Most articles about tapping your home equity give you a list of things you could spend it on. That list is the easy part. The hard part, and the part that actually costs people money right now, is how you get at it. Because if you bought or refinanced before 2022, the way you go about tapping your home equity can be the difference between an extra $625 a month and an extra $1,331 a month for the exact same $100,000.
Why tapping your home equity is a different question now
The reason has nothing to do with what you plan to spend the money on. It comes down to the loan you already have. Per Redfin’s rate lock analysis, the share of mortgaged American homeowners sitting on a rate below today’s market is enormous:
- 80.3% have a rate below 6%
- 70.4% are below 5%
- 52.5% are below 4%
- 20.4% are below 3%
That low rate is an asset. It is not as visible as the equity, but it has a dollar value, and a cash-out refinance spends all of it to access a slice of the house. Which flips the usual advice. The conventional wisdom says to take the lowest rate available on the money you are borrowing. In this environment, the better question is which option leaves the rest of your balance alone.
The $10,500 difference, on a real example
Take a Monmouth County owner with a $400,000 balance at 3.5% who wants $100,000 for a renovation. Their payment today is about $1,796 in principal and interest. Option one: cash-out refinance to $500,000. At roughly 6.4%, the new payment is about $3,128. That is $1,331 more a month. Option two: keep the first mortgage and add a $100,000 second. At around 7.5% on an interest-only draw, the added cost is about $625 a month. Fully amortizing it over twenty years runs about $806. So the higher-rate option is cheaper. By a lot. The reason is that a refinance reprices the whole balance. Look at first-year interest and it is stark: about $32,000 on the refinanced $500,000, against about $21,500 if you keep the 3.5% first and layer a 7.5% second on top. That is roughly $10,500 a year in favor of the option with the scarier rate. The 7.5% applies to $100,000. The 6.4% would apply to $500,000. That is the entire trick.
What each way of tapping your home equity actually is
Cash-out refinance. One new first mortgage replacing the old one. Makes sense only if your current rate is at or above market, or if you need a very large sum. HELOC. A revolving line secured by the house, usually at an adjustable rate, sitting behind your first mortgage. The CFPB has a plain-language explanation. Best when you do not know the final number, as with a renovation that may grow. Home equity loan. A fixed-rate, fixed-term second mortgage funded in a lump sum. Best when you know the number and want a payment that does not move. Reverse mortgage. For owners 62 and older, with real trade-offs, and worth a conversation with a HUD-approved counselor rather than a lender’s loan officer. Selling. The option people forget to put on the list. It is the only one that accesses all of the equity and none of it costs interest.
Four uses that hold up around here
Not every reason for tapping your home equity holds up. Here are the ones I actually see work in Monmouth and Ocean County. Pre-sale work on a house you are about to list. Short hold, clear payoff, and the loan comes off at closing. This is the cleanest use there is, though I would check which updates actually pay back locally before deciding how much you need. Buying the next house before selling this one. In a market where the right smaller house draws five offers in a weekend, being able to buy without a sale contingency is worth real money. This is the usual answer to the sequencing problem I described in the piece on downsizing and the property tax math. Retiring genuinely expensive debt. A 7.5% secured second against 22% card balances is arithmetic, not strategy. The caution is that you have converted unsecured debt into debt attached to your house. Flood mitigation. Specific to this area and frequently overlooked. Elevation work, utility relocation, flood vents and a current elevation certificate can move an insurance premium substantially, and in a coastal market that premium affects what a buyer can afford to pay you later.
The New Jersey wrinkle that limits how much you can get
Here is the local detail that catches people, and no national article is going to tell you about it. How much you can borrow when tapping your home equity is not purely a function of how much you have. Lenders do not just look at your equity. They look at your debt-to-income ratio, and that calculation includes property taxes and insurance. The Middletown average residential tax bill runs about $11,666 a year. That is roughly $972 a month landing in your DTI before you have borrowed a dollar. In Rumson it is closer to $1,967 a month. An identical borrower with an identical income in a low-tax state has hundreds of dollars a month more room than you do. Which means two owners with the same equity and the same paycheck get very different answers here, and the limiting factor is usually income rather than equity. Worth finding out which one binds for you before you plan around a number.
When tapping your home equity is the wrong move
For anything that does not outlast the loan. A thirty-year obligation against a vacation is a bad trade regardless of the rate. If you are selling within a year or two. Closing costs on a second do not amortize over eighteen months, and the balance comes off the top of your proceeds anyway. If the payment only works on paper. HELOC rates are adjustable. Price the payment at a rate two points higher than today’s and see whether it still works. If it funds a project with no resale payoff. Pools, additions and high-end finishes above what the street supports do not come back at closing.
The bottom line
Tapping your home equity is often the right call around here, because owners are holding a lot of it. I have written about how far ahead long-term owners still are separately. Just do not let a lender quote you the lowest rate on the screen without comparing it to the one you already have. On a sub-4% first mortgage, the highest-rate option is frequently the cheapest one, and the difference runs into five figures a year. If you are weighing equity against selling, or want to know what your house would actually appraise for before you talk to a lender, get in touch and I will put a current valuation together.

Rate-lock figures reflect Redfin’s analysis of mortgaged U.S. homeowners as of Q2 2025. Payment and interest figures are illustrative, principal and interest only, and depend on your actual rate, term, credit, and loan-to-value. HELOC rates are variable and can rise. Average property tax figures are 2025 municipal averages and differ from any individual bill.
