Buying a second home often raises a question that is more complicated than the purchase itself: Where should the money come from?

You may have enough wealth to afford the property comfortably, yet much of that wealth could be invested in securities with substantial unrealized gains. Paying cash could require a sizable tax bill. Borrowing could preserve those investments while adding interest expense and risk.

The right approach depends on what each choice means for your taxes, cash flow, portfolio, and financial flexibility after closing.

Start by deciding how much liquidity you want to keep.

Before choosing a funding source, calculate the full amount needed. Include closing costs, furnishings, renovations, and a reserve for unexpected expenses. Then estimate the ongoing cost of owning both homes:

• Property taxes and insurance, including any separate flood or wind coverage.
• Maintenance, utilities, landscaping, and property management.
• Association fees and potential special assessments.
• Mortgage payments and other borrowing costs.

Decide how much accessible money should remain for your regular spending, tax obligations, and other goals. That reserve helps establish how much you can comfortably put toward the purchase.

Using existing cash can simplify the decision.

If you have substantial cash beyond those reserves, paying cash eliminates loan interest and required debt payments. It also reduces the amount your portfolio must provide each month.

The trade-off is liquidity. Money invested in a home cannot be accessed as easily as money in a bank or brokerage account. Consider how much of your net worth would be tied up in real estate after the purchase.

Compare the interest you would avoid with the after-tax yield on the cash you would use. This is a more direct comparison than measuring a loan rate against an optimistic stock market forecast.

Selling investments requires looking beneath the account balance.

The tax cost depends on which investments you sell, their cost basis, your holding periods, and your broader tax situation. Capital losses may offset gains, and long-term gains generally receive different federal treatment from short-term gains.

Consider a hypothetical example:

• You sell $500,000 of investments with a $200,000 cost basis.
• The sale creates a $300,000 capital gain.
• Assuming an illustrative combined tax rate of 25% on that gain, the tax is $75,000.
• That leaves $425,000 available after reserving for taxes.

If you need the full $500,000 for the property, you would need additional funds to cover the tax.

Before selling, review individual tax lots—the shares purchased at different times and prices. Higher-basis shares may provide cash with less taxable gain. Selling can also be an opportunity to reduce an oversized position.

A tax bill deserves careful planning, but paying some tax may be reasonable if it improves diversification and avoids years of borrowing costs.

A mortgage can preserve liquidity and spread the cost over time.

Financing part of the purchase may let you retain investments while keeping a meaningful cash reserve. A fixed-rate mortgage provides predictable principal and interest payments, although taxes, insurance, and other ownership costs can change.

Compare actual Loan Estimates, including interest, points, lender fees, and payments. Evaluate costs over the period you expect to keep the loan, especially if you anticipate paying it off early.

Be cautious about assuming your portfolio will earn more than the mortgage costs. Investment returns are uncertain; required loan payments continue through weak markets. Include taxes and investment fees in the comparison.

Also, have your CPA confirm any mortgage-interest deduction. Eligibility depends on itemizing, qualifying secured debt, and applicable limits across your primary and second homes. A second property does not automatically create a separate deduction allowance.

Borrowing against a portfolio introduces different risks.

A securities-backed line of credit allows you to borrow using eligible investments as collateral. It can provide temporary funding while you await another property sale or arrange longer-term financing.

However, keeping the investments also means retaining their market risk while adding debt:

• Rates are commonly variable, so interest expense can rise.
• Falling portfolio values or changes in collateral requirements can trigger demands for additional collateral or repayment.
• The lender may sell investments if you cannot meet those demands, potentially realizing taxable gains.
• The lender may have the right to demand repayment even before your intended payoff date.

Interest on portfolio borrowing used to purchase a personal-use home generally is nondeductible personal interest. Pledging investments does not, by itself, make the interest an investment expense.

If the line is intended as a bridge, establish the repayment source, timing, and backup plan before borrowing.

A combination may fit best.

You might use surplus cash, sell selected investments, and finance the balance. This can help balance the immediate tax cost with ongoing payments and the liquidity you want to retain.

Before committing, test the plan against less favorable conditions:

• Could you carry both homes if your portfolio declined substantially?
• Could you handle higher borrowing costs or a major repair?
• Would the purchase remain affordable without expected rental income?
• Could you repay temporary financing if another property sale were delayed?

At Bishop Capital Advisors, we help clients evaluate these decisions alongside their investment strategy and financial plan, coordinating with their CPA and lender. The funding approach should leave you comfortable with both the purchase and the financial commitments that follow.
