the house carries no lien until the permanent loan is in place.
- The takeout lender qualifies the founder on documented deposits, assets, or property cash flow instead of traditional personal-income documentation, through select wholesale programs, subject to full underwriting.
- Leverage on the takeout steps down as the loan grows, and every loan above $4,000,000 is reviewed case by case before submission.
- The biggest risk is a collateral call while the permanent loan is still in underwriting.
- One portfolio cannot serve as collateral, down payment, and reserves all at once.
Why Would a Founder Bridge Instead of Selling Shares?
A founder bridges because the portfolio is worth more intact than sold. Appreciated stock may carry a large taxable gain, and selling it also ends the upside. A securities-backed line lets the founder borrow against the holdings, keep owning them, and close on the property.
Founders also run into a second problem. Their traditional personal-income documentation often understates what the business actually produces. Depreciation, reinvested profit, and low owner salaries all shrink the income line a conventional lender reads.
A super jumbo bank statement loan reads the deposits instead. That makes the pairing natural: the line supplies the cash on the purchase date, and the bank statement loan supplies the long-term financing. Brokers who place these files across a wholesale network see this sequence most often when a liquidity event has just happened, or is about to.
Key Terms Defined
SBLOC: A securities-backed line of credit is a revolving line secured by stocks, bonds, or funds in your investment account. Payments are interest-only, and you can borrow again after you repay.
Non-purpose loan: A loan whose proceeds cannot be used to buy or trade securities. Almost any other use is allowed.
Takeout: The permanent mortgage that pays off the temporary financing at closing.
Super jumbo: An industry label for very large mortgages. No agency defines it, so each program draws its own line. Lendmire’s network treats overlays as starting above $3,500,000 on a primary residence and $3,000,000 on a second home or investment property.
Seasoning: How long funds have sat in your account before a lender will treat them as yours.
Maintenance call: A demand from the line’s lender to add collateral or repay because the portfolio’s value fell.
Bank statement loan: A mortgage that is reviewed around 12 or 24 months of deposits instead of tax-return income.
How Does the Takeout Lender Actually Read a Founder?
The takeout lender qualifies a founder through one of three paths: deposits, assets, or, on a rental, property cash flow. Traditional personal-income documentation is not the center of the file. Most programs in the network still weigh credit, debt-to-income, reserves, and the property itself.
Deposits. The lender reviews 12 or 24 consecutive months of personal or business bank statements. The bank portfolio program uses 12. Business statements require at least 25% ownership. Qualifying income is eligible deposits divided by the statement months, after an expense ratio. Fixed ratios are 20% for a service business with no employees, 40% for one to five employees, and 50% for six or more employees or any product business. An accountant-provided ratio or a profit-and-loss method capped at 80% are the alternatives. Transfers from the founder’s own business into a personal account count in full. Statements must be consecutive, because a transaction history never substitutes.
Assets. The asset allowance path divides liquid assets by 36, 60, or 84 months to create qualifying income. It is limited to primary and second homes, at 80% maximum. The assets-only path needs no debt-to-income ratio when U.S. liquid assets equal the loan amount plus closing costs. Retirement accounts count at 70%, or 80% at age 59.5 and older. Business funds, gifts, unvested stock, and cryptocurrency never count. A founder holding mostly unvested equity should read that last sentence twice.
Property cash flow. On an investment property, the loan can qualify primarily on property-level rental income covering the payment, subject to lender guidelines. The complete DSCR loans guide walks through that path.
Across the network, the credit floor is 660 on the portfolio non-QM program up to the super jumbo line and 700 above it. The bank portfolio program keeps a 680 floor at every size. Debt-to-income runs up to 50%. Those are typical ranges through select wholesale programs, subject to full underwriting and not a commitment to lend.
The Sequence, Step by Step
The order matters more than any single step. Founders who draw first and ask questions later are the ones who get surprised.
1. Pre-clear the takeout before touching the line. Ask the broker to review the income path, the property, and the leverage for the loan size you expect. This is the step most often skipped.
