The Foundation-Stage Spec: Why Relocation Buyers Should Look at Half-Built Houses

When relocation buyers tour a new-construction community in Johnson County, they almost always look at two things: the finished specs with staging furniture, and the empty lots where they could start from scratch. The houses in between, the ones that are a poured foundation or a bare frame with a builder's sign out front, get a glance from the car window and nothing more.

I think that's a mistake, and I've come to believe it's the biggest one relocation buyers make on the new-construction side. Yesterday I published a full guide on choosing between a spec home and a to-be-built contract, and in it I called the early-stage spec "the middle path." This post is the longer version of that argument, because I recommend it more often than anything else to buyers who have a firm move date and also have opinions about their kitchen.

What a foundation-stage spec actually is

A spec home is a house the builder started without a buyer. The builder chose the lot, the plan, the elevation, and, depending on how far along it is, some or all of the finishes. A foundation-stage spec is one where the builder has poured the basement and slab, sometimes framed the first floor, and is now carrying the construction loan while waiting for a buyer.

Production and semi-custom builders in communities like Sundance Ridge and Mills Farm build these on purpose. Starting a house before it sells keeps crews working between contracts and gives the sales office something concrete to show. In a typical Johnson County phase you'll find one or two of them at any given time, and they turn over faster than most buyers realize, which is part of why they get overlooked.

Why the timeline fits a relocation

A relocation buyer's problem is that the move date is usually set by someone else. A start date, a school year, a lease ending, a house that closes back home. If you sign a to-be-built contract in a production community here, you're generally looking at eight to twelve months from contract to keys, and longer for semi-custom or custom work. I walk through each phase in custom build milestones from contract to keys, and the short version is that the first two or three months of that timeline are spent on design-center selections, permits, and getting a crew scheduled before a shovel touches dirt.

A foundation-stage spec skips all of that. The plan is approved, the permit is pulled, the foundation is cured, and the trades are already sequenced. In my experience the realistic window from contract to closing on a foundation-stage spec in Johnson County is four to six months, and a framed spec at or near drywall is closer to sixty to ninety days. That's the sweet spot for a buyer who's relocating in the spring and needs to be in the house before the school year, or who has a corporate relocation package with a window on temporary housing.

Builder completion dates are still estimates. Weather, inspection scheduling, and trade availability move them. But the estimate on a house that's already out of the ground has a lot less room to slide than one that hasn't started.

You still get a say in the finishes

This is the part that surprises people. On a finished spec, every selection is locked, and if you don't love the countertop you're either living with it or replacing it after closing. On a foundation-stage spec, the exterior and floor plan are fixed, but the interior design-center selections are often still open. Cabinet color, countertops, flooring, tile, lighting packages, sometimes the fireplace surround and the plumbing fixtures.

How much is still open depends on the builder and on how far along the house is. Some builders order cabinets and flooring the week the house is framed; others wait until drywall. Ask on the first visit. The question to use is, "What selections are still open on this house, and when do they close?" The answer tells you exactly where the line is between what you can pick and what you're buying as-is.

If the house is framed but the selections are closed, you're closer to a finished-spec situation with a longer wait, and you should price it that way. That's fine, but know it going in. My post on which builder upgrades are worth it at resale is a useful filter for the choices you do get to make.

You can inspect it the right way

One of the real advantages of a to-be-built over a finished spec is that you can hire your own inspector for a pre-drywall inspection, when framing, plumbing rough-in, electrical, and HVAC ductwork are all visible. Once drywall goes up, most of that is hidden for the life of the house.

A foundation-stage spec gives you that same window. You're under contract before drywall, so you can schedule the inspection at the right moment and actually act on what it finds. On a finished spec, the best you can do is a standard inspection plus a pull of the city's inspection records. Both are worth doing, but neither is the same as having your own inspector in the house with the walls open.

Between the pre-drywall inspection and the final walkthrough, you'll see this house twice at the two stages where a second set of eyes matters most. That's a real benefit, and it's one you can't get on the furnished model at the end of the street.

Price and negotiating room

A finished spec that's been sitting carries the most builder incentives, because every month it sits costs the builder money. A to-be-built carries the fewest, because the builder isn't carrying anything yet. A foundation-stage spec sits in between.

In practice, here's what I see. The builder has already committed capital to the house, so there's some motivation to get it under contract, and that often shows up as a modest price concession or a closing-cost contribution rather than the headline incentives on aged inventory. Those contributions are frequently tied to the builder's lender and title company, and I wrote last week about how to evaluate a preferred-lender incentive so you can tell whether it's actually a good deal.

The other lever is that the lot premium is already baked in. On a to-be-built, you pick the lot and pay whatever premium the builder assigns to it. On a spec, the builder picked the lot, and sometimes it's a lot they were having trouble selling. That can cut either way. A walkout lot backing to trees on a spec is a good find. A flat interior lot next to the mailbox cluster is not, and you shouldn't pay a premium for it just because the house is already started.

Where it doesn't fit

I'm not going to pretend this is the answer for everyone. If you want a specific floor plan the builder hasn't started, or you want structural changes like an extended garage or a different elevation, you need a to-be-built. If you need to close in thirty days, you need a finished spec or a resale, and my post on new construction vs. resale in Johnson County covers that decision.

And if you're relocating from out of state and won't be here to see the house at pre-drywall, you'll need to lean on your agent and your inspector more than a local buyer would. That's part of what I do for relocation clients, and it's something to bring up early. My guide to what a buyer's agent does on a new-construction purchase explains why the builder's sales counselor isn't your representative.

What to ask the builder before you write on one

Every builder handles early-stage specs a little differently, so before you write an offer on one, get these answers in writing:

Which selections are still open, and on what date does each one close? What is the current target completion date, and what does the contract say about delays? Is there a pre-drywall inspection window, and will your own inspector be allowed on site? What incentives apply to this specific house, and are any of them tied to the preferred lender or title company? And finally, why did the builder pick this lot for a spec?

That last question sounds odd, but the answer is often informative. "It's our best walkout lot and we wanted a model-quality house there" is one answer. "It was the last lot in the phase" is another. My guide to builder contract clauses to read before you sign covers the rest of what to look for once you have the paperwork in hand.

The bottom line

If you're relocating to Johnson County with a fixed date, a foundation-stage spec gives you most of what makes new construction appealing, a locked plan, a shorter and more predictable timeline, and a real inspection window, while still leaving you a say in the finishes you'll actually live with. Those houses are easy to drive past. Don't.
