If your home still fits your life, refinancing or tapping your equity usually makes more sense than selling. If it doesn't fit anymore because of space, location, schools, a job change or a growing family, selling and moving up, or keeping it as a rental, usually makes more sense. The right answer comes down to three things: whether you want to stay in the house, what your current mortgage rate is, and how much equity you have to work with.
I'm Paul Mattos, a mortgage broker in Fort Mill, SC, licensed in North and South Carolina. Homeowners ask me this question all the time, especially people who bought or refinanced when rates were low and now feel stuck. Here's how I walk through it with clients.
Start With One Question: Do You Want to Stay?
Before you look at any numbers, decide whether the house still works for you.
Signs you may want to stay and refinance or borrow against your equity:
You like the location, the schools and the neighborhood.
The house could work with an addition, a finished bonus room, a renovated kitchen or an ADU.
Your current mortgage rate is low and you don't want to give it up.
Moving would mean higher prices, higher property taxes or a longer commute.
Signs you may want to sell or move up:
You've simply outgrown the house, and a renovation can't fix the layout or lot.
You need to be in a different area for work, family or schools.
You want a different kind of home, like a one-story, more land or less upkeep.
The cost of renovating would come close to the cost of moving.
Once you know which way you're leaning, the financing choice gets much clearer.
Option 1: Stay and Refinance
A refinance replaces your current mortgage with a new one. There are two main types.
Rate-and-term refinance
This changes your rate, your term or both, without taking cash out. It can make sense if current rates are meaningfully lower than your rate, if you want to move from an adjustable rate to a fixed rate, or if you want to remove mortgage insurance. My guide on whether you can remove PMI with a refinance covers that last one.
Cash-out refinance
This replaces your mortgage with a larger one and gives you the difference in cash. On a conventional loan for a primary residence, the new loan is generally limited to 80% of the home's value, and other programs have their own limits.
A cash-out refinance can work well when your current rate is close to today's rates or higher. If your current rate is well below today's rates, it means giving up that low rate on your entire balance just to get the cash, and it also restarts your loan term and brings new closing costs.
Option 2: Stay and Add a HELOC or Home Equity Loan
If you have a low rate on your first mortgage, this is often the option I look at first. A home equity line of credit (HELOC) or a home equity loan is a second mortgage, so your first mortgage stays exactly as it is. You only pay the newer rate on the amount you borrow.
Homeowners use this for:
Renovations, additions and finished bonus rooms
Building an ADU, garage or in-law suite
Paying down higher-interest debt
A down payment on a second home or investment property
HELOCs usually have variable rates, and payments can change. Home equity loans usually have a fixed rate and payment. For a side-by-side comparison, read HELOC vs. cash-out refinance, and if debt is the main goal, should I refinance my low-rate mortgage to pay off debt?
If the project is large, a renovation loan may let you borrow based on the home's value after the work is done. My HELOC page covers how equity lines work in North and South Carolina.
Option 3: Sell and Move Up
If the house no longer fits, selling is often the cleanest path. You take your equity, use it toward the next home and carry one mortgage.
What selling really costs
Your equity isn't the same as what you'll walk away with. Before you count on your proceeds, subtract:
Real estate commissions and any concessions you agree to
Your mortgage payoff
Repairs or credits from the buyer's inspection
Transfer taxes. In North Carolina, the excise tax is $1 per $500 of the sale price. In South Carolina, the deed recording fee is $3.70 per $500. Sellers customarily pay both.
Attorney fees, prorated property taxes and any HOA fees
Moving costs
Taxes on the sale
Under current federal rules, if you've owned and lived in the home as your main residence for at least two of the last five years, you can usually exclude up to $250,000 of gain from your income, or up to $500,000 if you're married and file jointly. Congress has considered proposals to change this, so confirm the current rules with a tax professional before you sell. The IRS explains the details in Topic 701, Sale of Your Home.
Your next payment will probably be different
If you're giving up a low rate, your new payment may be higher even if your loan amount is similar. Moving to a new county or across the state line can also change your property taxes and insurance. That's why I run a Total Cost Analysis on the actual home you're considering before you make an offer, so you can compare the full monthly cost, not just the price.
Buying before you sell
Many move-up buyers want to buy first so they only move once. That can work if you qualify with both payments, use a HELOC on your current home for the down payment, or line up bridge financing. I cover each approach in Can I buy a house before selling mine? If you're moving to the Charlotte area from another state, read buying in Charlotte before selling your home in another state.
