A Johnson County agent's guide to choosing between a builder's spec home and a to-be-built contract when your move date, price, and selections all matter.
Almost every relocation buyer I work with hits the same fork in the road about two weeks into their search. They've fallen for a community, they've walked the model, and the on-site salesperson says something like, "We have a spec closing in November, or we can start one for you on lot 42." Then they call me and ask which one is the smart move.
The honest answer is that it depends on three things: how hard your move date is, how much you care about picking finishes, and how much negotiating room you want. This page walks through each so you can answer it for yourself, and so you know what to ask when you're standing in that sales office. If you're still deciding whether new construction is right for you at all, start with new construction vs. resale in Johnson County and come back here.

What a Spec Home Actually Is
A spec home (short for "speculative," and sometimes called an inventory home or quick move-in home) is a house the builder started without a buyer under contract. The builder picked the lot, the plan, the elevation, and every finish, and is carrying the construction loan until someone buys it. In Johnson County you'll see specs at every stage: a foundation with a "coming soon" sign, a framed house at drywall, or a finished home with staging furniture in the great room.
Production and semi-custom builders in communities like Sundance Ridge and Mills Farm build specs deliberately. It keeps their crews working between contracts and gives them something to show buyers who can't picture a house from a floor plan. Custom builders build specs too, but less often and usually at a higher price point. My builders map of Johnson County explains which tier is which.
What To-Be-Built Actually Means
A to-be-built contract means you choose the lot and the plan, make your selections at the design center, and the builder starts construction for you. You're buying a promise and a set of drawings, not a house you can walk through. The builder's contract governs everything from the start date to what happens if lumber prices jump, which is why I wrote a whole page on builder contract clauses to understand before you sign.
The appeal is obvious: it's your house, your finishes, your lot. The cost is time and a certain amount of faith in the builder's schedule.
Timeline: The Real Difference
This is where most decisions actually get made.
A finished spec can close in 30 to 45 days, about the same as a resale. A spec at drywall is typically 60 to 90 days out. A spec at foundation stage is closer to a to-be-built in timing, but you still skip the design-center weeks because the selections are already locked.
A to-be-built in a production community in Johnson County generally runs eight to twelve months from contract to keys, and a semi-custom or custom build can go well past a year. I lay out each phase in custom build milestones from contract to keys. The important thing to know is that builder completion dates are estimates. Weather, inspection scheduling, and trade availability move them, and most contracts give the builder generous room to slide.
If you have a job start date, a lease ending, or a house to sell on a specific timeline, that uncertainty is the whole ballgame. I've had clients rent for six months to wait on a to-be-built and be glad they did. I've also had clients who needed to be in a house before school started in August, and for them a finished spec was the only realistic answer.
Price and Negotiating Room
Here's what surprises people: the spec is often the better deal, and the reason is carrying cost.
Every month a finished spec sits, the builder pays interest on the construction loan, plus taxes and utilities. A spec that's been complete for 60 or 90 days is a spec the builder wants gone, and the lever they pull first is the incentive: closing-cost credits, rate buydowns, or included upgrades. Most of those are tied to using the builder's lender, and I explained what a preferred-lender incentive actually costs you yesterday. The short version: the incentive can be real, but compare Loan Estimates before you assume it is.
To-be-built pricing is firmer. The builder isn't carrying anything yet, the base price is published, and the negotiating usually happens at the margins: a lot premium, a specific upgrade, or the incentive package. What you gain is control over where the money goes. If you'd rather spend on a finished basement than on the builder's choice of quartz, a to-be-built lets you make that call, and my post on which builder upgrades hold value at resale is worth reading before you sit down at the design center.
One more price note. A spec was designed to appeal to the widest possible buyer, so it usually has the safe, neutral package. That's not a flaw, but it's why specs can feel a little interchangeable, and it's a reason some buyers are willing to wait.
Selections and What You Can Still Change
On a finished spec: nothing structural, and usually nothing at all. You're buying it as it stands.
On a spec at drywall: sometimes paint, flooring, lighting, and hardware, if the builder hasn't ordered them yet. Ask. Some builders will let you make late changes for a fee; some won't touch the schedule.
On a spec at foundation: often a meaningful set of interior selections, since the exterior and floor plan are fixed but the design-center choices may still be open.
On a to-be-built: everything the plan allows, within the builder's menu. Production builders have a defined selections list. Semi-custom builders let you make structural changes early. Custom builders let you change nearly anything, at the cost of time and change-order fees.
Inspections Work Differently
This one matters more than people expect. On a to-be-built, you can schedule a pre-drywall inspection and see the framing, plumbing, and electrical before they're covered. On a finished spec, that window has closed. You still get a full inspection and a final walkthrough with a punch list, and new homes in Johnson County are inspected by the city at each stage, but you're trusting work you can't see.
That's not a reason to avoid specs. It is a reason to hire your own inspector on a spec rather than relying on the builder's walkthrough, and to ask for the city inspection records, which the builder should have.
Which One Fits Your Situation
Choose the spec if your move date is fixed within the next four months, you want the most negotiating leverage, or you're a buyer who would rather see the actual house than imagine it from a plan. It's also the right call in a market like ours, where resale inventory is tight and a finished new home may be the only move-in-ready option in your price range in the community you want.
Choose to-be-built if you can wait eight to twelve months, you care about specific finishes or a specific lot, or you want the pre-drywall inspection and the ability to control where the upgrade dollars go.
And consider the early-stage spec as the middle path. A foundation-stage spec in the right community gives you a locked plan and elevation, a shorter timeline, and often a partial say in the interior. It's the option I find myself recommending most often to relocation buyers who have a date but also have opinions.
Questions to Ask Before You Sign Either Way
For a spec: How long has it been complete? What's included in the incentive, and is it conditioned on the builder's lender? Which selections, if any, are still open? Can I see the city inspection records?
For a to-be-built: What's the estimated completion date, and what does the contract say about delays? How are cost increases handled? When are selections due, and what does a change order cost after that? What's the pre-drywall inspection policy?
For both: Who represents me in this transaction? The on-site salesperson works for the builder. That's not sinister, it's just their job, and it's why buyers still need their own agent on new construction. Bringing me in before you register with a community costs you nothing and puts someone on your side of the table.
If you're weighing a spec against a start in any Johnson County community, reach out and tell me your move date. That one detail usually narrows the answer faster than anything else.
