The HELOC and other ways to use existing equity

Most people entering real estate have their capital tied up in a property they already own, usually their home.

Several mechanisms convert that into deployable funds, each with a distinct risk profile.

Home equity line of credit

A revolving line secured by a property, typically in second position behind the existing mortgage.

You draw what you need, pay interest only on the drawn balance, repay, and draw again during the draw period. After that, it converts to a repayment period.

Advantages. Flexibility — funds available without a new loan each time. Interest only on what is used. Relatively low closing costs. Fast access, which matters for opportunistic purchases.

Disadvantages. Almost always variable rate, so the payment moves. Lenders can reduce or freeze lines, and did so extensively during past downturns, precisely when borrowers needed them. And it is secured by your home.

The freeze risk is the one people forget. A line established as an emergency reserve is not a reserve if it can be cancelled when the emergency arrives.

Cash-out refinance

Replacing the existing mortgage with a larger one and taking the difference in cash.

Advantages. Fixed rate available. One loan rather than two. Typically better rates than a second lien.

Disadvantages. Higher closing costs. Resets amortization. And if your existing rate is well below current rates, refinancing the whole balance to access a portion of the equity is expensive — you reprice all of it to access some of it.

That last point has been decisive for many owners holding low-rate mortgages. A HELOC leaves the first mortgage untouched.

Home equity loan

A fixed-rate second lien for a lump sum, amortizing.

Sits between the two: fixed rate, lump sum rather than revolving, leaves the first mortgage in place.

Suitable where you know exactly how much you need and want payment certainty.

Portfolio lines of credit

For investors with several properties, some banks offer lines secured against a portfolio rather than a single property.

Generally arranged with community banks and credit unions, and they require a relationship.

Useful for acquisitions, since they allow effectively cash offers with speed, followed by permanent financing after closing.

The risk, stated clearly

Every one of these converts equity into debt secured by property you own.

If the investment funded by that debt underperforms, the obligation remains. And where the security is your home, the consequence of failure includes your housing.

The specific failure mode: using a home equity line to fund the down payment on a rental, so the rental is effectively one hundred percent financed across two loans.

The rental's cash flow must service both the rental mortgage and the line. If it does not, you fund the shortfall from your income — and if that becomes impossible, the exposure reaches your home.

This is the mechanism behind a great many personal financial disasters in past cycles.

Using it sensibly

Only when the return exceeds the cost with real margin. Borrowing at eight percent to earn seven is a slow loss. Borrowing at eight percent to earn nine is a one point margin against substantial risk, which is not obviously worth taking.

Count the total leverage. A rental purchased with a borrowed down payment is not seventy-five percent leveraged. It is fully leveraged with the debt split across two instruments.

Calculate coverage against total debt service including the line.

Prefer short-term, defined use. A line used to fund a renovation, repaid from a refinance or sale on a defined timeline, is a bridge with a clear exit.

A line used to fund a permanent down payment, with no repayment plan, is permanent additional leverage.

Do not use variable rate debt for long-term positions without modelling the payment at substantially higher rates.

Keep a line undrawn as liquidity, understanding that it may not be available when needed, and therefore is not a substitute for cash reserves.

The interest deduction question

Tax treatment of interest on home equity borrowing depends on how the funds are used, and the rules changed under recent legislation.

Broadly, interest may be deductible where proceeds are used for investment or business purposes, subject to tracing requirements and various limitations.

The tracing rules require documentation of how the funds were actually used, which means keeping records at the time rather than reconstructing them later.

This is an area requiring a tax professional. Do not assume deductibility.

The conservative position

Equity in a paid-down property is a genuine asset. It is also, in a downturn, the thing that lets you survive.

An investor with substantial unencumbered equity and modest debt has options: they can borrow when others cannot, buy when prices are low, and carry properties through bad periods.

An investor who has extracted every available dollar of equity has none of those options, and is one bad year from a forced sale.

The equity is doing work even when it appears idle.
