Almost every second-home buyer I meet on the Grand Strand describes the plan the same way: we'll use it a few weeks a year, and rent it out the rest of the time to help cover the costs.
That sentence sounds like one plan. It's actually three separate legal questions with three different answers — one from your lender, one from the IRS, and one from Horry County — and they don't always agree with each other. Getting the sequence right before you buy is worth real money. Getting it wrong can mean a loan you don't qualify for, a tax bill you didn't model, or a rental you're not allowed to operate.
This article is about the personal-use second home. If the property is primarily an income vehicle, my investment property guide is the one you want. And for the transaction itself, start with the complete guide to buying a home in Myrtle Beach.
Your Lender Has a Definition, and It's Stricter Than You Think
This is the part that surprises Grand Strand buyers most, because it collides directly with how a lot of oceanfront inventory here is actually operated.
Fannie Mae's Selling Guide, B2-1.1-01, Occupancy Types, sets out what a second home has to be:
| Second home requirement | What it means on this coast |
|---|---|
| Must be occupied by the borrower for some portion of the year | You have to actually use it |
| Restricted to one-unit dwellings | A duplex doesn't qualify as a second home |
| Must be suitable for year-round occupancy | Seasonal-only construction is a problem |
| The borrower must have exclusive control over the property | You decide who's in it and when |
| Must not be rental property or a timeshare arrangement | |
| Cannot be subject to any agreements that give a management firm control over the occupancy of the property | This is the one. A building-run rental pool or a management agreement that controls the calendar can disqualify second-home treatment |
There is a narrow accommodation on rental income: the guide states that if the lender identifies rental income from the property, "the loan is eligible for delivery as a second home as long as the income is not used for qualifying purposes, and all other requirements for second homes are met (including the occupancy requirement above)."
Read that carefully. Some rental activity doesn't automatically break second-home status — but you can't use the income to qualify, and the exclusive-control and no-management-firm conditions still have to hold.
Fannie Mae also notes that "an LLPA applies to certain loans secured by second homes" — a loan-level price adjustment on top of any other pricing adjustments — and that second-home loans generally must be underwritten in DU with an Approve/Eligible recommendation. An investment property carries its own LLPA and is defined simply as a property "owned but not occupied by the borrower."
The practical takeaway: if the unit you love comes with a mandatory on-site rental program, ask your lender in writing whether it can still be financed as a second home. Many oceanfront condo buildings here operate exactly that way, and the answer changes both your rate and your down payment.
The IRS Has a Different Definition, and It Turns on 14 Days
The tax code doesn't care what your lender called it. It cares how many days you personally used it.
Per IRS Publication 527, "You use a dwelling unit as a home during the tax year if you use it for personal purposes more than the greater of: 14 days, or 10% of the total days it is rented to others at a fair rental price."
That single test sorts your property into one of three tax treatments:
| Situation | Treatment per Pub 527 |
|---|---|
| Used as a home, rented fewer than 15 days | "You aren't required to report the rental income and rental expenses from this activity." Mortgage interest, property taxes, and qualified casualty losses are reported as normally allowed on Schedule A. |
| Used as a home, rented 15 days or more | Include all rental income, and divide expenses between rental and personal use. Expenses for personal use aren't deductible as rental expenses; a net loss triggers a limitation, calculated on the publication's Worksheet 5-1. |
| Not used as a home | Different rules apply — see the publication |
The first row is the one worth knowing about. If you rent your Grand Strand place out for fourteen days or fewer in the year — Memorial Day week, a golf tournament, Bike Week — the publication says you don't report that income at all. It's a genuinely favorable rule that a lot of second-home owners never learn about.
What counts as a "day of personal use" is broader than you'd guess
Publication 527 defines a day of personal use as any day the unit is used by:
- You, or any other person who owns an interest in it (with a narrow shared-equity exception)
- A member of your family, or the family of any other owner — spouse, siblings and half siblings, ancestors, and lineal descendants — unless they use it as their main home and pay a fair rental price
- Anyone under an arrangement that lets you use some other dwelling unit — a swap
- Anyone at less than a fair rental price
The publication's own example is a beach condo: two co-owners, one uses it for two weeks and the other not at all — "both of you are considered to have used the unit for personal purposes during those 2 weeks."
And a trap worth flagging: "If a dwelling unit is used for personal purposes on a day it is rented at a fair rental price, don't count that day as a day of rental use… Instead, count it as a day of personal use."
Letting your brother-in-law stay for a long weekend at cost is a personal-use day. So is donating a week to a charity auction, under the publication's donation rule. If your plan depends on staying under a threshold, count carefully and keep records — and take this to a CPA rather than to a spreadsheet.
Horry County Has a Third Definition, and It Costs the Most
South Carolina assesses owner-occupied legal residences at a 4% ratio and everything else — including a second home you don't claim as your legal residence — at 6%.
That difference is the largest single recurring cost gap between a primary residence and a vacation home here, and it isn't just the ratio: the school operating credit that comes with 4% treatment doesn't come with 6%. I've written the whole mechanism out rather than repeat it — see the 4% vs 6% assessment ratio and the school operating credit — why 4% saves more than it looks.
Two more from that article that specifically matter to second-home buyers:
- The 15% cap does not protect you the way people assume when a property changes hands. Here's why.
- There's a 25% ATI exemption on 6% property worth understanding before you budget. How it works.
Do not budget your second home from the seller's current tax bill. If they were claiming 4% and you won't, the number changes.
Before You Assume You Can Rent It
Short-term rental legality on the Grand Strand is municipality-specific, and it changes. Myrtle Beach, North Myrtle Beach, Surfside Beach, and unincorporated Horry County are separate jurisdictions with separate rules, and a property's HOA or condo regime can restrict rentals further regardless of what the municipality allows.
