It's more the stuff that can really snowball and cost
After years of walking through homes that promised more than they could deliver, experienced house flipper Theresa Vanderstar has arrived at a quiet but hard-won wisdom: the most important decision in renovation is often the one made at the threshold, before a single dollar is spent. Structural decay — sinking foundations, shifting frames, walls mapped with cracks — represents not just a repair challenge but an unknowable financial abyss, and she has learned to let those houses go. In a field that rewards optimism, she has found that discipline and restraint are the more durable virtues.
- Vanderstar walks into a house and her body knows before her mind does — tilting floors, misaligned frames, and spider-webbed cracks are the language of a property that will consume far more than it returns.
- Structural problems are uniquely dangerous because they don't reveal their full cost upfront — they unfold slowly, multiplying through engineering reports, hidden damage, and budget-devouring surprises.
- Cosmetic renovations and even selective wall removal remain firmly in her comfort zone, because they offer the one thing structural repairs cannot: a predictable timeline and a controllable budget.
- After five years of living inside unfinished homes, her appetite for raw potential has been quietly replaced by something more urgent — the desire to finish, to settle, to actually inhabit what she builds.
- The maturity she has developed reframes walking away not as failure but as the sharpest tool in a flipper's kit — knowing which risks to refuse is what separates a sustainable career from a costly lesson.
Theresa Vanderstar stepped into the house and felt it before she could name it. The floors weren't level. Cracks ran across the walls in branching patterns. The doorframes didn't align with the windows. Years of renovation work had sharpened her instincts, and those instincts said no.
For Vanderstar, structural problems occupy a category of their own. A sinking foundation isn't a single repair — it's an investigation, a series of engineering assessments, and a cascade of costs that rarely stop where you expect them to. The unpredictability is the problem. "It's more the stuff that can really snowball and cost," she says. That uncertainty is the line she won't cross.
What she will take on is substantial. Cosmetic overhauls, outdated layouts, even removing walls to reconfigure a space — these are projects she approaches with confidence. The distinction isn't the scale of the labor; it's the degree of control. Painting and fixture replacement come with estimable timelines and costs. Structural failures do not. She draws a careful line between hiring someone to install a beam — manageable, bounded — and committing to repairs that reveal new problems with every layer removed.
Vanderstar and her husband have been living inside a renovation of their 1980s home for over five years, and that sustained experience has reshaped what she looks for in her next project. The hunger for a property with potential hasn't vanished, but it has been tempered by something more grounded: the wish to live in a completed home again. She's no longer chasing every opportunity — she's chasing the right kind of work.
That shift marks a deeper evolution in how she thinks about the business. Early on, almost any house with salvageable bones looks like a chance worth taking. But after years of cost overruns, half-finished rooms, and managed surprises, the math changes. Knowing when to walk away becomes as valuable as knowing when to commit — and for Vanderstar, the smartest investment is sometimes the one she never makes.
Theresa Vanderstar walked through the house and felt it immediately—something was wrong. The floors tilted beneath her feet. Cracks spider-webbed across the walls. The doorframes sat at angles that didn't match the windows. After years of buying and renovating homes, she had learned to trust that instinct. She wouldn't touch this one.
Vanderstar has spent enough time inside renovation projects to know the difference between a manageable problem and a trap. Structural issues—sinking foundations, shifting frames, widespread cracking—are the kind of problems that don't announce themselves cleanly. They hide costs. They multiply. A foundation that's settling in one corner doesn't just need fixing; it needs investigation, engineering reports, and repairs that can consume a budget faster than anyone planned. "It's more the stuff that can really snowball and cost," she explains. That's the line she won't cross.
But she isn't afraid of work. Cosmetic updates, outdated floor plans, even removing walls—those are projects she'll take on. The difference isn't the amount of labor involved. It's control. When you're painting, replacing fixtures, or reconfiguring a layout, you know roughly what you're getting into. You can plan the timeline. You can estimate the expense. Structural problems don't offer that courtesy. They reveal themselves slowly, often after you've already committed money and time. "Even if we had to hire someone to come, like, put in a beam or something, we would do that," she says, drawing a distinction between manageable structural work and the kind that spirals into unknowns.
Vanderstar and her husband are currently living through a renovation of their 1980s home—and they've been living through renovations for over five years. That experience has changed how she thinks about her next project. The appeal of a fixer-upper with potential hasn't disappeared, but it's been tempered by something more practical: the desire to actually live in a finished home again. She's no longer just hunting for properties that need work. She's hunting for the right kind of work—the kind she can control, complete, and move on from.
That shift reflects a maturity in how she approaches house flipping. Early in a renovation career, every property with bones worth saving looks like an opportunity. But after years of living in half-finished spaces, watching costs climb, and managing surprises, the calculus changes. Knowing when to walk away becomes as important as knowing when to commit. For Vanderstar, that means passing on homes where the foundation is failing, the frame is shifting, or the walls are telling a story of structural stress. It means saying no to potential when the risk is too high. And it means recognizing that sometimes the smartest investment decision is the one you don't make.

It's more the stuff that can really snowball and cost— Theresa Vanderstar, on why structural issues are too risky
The Hearth Conversation Another angle on the story
You've turned down homes that other flippers might see as opportunities. What's the moment you realize a property has crossed from "fixable" into "no"?
It's usually physical. You walk in and your body tells you something's off before your mind catches up. Uneven floors, windows that don't sit right in their frames, cracks that aren't just cosmetic. Those things are telling you the house has moved, and moved in ways that are expensive to fix.
But you've hired contractors for structural work before. What's the difference between a beam you'll pay someone to install and a foundation problem you won't touch?
A beam is a known problem with a known solution. A foundation issue is a question mark. You don't know how deep it goes, what caused it, or what else it's damaged. That uncertainty is what kills a project.
After five years of living in renovations, has your tolerance for risk actually decreased?
Completely. When you're living in the space while you're fixing it, you feel every delay, every surprise cost. You start thinking differently about what's worth your time and money.
Do you ever regret walking away from a property?
No. The ones I walked away from would have been disasters. I've seen enough projects spiral to know that my instinct to say no is usually right.
What would make you reconsider a home with structural issues?
Honestly? Nothing. There are too many other homes out there that don't come with that risk. Why would I take it on?
