The Quick Read: A jumbo cash-out refinance fits you if you want a clean exit for the departing partner and one new mortgage. A securities-backed line fits you if you hold a large, diversified portfolio and can live with market risk. The refinance puts the house at stake. The line puts your portfolio at stake. Which risk you would rather carry usually decides the question.
“Partner” here means a co-owner of the home you live in. That could be a spouse, ex-spouse, sibling or co-buyer. You keep the house and pay the other person their share of the equity.
Key Takeaways
- A jumbo cash-out replaces your current mortgage with one new loan. The departing partner can come off the debt when the old loan is paid off.
- A securities-backed line leaves the mortgage alone. The departing partner usually stays on the old note unless the mortgage is refinanced or assumed.
- The refinance depends on your income, credit, reserves and the appraisal. The line depends mostly on your portfolio.
- The refinance risk is foreclosure. The line risk is a margin call and a forced sale of your investments.
- Many people use the line as a bridge and then refinance. That is a legitimate plan, but it needs an exit date you can defend.
Side-by-Side
The table compares the two paths on structure, not price. Jumbo figures come from the wholesale programs Lendmire places files with. Lender guidelines and full file review decide what applies to you.
| Factor | Jumbo Cash-Out | Securities-Backed Line |
|---|---|---|
| Collateral | Your home | Your investment account |
| Leverage | Cash-out sits below purchase leverage | Set by the portfolio and the lender |
| Credit floor | 660 decision score on the headline lane | Mostly portfolio-driven |
| Mortgage insurance | Depends on lane and leverage | None; it is not a mortgage |
| Occupancy | Primary home; leverage shifts by occupancy | Not tied to the home |
| Documentation | Income, assets, credit, appraisal | Account statements, pledge agreement |
| Partner release | Old note paid off; partner removed | Existing mortgage usually stays |
| Downside | Foreclosure risk | Margin call, forced sale |
| Repayment shape | Fixed, adjustable or interest-only lanes | Interest-oriented; draw can be repaid and re-borrowed |
A few notes on the jumbo column. The headline lane runs leverage up to 90% on a purchase. Cash-out lands lower, and the largest lanes add a cash cap. Loans run to $5,000,000 on the largest lanes. The ratio ceiling is 50% on the fixed lanes, 45% on the adjustable lane and 43% on the interest-only lanes. Reserves are counted in months of the full payment and rise with the loan amount. Above a lane’s threshold amount, expect two appraisals. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.
What Does “Jumbo” Mean Here?
A jumbo loan starts one dollar above your county’s conforming limit. The Federal Housing Finance Agency sets that limit each year, and it varies by county and unit count. Check your own county in the FHFA’s published limit values.
Why it matters: a buyout often pushes the new loan past that line. Jumbo loans are not bought by Fannie Mae or Freddie Mac. Each lender sets its own rules. So the conforming guidelines you read online are a reference point, not your answer.
When a Jumbo Cash-Out Is the Better Fit
Choose the refinance when the partner’s exit has to be final. A new first mortgage pays off the old one. The old note goes away, and the departing partner comes off the debt. Title moves to you. Nobody has to wonder who still owes what.
That clean break is the main reason people pick this path. A buyout after a divorce is the classic example. A former spouse often wants out of the loan entirely, and a lender or court order may require it. A securities-backed line cannot do that by itself.
This path also fits you when:
- Your wealth is mostly in the house. If you have little in investments, a portfolio line is off the table.
- You want predictable repayment. The jumbo lanes offer fixed, adjustable and interest-only structures. You choose the shape.
- You want no margin-call exposure. A mortgage does not get called because the stock market had a bad week.
- Your income carries the loan. You qualify alone, on your own income, credit and reserves.
Here is the catch. You are the only borrower now, and the file is judged on you. Across the wholesale programs Lendmire works with, the 660 decision score on the headline lane is a floor, not a promise. The ratio ceilings above are limits, not targets. A buyout that pushes your ratio near the ceiling leaves little room for error.