Option 4: Keep Your Current Home as a Rental and Buy Your Next One
If you have a low rate and a home that would rent well, keeping it can be a way to start building a rental portfolio without buying an investment property from scratch.
How the rent can help you qualify
Under Fannie Mae's departing residence guidelines, projected rent from the home you're leaving can often be used to help you qualify for the new one, usually based on a signed lease and a percentage of the rent. I explain the details in Fannie Mae's departing residence rental income rule.
What changes when it becomes a rental
South Carolina property taxes can go up. South Carolina's 4% assessment ratio applies only to your primary residence. Once the home becomes a rental, it's generally assessed at 6%, and it loses the school operating tax relief. Factor that higher bill into your rental numbers. In North Carolina, the assessment doesn't change based on whether you live there. See North Carolina vs. South Carolina property taxes.
You'll need a landlord insurance policy instead of a standard homeowners policy.
The tax exclusion on a future sale has a clock. To use the home sale exclusion, you generally need to have lived in the home for two of the five years before you sell. Renting it out for more than three years can mean losing that exclusion. Talk with a tax professional before you decide.
You become a landlord. That means tenants, repairs, vacancies and, if you hire one, a property manager.
If you plan to buy more rentals later, a DSCR loan can qualify future purchases based on a property's rental income instead of your personal income. My investment property loans page covers the options.
Quick Comparison: Which Option Fits?
Refinance (rate-and-term) usually fits if you're staying and today's rates are meaningfully lower than yours, or you want to change your loan type or remove mortgage insurance.
Cash-out refinance usually fits if you're staying, need a larger amount, and your current rate is close to or above today's rates.
HELOC or home equity loan usually fits if you're staying, have a low first mortgage rate you want to keep, and need money for a project or a specific goal.
Sell and move up usually fits if the house no longer works for your life and renovating won't fix it.
Keep and rent, then buy usually fits if you have a low rate, a home that would rent well, enough cash and income to carry both, and you're comfortable being a landlord.
Questions to Answer Before You Decide
How long do I plan to stay in this home if I don't move?
What is my current rate, and how does it compare with today's options?
How much equity do I have, and how much would I actually net from a sale?
What would the renovation or addition cost compared with moving?
What would my total monthly cost be on the next home, including taxes, insurance and HOA dues?
If I keep this home as a rental, would the rent cover the payment, taxes, insurance, repairs and vacancies?
How do the tax rules apply to my situation? A tax professional should answer this one.
How I Help Homeowners Compare
I can run the numbers for each path side by side: your current loan, a refinance, a HELOC, a sale and purchase, or keeping your home as a rental while you buy the next one. As a mortgage broker, I compare options from multiple wholesale lenders, so you're not limited to one bank's programs. If you already have a quote from another lender, send it to me for a mortgage offer review.
Frequently Asked Questions
Is it better to sell or refinance if I have a low mortgage rate?
If you want to stay, keeping your low-rate first mortgage and adding a HELOC or home equity loan is often worth comparing first, because you only pay a newer rate on the amount you borrow. If you need to move, selling or keeping the home as a rental may still make more sense. Compare the full monthly cost of each option.
Can I keep my current home as a rental and still buy a new one?
Often, yes, if you can qualify with both payments. Projected rent from the home you're leaving may help you qualify under certain guidelines, especially with a signed lease. You'll need enough cash for the new down payment, closing costs and reserves.
Do I pay taxes when I sell my house?
Under current federal rules, many homeowners who lived in the home for at least two of the last five years can exclude up to $250,000 of gain, or $500,000 if married filing jointly. Rules can change and exceptions apply, so check with a tax professional before you sell.
Will my property taxes change if I rent out my South Carolina home?
Usually, yes. South Carolina's 4% assessment ratio is only for a primary residence. A rental is generally assessed at 6%, which can raise the tax bill noticeably.
Should I use a HELOC or a cash-out refinance to renovate?
If your current rate is low, a HELOC or home equity loan often makes sense because you keep your first mortgage. If your rate is already close to today's rates or you need a larger amount, a cash-out refinance may be simpler. A renovation loan is another option for larger projects.
How do I know how much equity I have?
Your equity is your home's current market value minus what you owe. An appraisal or a comparative market analysis from a local agent gives the best estimate. I can help you estimate it and show what you'd net from a sale.
