How Super Jumbo DSCR Source-of-Funds Rules Work for Concentrated-Stock Borrowers

How Super Jumbo DSCR Source-of-Funds Rules Work for Concentrated-Stock Borrowers

The Quick Read: A super jumbo DSCR loan is reviewed for the property on its rent, but the cash to close and the reserves still have to come from your own documented, liquid funds. A large single-stock position is wealth on paper until it is sold or otherwise made countable. Subject to underwriting, the file is judged on the paper trail behind that money, not on your net worth.

  • Rent coverage tests the property. Verified assets test the borrower.
  • Stock can be sold, counted in place, or borrowed against. Each route is treated differently.
  • Reserves on the subject property are typically 6 months of payment, 12 for first-time investors.
  • Cash-out proceeds from the subject property never satisfy reserves above $3,000,000.
  • Borrowed money is the riskiest route to document, and it varies by program.

A borrower who holds a big slice of net worth in one ticker is a common profile on large-balance rental files. The wealth is real, but a lender cannot wire it to a title company. This article walks through how underwriting treats that wealth, step by step, across the programs Lendmire places files with.

Key Terms Defined

Source of funds: the documented origin of the money used for the down payment, closing costs and reserves.

Seasoning: how long money has sat in an account before it is counted, which varies by program.

Reserves: liquid funds held after closing, counted in months of the subject property’s payment.

Liquid asset: money you can use now, such as cash, as opposed to an asset that is only valuable on paper.

Lendable value: the amount a lender will count from an asset after discounting it for risk.

In-kind position: shares left in a brokerage account rather than sold for cash.

Securities-backed line of credit (SBLOC): a loan secured by the securities in your account.

Why Does a DSCR File Skip Income Checks but Not Funds Checks?

DSCR loans qualify primarily on property-level rental income covering the payment, subject to lender guidelines. That is why a concentrated-stock holder, whose income may be lumpy or tied to equity compensation, finds the product attractive. But the property’s rent only answers one question: can this asset carry the debt?

The second question is separate. Where does the down payment come from, and what is left afterward? Personal income documents drop out of the picture. Asset documents do not.

Across the wholesale network, the pattern is consistent. Underwriters want to see the money, trace it, and confirm it belongs to you. At super jumbo size that scrutiny grows, because the amounts are larger and the leverage is lower, which means more of your own cash is at stake.

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.

How Underwriting Treats a Concentrated-Stock File, Step by Step

Underwriting moves in a predictable order. Knowing it lets you prepare the file before you apply.

1. Size the cash need. Add the down payment, closing costs and reserves. On a purchase in the upper bands of the ladder, leverage is lower, so the down payment is larger. Purchase leverage runs 80% to $1,000,000, 75% to $3,000,000, 65% to $4,000,000, and 60% from there on case-by-case review, subject to underwriting.

2. Decide which funds cover which need. Each dollar gets one job. Money used for the down payment cannot also be counted as reserves.

3. Trace each dollar. For stock proceeds, that means the brokerage statement, the sale confirmation, and the bank statement showing the deposit.

4. Check seasoning and large deposits. A fresh deposit rarely ends a file. It usually triggers a sourcing letter and documents. Whether proceeds must sit for a period is program-specific.

5. Net out tax. The amount that lands is not always the amount that counts. More on that below.

6. Count reserves separately. Reserves are 6 months of PITIA on the subject property, or ITIA on an interest-only loan, and 12 months for first-time investors. There are no extra reserves for other financed properties, and a file can carry up to 20 financed properties.

For deeper reserve mechanics, Lendmire’s piece How to Use Business Funds as Reserves on a Super Jumbo Bank Statement Loan covers a related sourcing question.

Sell, Count in Place, or Borrow Against It?

The central decision is how to turn a position into countable funds. Each route trades tax cost, risk and paperwork differently.

Route What the lender sees Documents Common catch
Sell shares New cash in a bank account Sale confirmation, statements Tax bill shrinks usable cash
Count in place Brokerage balance Recent statements Discounted for volatility
Pledge or borrow Cash plus a new debt Line agreement, draw record Callable loan; treatment varies
Staged sale Several deposits over time Each sale and deposit Needs lead time

Route one: sell and wire

Selling is the cleanest path. The proceeds arrive as cash, and the paper trail is easy to follow: brokerage statement, sale record, bank deposit, then a short letter explaining the deposit.