2. Confirm the line allows real estate use. The line is non-purpose, so you cannot use proceeds to buy securities. Real estate is a permitted use, and the SEC and FINRA investor alert on securities-backed lines lists it among them.
3. Open the line, ideally before the offer. The lender sets the borrowing limit against the pledged portfolio. FINRA notes that some lenders skip a credit check and set the limit on portfolio value alone, so the portfolio itself drives how much you can borrow.
4. Draw for the down payment or the full purchase. The draw moves to escrow. The property has no lien from this line, and the interest-only payments continue until payoff.
5. Close on the property and apply for the takeout. In practice the takeout application is usually already underway, because step one happened first.
6. Pay off the line at closing and release the pledge. The permanent loan funds, the line balance is paid or settled, and the portfolio is free again.
7. Keep the paper trail. Save brokerage statements, the line agreement, draw records showing money moved to escrow, and the closing statement.
Whether the takeout lender treats line proceeds as a source of funds or as a new debt depends on the program and the structure. Ask before you draw. The answer changes both qualification and leverage.
Purchase Bridge or Cash-Out Bridge?
How the takeout is classified changes the leverage you can use. A line that funds a purchase usually leads to a purchase loan. A line used to pull equity out of a property you already own leads to a cash-out refinance, and cash-out ceilings sit lower.
| Factor | Purchase bridge | Cash-out bridge |
|---|---|---|
| What the line funds | Down payment or full price | Money taken against owned property |
| Takeout classification | Typically a purchase | Typically a cash-out refinance |
| Leverage ceiling | Higher | Lower |
| Main underwriting question | Source of the down payment | Use of proceeds and reserves |
Here is a primary residence example from the network’s ladder. Say the loan lands in the $2,000,000 to $2,500,000 band. Through select wholesale programs, subject to underwriting, purchase and rate-and-term leverage tops out at 80% on a primary residence in that band, and credit of 720 or higher is needed for that top cell. Cash-out in the same band tops out at 70% on a primary residence. A lower score takes a lower leverage cell inside the band.
The bands apply to the loan amount, not the purchase price. Work out price times leverage first, then read the band for that loan.
For larger files the ladder keeps moving. Between $4,000,000 and $5,000,000, a primary residence purchase tops out at 65% through the bank portfolio program, with cash-out at 60%. Both figures are on review and case by case. At $5,000,000 to $6,000,000, purchase drops to 60% and cash-out to 55%, again on review. Above $4,000,000, never treat any figure as a flat promise. The portfolio non-QM program stops at $6,000,000, and the bank portfolio program carries twelve-month-statement files to $30,000,000. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
Second homes and investment property use their own ladders. Read each figure from that occupancy’s column rather than subtracting from the primary figure.
Where the Rule Breaks
The clean sequence has several edge cases, and a few of them can end the deal.
A call during underwriting. The line’s lender can demand more collateral if the portfolio falls. FINRA’s explainer on securities-backed lines says the cure window is typically two or three days. A call that lands mid-underwriting can force sales or force a repayment, and the takeout loses its down payment source. Keep the draw modest against the portfolio and hold cash outside the pledged account to meet a call.
Concentrated stock. A pledge made up of one company’s shares may get a smaller line, or none at all. Lenders often cap borrowing against a single large position or ask for diversification. A founder whose wealth is mostly one stock is the borrower most likely to be limited.
Down payment treated as an asset. On the asset-based path, the lender cannot lean on the down payment as proof you can repay. It must still weigh the payment, other debts, and credit history. The CFPB’s summary of the ability-to-repay rule says lenders must consider income or assets among several factors. A non-QM loan is not an underwriting-free loan.
One pool, three jobs. The pledged portfolio is collateral for the line, and it is also the most likely source of reserves. Reserves run 3 months to $500,000, 6 months to $1,500,000, and 9 months above, plus 2 months per additional financed property to a 12-month maximum. First-time investors need 12 months. Assets pledged to the line and reserve funds should not be the same dollars. Cash-out proceeds also cannot satisfy reserves under the super jumbo overlays.