So the honest advice is procedural, not a blanket answer: verify current rules with the specific municipality and with the HOA before you buy, in writing, for the specific address. My investment guide covers doing that properly in confirm short-term rental legality before you fall in love with a listing, and the tax layers on rental income covers what applies once you do rent.
If the property is a condo, the regime's rules are their own project — minimum lease terms, guest registration, rental caps, and whether an on-site program is mandatory. Understand rental restrictions before you assume you can rent it out.
Notice how these three constraints interact: the municipality may permit short-term rental, the HOA may require you to use the building's program, and that program's control over occupancy may be exactly what disqualifies your second-home financing. All three need to be answered together, before the offer.
Owning It From Somewhere Else
The part nobody puts in a brochure: a house you're not in is still a house.
Someone has to be here. A key holder, a property manager, or a neighbor you trust. Storm shutters don't close themselves, and an HVAC failure in August in an empty coastal house is a mold claim.
Insurance is different, and it's a two-policy question. Wind and hail is frequently written separately on this coast with its own premium and deductible — wind can be excluded here, and only here. Ask your carrier specifically how a second home, and any rental activity at all, affects the policy. Occupancy matters to insurers as much as it does to lenders.
Flood depends on the mapped zone, and the answer is definite for any given address. How to look up a specific address here.
Hurricane season is a plan, not a worry. Decide before June who closes up the house, who checks on it afterward, and what your deductible actually is.
If it's oceanfront, the state has a say in what you can build and rebuild. The baseline and setback line under the Beachfront Management Act govern additions, pools, decks, and post-storm reconstruction. What to look for when buying a home near the beach.
And your closing still happens here. South Carolina requires attorney supervision of closings per SC Bar Ethics Advisory Opinion 05-16 — though the same opinion confirms "there is no legal requirement that a client attend the closing," and permits a closing by mail when arranged properly. Out-of-state second-home buyers do this routinely; set it up in advance.
The Order I'd Do This In
- Decide honestly how you'll use it. Weeks per year, and whether renting is a nice-to-have or load-bearing for the budget. Everything below depends on this answer.
- Take that answer to a lender and ask whether it finances as a second home or an investment property, and what each costs in rate and down payment.
- Take it to a CPA and ask what the 14-day rule means for your specific plan.
- Verify short-term rental rules with the municipality and the HOA, in writing, for the specific address.
- Price the taxes at 6%, not from the seller's bill.
- Get wind and flood quotes during due diligence, and tell the carrier it's a second home.
- Pick your area for how you'll actually use it — best places to live on the Grand Strand works just as well for choosing where to vacation-own.
- Line up management before closing, not after the first storm.
Frequently Asked Questions
What's the difference between a second home and an investment property to a lender? Occupancy and control. Fannie Mae requires a second home to be occupied by the borrower for some portion of the year, restricted to one unit, suitable for year-round occupancy, under the borrower's exclusive control, not rental property or a timeshare, and not subject to agreements giving a management firm control over occupancy. An investment property is defined as one "owned but not occupied by the borrower." Both carry loan-level price adjustments.
Can I rent out my second home at all? Possibly, subject to three separate answers: your loan, the municipality, and the HOA. On the loan side, Fannie Mae's guide allows delivery as a second home where rental income exists as long as that income isn't used for qualifying and all other second-home requirements are met — the management-firm-control condition being the one that most often fails on this coast.
What is the 14-day rule? Publication 527: you use a dwelling as a home if your personal use exceeds the greater of 14 days or 10% of the days it's rented at fair rental price. Separately, if you use it as a home and rent it fewer than 15 days in the year, the publication says you aren't required to report that rental income or those expenses.
Do my kids staying there count as personal use? Yes. Pub 527 counts use by a family member — spouse, siblings and half siblings, ancestors, lineal descendants — as personal use, unless they use it as their main home and pay a fair rental price. Use by any co-owner counts too, even if you weren't there.
Will my property taxes be higher than the seller's? Very possibly. South Carolina's 4% legal residence ratio applies to an owner-occupied primary home you apply for; a second home is assessed at 6%, without the school operating credit. Model it at 6% before you write the offer.
Should I buy a condo or a house as a second home? It depends on how much you want to manage from a distance and how much rental flexibility you need. A condo hands off exterior maintenance and hurricane prep but adds regime rules, master insurance, reserves, and possibly a mandatory rental program that affects your financing. The condo guide covers what to request before you're under contract. Note also that Fannie Mae restricts second homes to one-unit dwellings.
Can I close remotely? Generally yes, with arrangement. EAO 05-16 confirms no legal requirement that the client attend, and permits closings by mail under conditions. Set it up with the closing attorney and lender well in advance rather than the week of.
Is a second home a good investment? That's a different question, and it deserves the other article. Ownership economics driven by personal use and ownership economics driven by rental income are not the same analysis — see is Myrtle Beach a good place to buy an investment property.
Let's Figure Out Which One You're Buying
Nearly every problem I see with second homes on this coast traces back to the same thing: the buyer's plan for the property and the paperwork's definition of the property never got reconciled before closing.
That reconciliation takes one conversation. Get in touch and tell me how you'd actually use the place — I'll tell you which questions to put to a lender, a CPA, and the HOA, and in what order. My resources page lists the lenders, closing attorneys, and inspectors I work with, and you can browse current listings whenever you'd like.
One note specific to this topic: the personal-use rules above are a summary of Publication 527's tests, not tax advice for your situation. How they apply to you depends on facts a CPA needs to see — take the plan to one before you count on a particular outcome.
