How to Buy a Houston Luxury Home Without Selling Your Stock Portfolio

You do not have to sell your stock portfolio to buy a luxury home in Houston. Two financing tools let a buyer put real money down without forcing a taxable sale: a securities-backed line of credit that borrows against your investments while you keep them, and an asset-depletion mortgage that counts your liquid assets as income instead of a paycheck. Both exist because plenty of wealthy buyers have more sitting in a brokerage account than showing up on a W-2.

Peter spent years in construction and mortgage lending before real estate, and that is exactly the background that makes a buyer’s financing structure something he reads line by line instead of waving through.

Two Ways to Buy Without Touching Your Portfolio

Most mortgage underwriting still wants a paycheck. A business owner, a retired executive, or someone who built most of their net worth in stock options does not always have one, even with millions in assets sitting a few clicks away. Two structures solve that problem in different ways.

A securities-backed line of credit, usually shortened to SBLOC, is a revolving line from a brokerage or private bank, collateralized by stocks, bonds, or mutual funds you already own. You do not sell anything. You borrow against it, write a check for the house, and your portfolio stays invested. The interest is normally variable, the payments are interest-only, and most lenders advance somewhere between 50 and 70 percent of the pledged securities’ value, less for one concentrated stock position.

An asset-depletion mortgage works differently. The lender takes your liquid assets, checking, savings, brokerage, retirement accounts, and divides them over a set number of months, often 360, to produce a monthly income figure for qualification, similar in spirit to what we see for self-employed buyers who can’t document income the usual way. No pay stubs, no tax returns showing business income you reinvested instead of paying yourself. You still owe a real monthly payment on a loan that still has to be repaid.

The Risk an SBLOC Doesn’t Advertise

I was going to call this clever. It is clever, until the market drops and clever turns into a call from your lender at a bad hour.

An SBLOC is a demand loan. If the market falls and your pledged portfolio drops below what the loan requires, the lender can issue a call: deposit more cash, pledge more securities, pay down the balance, or watch the lender sell your stock for you. A sharp drop can hand you the exact outcome you borrowed to avoid, a forced, badly timed sale, with the lender choosing the timing instead of you. We have watched a client’s financing come apart during an option period for a reason that traced back to exactly this, and it is the first thing we now ask about.

Which Tool Fits Which Buyer

A rough way to sort it:

• Have a concentrated, appreciated stock position you don’t want to sell yet? An SBLOC buys you time.
• Retired, or between business cycles, with real assets but no current paycheck? Asset depletion gets you qualified on paper.
• Need the money tied up for more than two or three years, or buying into a market that already feels stretched? Either one can turn into a problem you didn’t plan for.

Neither tool replaces the mortgage underneath it. Most Houston luxury purchases above the conforming loan limit still run through jumbo loan underwriting, with its own down payment, reserve, and appraisal requirements, whatever the income side of the file looks like. The financing tool changes how you qualify. It does not change what the house still has to appraise for, or what reserves the lender wants sitting in the bank after closing.

The Tax Math Behind the Decision

Here is the math that makes both of these worth the paperwork. Sell enough stock to write a check for a multi-million dollar home, and the federal long-term capital gains rate alone runs 15 to 20 percent, per the IRS, and Texas adds nothing on top of that since the state has no capital gains tax. Borrow against the same stock instead, and nothing gets sold, so nothing gets taxed. Not yet, anyway. Both of these loans eventually get repaid, usually from the sale of something, so this is a timing strategy, not a way to make the tax disappear.

We would rather a buyer ask their CPA or wealth manager this question before they ask us, and most ask us first, which backwards as that sounds, is exactly why we wrote this. We are not your lender. We will tell you plainly when a question belongs with your tax advisor instead of us. The Move Live Love TX Team is a husband-and-wife real estate team serving Houston and the surrounding areas, helping luxury buyers and sellers, with a Certified Luxury Home Marketing Specialist on every listing, and part of that job is asking a buyer’s lender pointed questions before we ever write an offer on their behalf. What happens to this loan if the appraisal comes in low. What happens to the buyer if the market drops 15 percent between contract and closing.
