HELOCs and Second Mortgages in Carolina Forest, SC: What Your Equity Can Support

BelleGrove, a Carolina Forest subdivision, flooded in 2015 and flooded again in 2016 under Hurricane Matthew. In 2018, MyHorryNews reported that a drainage project there had been finished the year before. A HELOC is secured by the home, so that history is a fair thing to know before you borrow against the walls and the lot.

If you live in your Carolina Forest home and want to borrow against its equity, the lenders I use will lend up to a combined 75% to 95% of its value, depending on your credit score. A line also has to clear that lender's minimum size to be worth opening. A second mortgage comes behind your first mortgage and leaves it exactly as it is.

I'm Jeff Moran, NMLS #483943, a mortgage broker licensed in South Carolina through C2 Financial Corporation, NMLS #135622, and I have been in the mortgage business since 1996. I'm licensed across South Carolina and work with Carolina Forest clients by phone. My Carolina Forest page covers the community, my Myrtle Beach area page covers Horry County, and the home equity page compares the ways of using equity, including the ones that are not a second mortgage. The terms below are what the sheets of my second-mortgage lenders say, dated May 2026, and I am quoting them, not quoting you a rate.

Reading the room your equity leaves

Lenders measure equity as a combined loan-to-value ratio, or CLTV: your first mortgage balance plus the new line, divided by what the home appraises for. A lender sets a ceiling on that ratio by credit score. Your room is the ceiling times the home's value, minus what you owe.

For the arithmetic, I'll use a price from the market data. The Coastal Carolinas Association of REALTORS calls Carolina Forest area 10B. Its year-to-date single-family median through August 2026 was $475,000, up 8.8% from $436,734 for the same months of 2025, on 626 closed sales. That is 27.2% fewer than a year earlier, per its August 2026 market update. A median is not your home's value, and the appraisal sets that. I'll pair it with a first mortgage balance of $250,000, a round figure I picked.

First lender, primary home, one unit	Ceiling	All loans combined on $475,000	Room for the line
Score 720 or higher	95%	$451,250	$201,250
Score 680 to 719	90%	$427,500	$177,500
Score 660 to 679	80%	$380,000	$130,000
Score 640 to 659	80%	$380,000	$100,000, because the line is capped there

The cap in the last row comes from the sheet itself: at 640 to 659 the maximum line is $100,000, and at 660 to 679 it is $200,000. Above those scores, a line can be $750,000 when the combined ratio is 65% or less and $500,000 above that.

Why the smallest line matters as much as the biggest

The second lender's HELOC starts at a $125,000 line. That changes the same home's answer. On its primary home sheet, a full-documentation line reaches 90% at a score of 760, 85% at 720 and 75% at 680.

Second lender, primary home	Ceiling	All loans combined on $475,000	Room for the line	Clears the $125,000 minimum?
Score 760	90%	$427,500	$177,500	Yes
Score 720	85%	$403,750	$153,750	Yes
Score 680	75%	$356,250	$106,250	No

At 680, the arithmetic leaves $106,250, which is under that lender's minimum line, so on this home that lender would not fit. The first lender, whose lines begin at $25,000, would. That is one reason I price more than one lender before telling you what is possible. A home equity loan, which the second lender's sheet calls a closed-end second, starts at $100,000 and runs 10, 15, 20 or 30 years at a fixed rate. So if you need a smaller amount, the HELOC with the lower minimum is the one that goes there.

Both lenders also ask for reserves, which is money you hold after closing. The first lender's sheet requires none on a primary home with a score of 680 or higher and a line of $200,000 or less. The second lender asks for 6 months of full payments on both mortgages.

The appraisal is where an inland community gets tested

The value comes from an appraisal or an automated valuation, and the sheets treat the two differently. The first lender's sheet accepts an automated valuation for a line of $400,000 or less and asks for a full appraisal above that. It also has a declining-market table. If the valuation shows no decline, a one-unit primary home can go to 95%. If it shows a decline of up to 1%, the ceiling is 85%, and if it shows more than 10%, it is 65%. A valuation that does not report the market percentage at all is capped at 65%.

Carolina Forest's median moved up in 2026, as above, but I would not plan a loan around prices rising. The sheet also says a home bought less than 6 months ago uses the lower of the purchase price or the appraisal. The second lender asks that the home not have been listed for sale in the last 6 months.

Your association and the documents behind it

The first lender's sheet names PUDs and townhouses as eligible property types, and it requires a condo to be warrantable, which is the agency term for a project that meets Fannie Mae's rules. I found no public source for any Carolina Forest community's dues, so I will not guess at them. Please ask your association for its budget and covenants and give me the monthly dues, because they count in your debt ratio.

The first lender's sheet caps your housing and total debt ratios at 38% and 43% below a score of 720, and at 43% and 45% at 720 and above. The second lender caps the total at 45% below a score of 700 and 50% at 700 or higher.

What an inland address changes, and what it does not

Carolina Forest is in unincorporated Horry County, so your tax bill has no town line, and a second mortgage does not change your tax district. The first lender requires title insurance when the line is above $250,000, and a property report at or below that.

If the home is in FEMA's high-risk flood zone, flood insurance is required, and one of my lenders is a credit union that federal rules bar from making a loan on a home in that zone without it. I do not rely on a community-wide statement either way. Your address's zone is a lookup on Horry County's Flood Map App, and I run the premium into your payment before you commit.

Fees, the rate and what is variable

On the first lender's sheet, a HELOC rate is the Prime Rate plus a margin set by your score, your combined ratio, the line size and the occupancy, with a floor of 4.95% and a lifetime cap of 18%. It adjusts by no more than 2% a year and has no prepayment penalty. Fees include a $495 origination fee and a $100 processing fee, debited from the line at closing. The draw period is 10 years, interest only, then repayment over the following two decades.

The state's deed recording fee applies to deeds, and a second mortgage is not one. My South Carolina page covers attorney closings, and refinancing or a cash-out refinance is the route if replacing your first mortgage fits better.

What I would ask you for first

Please send your most recent first mortgage statement, all pages, even if the last page is intentionally left blank, plus your homeowners declarations page and your association's contact information. Getting pre-approved in South Carolina explains the paperwork for a purchase. For a line, I will tell you which lender fits your score, your balance and the size of the line you want. Home equity lines are not priced in the Rate & Best Fit tool on this site, so the next step is a call to me.

Nothing on this page is a loan approval, a denial or a commitment to lend, and it is not tax advice. Each lender sets its own terms and can change them, and the appraisal and your income and credit decide where you land under the ceilings above.

Common questions

How much can I borrow against my Carolina Forest home?

It depends on the lender's ceiling for your credit score, your home's appraised value and your first mortgage balance. Multiply the value by the ceiling and subtract what you owe. On a primary home, the first lender's sheet allows 95% at a score of 720 or higher, 90% at 680 to 719 and 80% at 640 to 679.

Is there a minimum HELOC size?

Yes, and it differs by lender. The first lender's lines begin lower than the second lender's, which starts at a higher minimum line. When your equity leaves less room than a lender's minimum, that lender is not the fit.

Does a HELOC change my first mortgage?

No. A second mortgage is a separate loan behind your first mortgage, with its own rate and payment, and your first mortgage keeps its rate and terms.

Does a flood zone affect a HELOC in Carolina Forest?

It can. If the home is in a high-risk flood zone, flood insurance is required, and a credit union lender cannot lend on it without that coverage. The County's map shows the zone for your address.

Do I apply through the rate tool on this site?

Not for a home equity line. Those are not priced there, so a call to me is the first step, and I work through your scenario with you.