Pledged-asset mortgage. A different product puts securities up as collateral alongside the property in place of cash down. It stays in place for the life of the loan. An SBLOC bridge is temporary and secured by the securities alone.
A home equity line as the bridge. A HELOC is secured by the home, and the lender may restrict draws if the property’s value falls. That is a different risk from a portfolio call, and it does not apply to a purchase where the home is not yet yours.
Super jumbo overlays. Above $3,500,000 on a primary residence and $3,000,000 on a second home or investment property, programs add a 700 credit floor and a 0x30x24 housing history. They also require 48-month seasoning on any credit event, U.S. citizenship or permanent residency, and no non-occupant co-borrowers. Rural property is excluded, and ten acres is the maximum.
Investment property. Business-purpose investor files are reviewed differently from a standard owner-occupied mortgage.
How Does It Compare to the Alternatives?
| Option | Collateral | Main failure mode |
|---|---|---|
| SBLOC bridge | Securities portfolio | Collateral call |
| Traditional bridge loan | The property | Depends on a sale or takeout |
| HELOC bridge | Equity in the home | Draws can be restricted |
| Selling shares | None | Gain realized, upside gone |
| Jumbo with line-funded down payment | Property plus portfolio | Line stays outstanding |
The tradeoff is honest. Selling shares is simple and removes the call risk, but it ends the exposure and may trigger a tax bill. The line keeps the holdings working while adding market risk during a short window.
The SEC and FINRA alert also warns that market volatility can magnify losses and that forced sales may carry unintended tax consequences. Tax treatment can depend on how the funds are used and how the property is held; borrowers should keep clear records and speak with a qualified tax professional before relying on any deduction.
When Not to Bridge
Skip the bridge if any of these is true:
- Your wealth is mostly one concentrated stock position.
- You have not asked a broker to review the takeout before drawing.
- You have thin liquidity outside the pledged account.
- Your income documentation has not been tested against a bank statement program.
- You are counting unvested equity or cryptocurrency as assets.
If any one of those applies, selling a portion of the holdings or waiting may be the cleaner choice.
A Founder Walkthrough
Picture a founder with appreciated shares in a brokerage account, modest reported salary, and strong business deposits. She wants a primary residence where the loan lands in the $2,000,000 to $2,500,000 band.
She starts by asking a broker to review the file. Her deposits, after the expense ratio for a business with employees, support the qualifying income. Credit sits above 720, so the top purchase cell of 80% on a primary residence is on the table through select wholesale programs, subject to underwriting. Her reserves come from a separate account, not the pledged one.
Only then does she open the line and draw for the down payment. The takeout closes, the line is paid off, and the pledge is released. Nothing about that outcome is promised, but each step removed a specific risk.
The Takeout File: A Document Checklist
- 12 or 24 months of consecutive personal or business bank statements
- Ownership documentation if using business statements (at least 25%)
- Expense ratio support or an accountant letter, if not using a fixed ratio
- Brokerage statements for the pledged account
- The line agreement and draw records showing funds moved to escrow
- Statements for reserve accounts held separately from the pledge
- Purchase contract and property details
Frequently Asked Questions
Will the takeout lender count line proceeds as cash?
It depends on the program and how the transaction is structured. Some programs treat borrowed funds as a source of funds, and others weigh the line as a liability. Ask during pre-clearance, before the first draw.
Can the line be called during closing?
Yes. If the portfolio falls enough, a maintenance call can arrive with a cure window of a few days. Holding cash outside the pledged account is the standard defense.
Is the takeout a purchase or a cash-out?
For a line that funds a purchase, it is typically treated as a purchase. A line used to pull equity from property you already own leads to a cash-out refinance, which carries lower leverage ceilings in every band.
Can retirement accounts be pledged?
Pledging is a question for the line’s lender. For the takeout, retirement accounts count toward the asset paths at 70%, or 80% at age 59.5 and older.
What happens if the takeout slips or fails?
The line stays outstanding and interest continues. Plan for that by keeping a cushion outside the pledged portfolio and by pre-clearing the takeout before you draw.
