If you want a pool in Arizona and you hold a mortgage rate near 3%, the cash-out refinance is probably the wrong tool. If your rate is already close to today's rates, it may be the right one. That single question, how your current rate compares to the market, decides almost everything. A pool is a $60,000 to $100,000 decision in the Valley, so it is worth running both payments before a contractor ever pours concrete. Here is how the refinance, the HELOC, and the other options compare for a homeowner in Scottsdale, Phoenix, or anywhere in Metro Phoenix.

Should you refinance to pay for a pool?

Only if the new rate on your whole balance beats the cost of borrowing the pool money separately. A cash-out refinance replaces your entire loan. Every dollar you owe gets the new rate, not just the pool money. That is a fine trade when your old rate is high. It is an expensive trade when your old rate is low.

Our deeper comparison of cash-out refinance vs HELOC covers the general rule. This post applies it to one project, with one set of numbers, so you can see how big the gap really gets.

The math on a $75,000 pool

Take a home worth $650,000 with a $280,000 balance at 3.25% and about 25 years left. Your current principal and interest payment is about $1,364. You want to borrow $75,000 for a pool. That puts you at a combined loan to value of about 55%, well inside the 80% limit most lenders use for a conventional cash-out loan on a primary home.

The two paths look very different. In a cash-out refinance, the new loan is $355,000. At an illustrative 7.24% for 30 years, the payment is about $2,419, which is $1,055 a month more than today. With a HELOC, you keep the 3.25% first mortgage and borrow $75,000 separately. At an illustrative 9% on a 20 year repayment, the extra payment is about $675. The table puts them side by side.

Run your own numbers

These rates are illustrations, not quotes. HELOC rates are variable and can rise, and cash-out loans often price a bit above a plain rate and term loan. Even so, the HELOC path costs roughly $380 less per month in this example, and you skip the closing costs on a full refinance. For a homeowner with an old low rate, that gap is the whole story. Our guide to the mortgage lock-in effect explains why so many owners feel stuck, and our piece on home equity loans vs cash-out refinances covers the fixed-rate second mortgage option.

When the refinance wins

Flip the example. If your current rate is 7% or higher, the cash-out refinance costs you almost nothing in rate, and you get one payment with a fixed rate. You can also fold a high interest HELOC or other debt into the new loan. If your rate is above where the market is today, you might lower it on the old balance and pay for the pool with the equity at the same time. Check the closing costs against your savings with the refinance break even point, and use the calculator above to test a payment.

Cash at closing versus cash as you build

A cash-out refinance hands you a lump sum at closing. Pool builders in the Valley typically take deposits and progress payments through the build, so that money sits in your account while the permit, excavation, and plaster stages move along. A HELOC lets you draw as the contractor bills you, and you pay interest only on what you have drawn. If you refinance, expect a three business day right of rescission on a primary home before funds are released, which we explain in right of rescission on a refinance.

What the appraiser will and will not give you

A cash-out refinance is appraised on the home as it stands today. There is no credit for a pool you have not built. If you want the loan sized on the finished value, that is a renovation loan, which we cover in renovation loans in Arizona. Once the pool is done, appraisers often credit it for less than you paid, so do not assume the value rises by the cost. For help with the lender's side of the appraisal, see our guide to the appraisal for a refinance.

What a pool costs after the loan is funded

The payment is only the first bill. A Valley pool runs a pump nearly year round, needs chemicals and cleaning, and sooner or later needs equipment and resurfacing. Many owners also see a bump in homeowners insurance because of the added liability, so ask your agent for a quote before you commit. Add those costs to the loan payment and compare the total to what you would actually enjoy. If the all in number stretches your budget, a smaller plunge pool or a phased build may fit better than the full backyard plan. Be honest about how often your family will swim from November to March, too.

Other ways to pay for it

You can use cash, a pool specific unsecured loan, or a home equity loan. Unsecured loans move fast and put no lien on your house, but they usually carry higher rates and shorter terms. A fixed rate home equity loan gives you a steady second payment. Whatever you pick, read the loan estimate line by line. The Consumer Financial Protection Bureau's home loan resources explain how to compare offers, and the IRS explains the rules on improvement debt in Publication 936. A tax professional can tell you whether your pool financing qualifies.

Before you sign a bid, confirm the permit rules in your city and check your HOA requirements. A pool also changes your insurance and your resale picture.
