Fee Build vs. Buying a Finished Spec Home: Where the Margin Sits
A finished spec home has the builder's profit, overhead, and selling costs inside its price. A fee build moves the land, carry, selling costs, and spread to you.
The build vs buy investment property choice comes down to who keeps the spread between cost and market value. When you buy a finished spec home, the builder's profit, overhead, sales costs, and carry are already inside the price. In a fee build, you buy the lot and the house separately, so the land, the carry, the selling costs, and the spread between your all-in cost and market value move to you, along with the risk.
Spec home vs. fee build: two definitions
The U.S. Census Bureau defines a home built for sale, also called speculatively built, as a house built on the builder's land with the intention of selling the house and land. That is a spec home. The builder owns the lot, funds the build, and sets the price when it lists the home.
A fee build reverses the ownership. You own the lot before construction starts and you own the home at the certificate of occupancy. The builder builds under contract using its plans and pricing. Our guide to how a fee build works covers the full process.
Where the margin sits in a finished spec home
The National Association of Home Builders surveys builders on what goes into a sale price. Its Cost of Constructing a Home 2024 study reported an average single-family sale price of $665,298, split this way:
Construction cost: $428,215, or 64.4% of the price.
Finished lot: $91,057, or 13.7%.
Overhead and general expenses: $38,248, or 5.7%.
Sales commission: $18,955, or 2.8%.
Financing cost: $10,220, or 1.5%.
Marketing cost: $5,633, or 0.8%.
Profit: $72,971, or 11.0%.
Read these as national averages, not a Carolinas price list. NAHB received usable responses from 41 builders and says the sample is not designed to represent the average home built in a given year. The point is the structure: in this survey, 21.8% of the average price went to profit, overhead, selling, and financing.
NAHB's economics blog, Eye on Housing, notes that construction cost's share rose from 60.8% in 2022 to 64.4% in 2024, while the finished lot's share fell from 17.8% to 13.7%. Shares shift with the market, so check the date on any cost study you rely on.
What moves to you in a fee build
When you build instead of buy, some of those spec-home line items stop being the builder's and start being yours. Use this list to see which ones:
Land: you buy the lot and own it. Its price, and its carrying cost during the build, are yours.
Construction financing: you fund the build with cash or a construction loan. Interest during construction is your cost.
Selling costs: if you sell, the commission and marketing are your decision and your expense. If you hold or rent, you skip them at the start.
Market risk: the sale price or rent at the end is set by the market, not by you. If it comes in low, the shortfall is yours.
The spread: whatever the home is worth above your all-in cost stays with you, as sale proceeds or as equity in a home you hold.
On a Red Cedar Homes fee build, the house is priced on three lines with the land separate. Line 1 (site work and foundation) and Line 2 (soft costs) are estimates billed at actual cost and trued up within 30 days of the certificate of occupancy. Line 3, the Guaranteed Vertical Price, is fixed at signing and includes Level 2 interiors, a one-year limited warranty, and builder's risk insurance.
Running the build vs buy investment property math
Compare the two on the same plan in the same submarket. Build two numbers:
Buy: the finished home's contract price, plus your closing costs and loan costs.
Build: the lot price, plus Lines 1, 2, and 3, plus change orders, plus construction interest, taxes, and insurance on the lot during the build, plus closing costs on the lot and the loan.
Value: a realistic sale price or rent for the finished home, from recent comparable sales or leases, not a list price you hope to get.
Compare: the gap between value and each all-in cost, and the months your cash is tied up before the home earns anything.
The fee build deal calculator runs the build side with your lot, sale price, and financing. Its results are your own estimate from the numbers you enter. They are not a Red Cedar projection.
Deed fees in South Carolina and North Carolina
Transfer taxes follow the deed, so they land differently on each path. South Carolina's deed recording fee is $1.85 for each $500 of value ($1.30 state plus $0.55 county), and the grantor owes it under Section 12-24-20. North Carolina's excise tax under G.S. 105-228.30 is $1.00 for each $500, paid by the transferor.
Buying a spec home: the builder pays the fee on the full sale price of the house and land.
Fee build: the deed that conveys the lot carries the fee on the lot price. The house is built on land you already own, so no second deed is recorded for it.
Your exit: if you later sell either home, you are the seller, and you pay the fee on your sale price.
Time, inspection, and income
The margin is only one side. A finished home trades it for speed and certainty:
Income timing: a finished spec home can be leased or resold after you close. A fee build earns nothing until the certificate of occupancy, and you carry the lot and loan through construction.
What you can see: you can walk and inspect a finished home before you sign. In a fee build, you approve a plan, an interior level, and a price, and the house is inspected as it is built.
Choice: with a spec home, you take the plan, lot, and finishes the builder chose. In a fee build, you pick the lot, the plan, and the interior level to match your exit.
If you plan to rent, run the rental side with care. Our breakdown of new construction rental property numbers lists the costs to include. Our post on what is included in a new construction price shows what to check on a finished home's contract.
Which path fits
Buying finished tends to fit when you want income soon, cannot carry land and a construction loan, or want to inspect the exact house before you commit. Red Cedar's homes available now show what finished product sells for in its markets.
Building tends to fit when you already own a lot, can fund the carry, want a specific plan on a specific lot, or plan several homes on a schedule. Red Cedar offers fee builds on a Red Cedar lot or on your own lot in Charlotte, Greenville, and Spartanburg, with 11 plans and published vertical prices. You can sell with your agent or Red Cedar's, lease through Red Cedar Homes, or hold.
Frequently asked questions
Is it cheaper to build or buy an investment property?
It depends on the lot, the plan, and the market. A finished spec home includes the builder's profit, overhead, selling, and financing costs in its price. A fee build moves the land, the carry, the selling costs, and the spread to you, along with market risk. Price both paths on the same plan and submarket before deciding.
What is a spec home?
A spec home is a house a builder builds on its own land with the intention of selling the house and land, which is how the Census Bureau defines homes built for sale. The builder sets the price when it lists the home, and you buy it finished or near finished.
How much profit does a builder make on a new home?
NAHB's 2024 cost survey reported average builder profit of 11.0% of the sale price, or $72,971 on an average price of $665,298. That figure is a national average from 41 builders, and NAHB says the sample is not designed to represent the average home built that year.
Can I rent a fee build home instead of selling it?
Yes. You own the finished home, so the exit is yours. On a Red Cedar fee build, you can sell with your own agent or Red Cedar's, lease the home through Red Cedar Homes, or hold it. Plan the exit before you choose the plan and interior level.