The cost is tax. The IRS explains in Topic 409 that a holding period of more than one year makes a gain long-term, and anything shorter is short-term. A sale at eleven months can be taxed very differently from a sale at thirteen. 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.

Route two: count it in place

Many programs will count a brokerage balance toward reserves or cash to close, usually at a discount. The discount reflects volatility, and a single-ticker position is more volatile than a diversified one. Across the network, expect lenders to apply a larger discount to a concentrated holding and to ask for recent statements. The size of the discount and whether it can fund the down payment, rather than only reserves, differ by program.

Market surveys from lenders report brokerage haircuts in the range of 10% to 30%, but those are market-wide claims, not network figures. Lendmire’s own guidance is to confirm the discount for the specific program before building the file around it.

Route three: borrow against the stock

A securities-backed line of credit lets you keep the shares and defer the sale. It also creates the file’s biggest question mark.

FINRA’s explainer on securities-backed lines of credit says these lines typically allow borrowing from 50 to 95 percent of account value, and that the lender can call the line at any time. The SEC’s Investor.gov alert adds that a maintenance call usually gives a few days to add collateral or repay, after which the firm can sell your securities. The same alert notes a firm may decide a security no longer qualifies as collateral, which cuts your credit limit.

Now connect that to a mortgage file. Line proceeds are borrowed money, not earned or owned cash. Underwriters may treat them as a new liability, may question whether the pledged shares can still count as an asset, and may exclude the draw altogether. Treatment varies by program, and it is the one route where you should get the answer in writing before you draw anything.

Also note that a bank SBLOC is generally non-purpose, meaning it cannot be used to buy securities, while a margin loan is a different product with different terms. Schwab’s explainer on borrowing against assets lays out the distinction.

The Net-of-Tax Problem

What arrives in your bank account is not always what counts toward your file. Say you sell a large block of shares with a sizable gain. You then hold back money for the estimated tax bill. That holdback is not available for the down payment or reserves, because it is already spoken for.

The practical lesson: size the sale to the cash you need after tax, not before it. Selling too little leaves a gap at closing. Selling too much triggers tax you did not need to pay. Underwriters only count what is left in verified, usable form, so build the plan backward from the countable number.

Scale Effects at Super Jumbo Size

Larger loans mean lower leverage and more of your own cash. The ladder, with every figure a ceiling through select wholesale programs and subject to underwriting, runs roughly like this on a purchase:

Loan band Purchase LTV Credit for this leverage
$150K–$1M 80% 660+
$1M–$2M 75% 700+
$2M–$3M 75% 720+
$3M–$4M 65% 700+
$4M–$10M 60% on review 700+

Above $4,000,000, every request is reviewed case by case before submission, purchase or rate-and-term only, with no cash-out. Above $3,000,000, the program adds an overlay: 700 credit, 0x30x24 housing history, 48-month event seasoning, citizens and permanent residents only, and no rural property. Two appraisals are required above $2,000,000.

For a concentrated-stock holder, the practical effect is simple. A $5,000,000 purchase at 60% leverage means a down payment of 40%. That is a big liquidation, and it is why the sourcing paper trail matters most at the top of the ladder. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.

Cash-out has its own limits. Proceeds are unlimited at or below 60% LTV, capped at $1,500,000 above 60%, and unavailable above $3,000,000. Cash-out never satisfies reserves above $3,000,000. For the broader rule differences at this size, see Lendmire’s comparison of super jumbo and jumbo loans. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.

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.

DSCR loan

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.
Conventional loan

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.

A Worked Example

Picture an investor who holds most of her net worth in one technology stock, held for several years. She wants to buy a luxury rental at a price in the $3M–$4M band, at 65% purchase leverage, with rent covering the payment at roughly 1.1x.