Two more mechanics matter. First, lenders often treat a buyout refinance as a cash-out. Cash-out leverage sits below purchase leverage, and the largest lanes cap the cash. Ask early how a buyout is classified, because that decides how much the loan can reach. Second, the old rules from the agencies may not carry over. Fannie Mae’s cash-out refinance guidance exempts a co-owner buyout under a legal agreement from its 12-month loan-age test. It also expects a borrower to have been on title for six months. Those are conforming rules. A jumbo lender may set different overlays, so do not assume the same exemption.

When a Securities-Backed Line Is the Better Fit
Choose the line when you have a large portfolio, you do not want to sell it, and the buyout is a bridge rather than a permanent plan. A securities-backed line is credit secured by your investment account. It is “non-purpose” credit. You can use it for most things except buying more securities or paying down a margin loan. A buyout payment is a permitted use, though each lender decides which holdings count and how much to advance.
The appeal is plain. You keep your investments in the market. You avoid selling positions and triggering gains. You do not put a lien on the house. And the line is revolving, so you can repay it and borrow again. The Federal Reserve notes that these loans are usually structured as lines of credit. It also cites a market-wide range of roughly 50 to 95 percent of account value. That is a general range across the market, not any lender’s offer.
This path fits you when:
- You have a clear exit. A bonus, a sale or a planned refinance will repay the draw.
- Your portfolio is diversified. A single concentrated stock can trigger a call from one bad event.
- The departing partner is not on the mortgage, or can stay on it for a while by agreement.
- You can absorb a drop. You have other liquid money to post if the lender asks for more collateral.
Now the part the marketing skips. A line can become a demand loan, which means the lender may call it. FINRA explains that if your securities fall far enough, you get a maintenance call. You must add collateral or repay, typically within two or three days. If you cannot, the firm can sell your holdings. Interest on these lines usually floats and is charged monthly. So the cost can change while you carry the balance.
That is not a theoretical risk. Picture a buyout funded by drawing a large share of a stock-heavy portfolio. A market drop of roughly 30% (an illustration, not a forecast) leaves you with less collateral and the same balance. You may be selling at the bottom to meet the call. A refinance has no such trigger.

Can a Securities-Backed Line to Buy Out a Partner Work With a Mortgage Still in Place?
Yes, mechanically. The line pays the partner, and the mortgage sits where it was. But the departing partner’s name usually stays on the old note unless it is refinanced or assumed. Check this with your servicer and a title or legal professional before you sign anything. Do not assume the line cleans it up.
There is a second wrinkle. If you later apply for a mortgage, the underwriter looks at the line. Fannie Mae’s guide, for example, lets payments on loans secured by financial assets stay out of long-term debt. It also reduces the value of the pledged asset when it counts as reserves. A jumbo lender can treat the line differently. It may assign its own payment to the balance, which affects your ratio and your reserves. Ask before you draw, not after.
How Does Each Path Treat the Departing Partner?
A refinance rewrites the debt. The old loan is paid, a release is recorded, and title goes to the remaining owner. That is the full exit.
The line does not rewrite anything. It gives you the cash. The deed and the mortgage are separate steps. If the departing partner is on both, you still have work to do. Many people do the line first, sign the deed, then refinance once the timing and the ratios allow.
Whichever path you pick, get the buyout terms in writing. A settlement agreement, divorce decree or signed buyout agreement tells the lender and the title company what was agreed and how the money is split. Lenders will want to see it. For a refinance, they will also want to see how the proceeds are disbursed.
Which Documents Will Each Lender Ask For?
For the jumbo refinance, expect the usual file:
1. Income documents and credit for the remaining owner.
2. Asset statements to cover reserves, measured in months of the full payment.
3. The signed buyout or settlement agreement.
4. An appraisal, or two above a lane’s threshold amount.
5. Title work and payoff statements.
The securities-backed line asks for different things:
1. Statements for the account being pledged.
2. A pledge or control agreement.
3. A lender review of which securities are eligible.
4. The stated purpose of the draw.
A refinance has a full closing: appraisal, title, payoff and recording. The line usually skips mortgage-style closing but adds account setup and collateral review. Lender fees vary on both sides, so compare the full terms on each lender’s disclosures.
What Goes Wrong With Each Path?
Refinance problems:
- The appraisal comes in below the number you need, so the loan reaches less than planned.
- Your ratio lands above the lane’s ceiling once you are the only borrower.
- Reserves are short. They rise with the loan amount.
- The lender treats the buyout as a cash-out and caps the proceeds.
Line problems:
- A market drop triggers a call you cannot meet.
- The cost of carrying the balance changes while you wait for your exit.
- The exit slips. The bonus is smaller, or the sale falls through.
- A later mortgage lender counts the line against your ratio.
Run both stress tests before you choose. For the refinance, ask what happens if the appraisal lands below your expectation. For the line, ask what happens if the portfolio falls by a third and the exit slips by a year.
What If Neither Fits Alone?
Many buyouts are bigger than one tool can fund. Some options:
- Phased buyout. Pay the partner in stages, with part now and part later.
- Seller-style note. The departing partner accepts a note for part of their share.
- A home equity loan or HELOC. These leave the first mortgage intact, unlike a cash-out refinance, which replaces it. The Consumer Financial Protection Bureau describes that structural difference. It also notes that failing to make payments on home-secured debt can lead to foreclosure.
- Bridge, then refinance. Use the line for the payout, then refinance later to clear the partner from the note and retire the line.
That last one is the most common hybrid. It is also the one that depends most on your exit date. (A plan with no date is a hope, not a plan.)
Tax treatment can depend on your situation; borrowers should speak with a qualified tax professional before relying on any deduction or credit.
Key Terms Defined
Jumbo loan: A mortgage above your county’s conforming limit. Each lender sets its own rules.
Cash-out refinance: A new mortgage that replaces the old one and pays out the difference in cash.
Securities-backed line of credit: A revolving credit line secured by your stocks, bonds or funds. You borrow against them instead of selling.
Maintenance call: A demand from the lender to add collateral or repay when your pledged securities fall in value.
Non-purpose credit: Credit that cannot be used to buy more securities or pay down margin debt.
Reserves: Liquid money left after closing, counted in months of your full payment.
A Quick Decision Check
Answer these five questions honestly.
1. Does the partner need to come off the mortgage? If yes, lean toward the refinance.
2. Do you hold a diversified portfolio you would rather not sell? If yes, the line becomes an option.
3. Can your income qualify you alone under the lane’s ratio ceiling? If not, a refinance may not reach.
4. Could you meet a margin call within a few days if markets fell sharply? If not, be careful with the line.
5. Do you have a dated exit for the line? If not, the line is a weaker choice.
Mixed answers are normal. They often point to the bridge-then-refinance sequence.
The Balanced Verdict
Neither option wins on its own terms. The refinance is cleaner and sturdier. It releases the partner, fits a long hold and does not depend on markets. But it makes you qualify alone, and it puts the house on the line.
The securities-backed line is flexible and keeps your investments working. But it carries market risk on a short clock, does not release anyone from the mortgage, and needs a real exit. For many homeowners, the line works best as a short bridge to a refinance, not as a permanent answer.

Frequently Asked Questions
Can I use a securities-backed line to buy out a partner on my home?
Usually yes, if the lender permits it. A buyout payment is not a purchase of securities, so it generally fits the non-purpose rule. Each lender decides which holdings count and how much to advance. Confirm the stated use with the lender before you draw.
Does a jumbo cash-out refinance release my partner from the loan?
Generally, yes. The new loan pays off the old mortgage, and a recorded release removes the old note. Title then moves to you. Confirm the sequence with your title company, because the deed and the payoff happen as separate steps.
Will a lender count the securities-backed line against me?
It may, depending on the lender. Some guidelines let payments on loans secured by financial assets stay out of long-term debt and reduce the pledged asset’s value as reserves. A jumbo lender can assign its own payment, which affects your ratio and reserves. Ask before you draw.
How fast can a margin call arrive?
It can arrive after a sharp drop in your pledged securities. FINRA describes a typical window of two or three days to add collateral or repay. That is a short clock for a large balance.
Is the 660 score enough to qualify for the jumbo refinance?
It is the floor on the headline lane, not a guarantee. Your ratio, reserves, appraisal and the loan amount all count. Ratio ceilings run 50% on the fixed lanes, 45% on the adjustable lane and 43% on the interest-only lanes. A lender reviews your full file.