Here is how a sound file comes together:

  • Early: She confirms the loan structure and the cash need, including 6 months of reserves, or 12 if she is a first-time investor.
  • Plan the sale: She sells enough shares to cover the down payment, closing costs, reserves and the estimated tax holdback, since holdback cash will not count.
  • Document: She keeps the sale confirmation, the brokerage statements before and after, and the bank statement showing the proceeds arrive.
  • Explain: She writes a short letter tying the large deposit to the stock sale.
  • Keep reserves separate: Reserve funds stay in the account and are not used for the down payment. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.

If a portion cannot be sourced, the usual outcome is that the lender excludes that piece, not that the file ends. The question then becomes whether the remaining funds still cover the need. That is why starting early matters: the problems that sink these files are documentation problems, not credit problems.

Where the General Rule Breaks

The step-by-step process holds for most files. These edge cases are where it bends.

Borrowed cash is not verified cash. An SBLOC draw right before closing creates a large new deposit and possibly a disclosed debt. Confirm how the program treats it before you draw.

Cash-out from the subject property. Money you will receive at closing cannot prove you can carry the loan. Above $3,000,000 it never satisfies reserves.

Entity title. Many DSCR loans close in an LLC, subject to lender program eligibility, and entity vesting is welcome, though layered entities are not. But the stock is usually owned by you personally. Funds may need to move into the entity, or ownership of the funds must be documented.

Restricted, locked-up or unvested shares. Employer stock under lock-up or unvested equity may not count as liquid. Describe the restriction to the lender up front, and expect the shares to be excluded until they are free to sell.

Gifted shares. For tax purposes a gifted asset’s holding period carries over from the giver, as Wealth Enhancement Group explains. Lender rules for gifted funds on DSCR files are a separate question and program-specific.

Double-counting. The same dollars cannot serve as pledged collateral, reserves and the down payment all at once.

Last-minute sales. A sale made days before closing leaves little room to assemble statements and answer questions. Staged sales over time are cleaner, though insider trading windows may limit when you can sell.

Common Mistakes

  • Assuming net worth substitutes for liquid funds.
  • Drawing on a line before confirming how the program treats it.
  • Forgetting the tax holdback when sizing a sale.
  • Counting the same money twice.
  • Treating a wire receipt as proof, when underwriters want statements showing the deposit.
  • Waiting until the contract is signed to start documenting.

What the Decision Looks Like in Practice

The choice usually comes down to your tolerance for tax cost versus your tolerance for risk. Selling uses up the tax deferral but produces clean cash. Pledging defers tax but leaves you exposed to a callable line, and because the stock is also the collateral, a drop hits you twice: the collateral shrinks and the cushion shrinks with it.

If the position is large and the stock is volatile, selling a slice and keeping the rest is often the simplest path. If you are a first-time investor, remember the 12-month reserve requirement. Coverage matters too: 1.00 earns full leverage, while coverage from 0.75 to 0.99 is a real path through select programs to $2,000,000 at reduced leverage, with LTV and terms adjusting, subject to underwriting.

Lendmire is a broker arranging financing through select lenders in its wholesale network across 41 markets, including Washington, D.C., and nothing here is a commitment to lend.

Frequently Asked Questions

Do I have to sell my stock to qualify?

Not always. Some programs count brokerage balances toward reserves, usually at a discount, so you may keep part of the position. But the down payment and closing costs typically need to be cash you can show, so most concentrated holders sell at least part. The right mix depends on the program and the size of the loan.

Can line or margin proceeds count as my funds?

It depends on the program. Borrowed money may be treated as a new liability, and the pledged shares may or may not still count as an asset. A bank securities-backed line is generally non-purpose, so confirm treatment in writing before drawing, and keep the draw record.

What if a deposit cannot be sourced?

The lender usually excludes that piece instead of ending the file. Then the question is whether the remaining sourced funds still cover the down payment, closing costs and reserves. A sourcing letter and statements often resolve it.

Does a tax holdback reduce my reserves?

Yes, in practice. Money set aside for the tax bill is already committed, so it should not be counted toward reserves or the down payment. Size the sale so the leftover, usable cash still meets the requirement.

Do restricted shares or RSUs change anything?

Yes, they can. Locked-up or unvested shares generally do not count as liquid until you can sell them. Once sold, the proceeds follow the same paper trail as any other sale. Tell the lender about the restriction early.
