What to Do After a Home Inspection, and When to Walk Away

I told a client to walk away from a house in downtown Bozeman this year. To this day, neither one of us knows everything that was wrong with it.

It was one of those older places just off the historic part of town, added onto and reworked for close to a hundred years. Almost every one of those additions had brought a foundation of its own. We sent an inspector underneath, and some of those newer foundations had ended up carrying weight the original was never built to hold. A crack in a wall I see all the time, and I don't lose much sleep over it. This one had been handed a job nobody designed the house to do.

We spent weeks on that house. Somewhere in the middle of it, the seller did something that told me more than the inspection report did. There's also one situation where I'll tell a buyer to walk even when the seller says yes to every repair on the list.

Rather listen than read? I walk through the whole thing on camera: The Downtown Bozeman House I Told a Buyer to Walk Away From.

The short version

Sort the report into three groups before you negotiate: items that only cost money, items that cost a season of your life, and items nobody can price until walls come open. The third group usually can't be negotiated at all.

How the seller responds to the report is the most underrated signal in the transaction. How hard somebody pushes on one specific item tends to tell you which items they already knew about.

Decide your walk-away line before the report lands, while it's still theoretical and you haven't pictured your furniture in the rooms.

What should you do after a home inspection?

Sort the findings rather than treating them as one list. Separate what simply costs money from what costs contractors and months. Keep both apart from anything nobody can price without opening up walls. Then weigh the result against your own appetite for projects. The same house can be a good buy for one person and a two-year obligation for another. Set your walk-away line before you start asking for repairs.

Well and septic: the test nobody ran

The most expensive surprises in this valley tend to sit in the ground rather than in the house. Out here that starts with water. Arriving from somewhere on city utilities, you'll feel this one. A well and a septic system belong to you now in a way a water bill never did.

On the well side, a real test means somebody runs it hard for a couple of hours and measures what it puts out. That number either supports a household or it doesn't. Timing is what makes it tricky. A well can look fine in June with snowmelt still feeding everything, then behave like a different well by the middle of a dry September. When the flow comes back short, you're deepening what's there or drilling new.

Septic runs the same way. I've seen tanks come back cracked and near the end of their life. I've also seen drain fields that looked fine on paper and on the surface, then turned out to be choked with roots underneath. That's what happens when somebody plants a nice row of cottonwoods over a field forty years ago. Nobody thinks about it again. A drain field replacement means a new permit, a new design, and equipment sitting in your yard for a while. Gallatin County also tightened its septic rules in 2025, so lots draining toward impaired streams now need a nitrogen-reducing system that runs about $20,000 on top of a standard one.

Here's the red flag on both. Where the report gives you one line about the well or the septic with no test behind it, nobody has checked. Confirm that before you sign anything.

Crawl space and attic moisture

Inside the house, moisture is what I see most often in this valley, and it lives in the crawl space and the attic. Why those two places? We get cold. Snow sits for six months. Then warm stretches arrive mid-winter, everything melts, and it refreezes on top of itself. Put that against a crawl space with old insulation and not much air moving through it. Those are the conditions mold likes. Attics do the same thing where the ventilation was never quite right and warm air has been sitting against a cold roof deck for decades.

Let me be careful here, because mold sounds like a bigger word than it usually deserves. We see it constantly and it's fixable. Spraying it and calling it done is where people get hurt. The conditions that grew it will still be there when the crew drives away. Then it comes back and you've paid twice.

Doing it properly usually means pulling the old insulation out and replacing it, adding real ventilation, and getting air moving through the space. Some houses need a dehumidifier down there permanently. So here's the red flag. Watch for a bid that treats mold as a cleaning job with nothing about insulation or ventilation in it. That one came from somebody who will be long gone before you learn it didn't hold.

The work nobody wrote down

Back to that downtown house. It's the clearest version of the third thing to watch for, which isn't a defect at all. A hundred-year-old home in Bozeman has almost always been changed. Somebody enclosed a porch in the forties. Somebody put a bedroom over the garage in the seventies. Somebody opened up a wall in 2009 because that was the look everybody wanted that year.

Each of those decisions got made by a different person on a different budget. The city and the county were enforcing something different at the time, too. A good share of it was never permitted at all. So when the inspector found those foundations stacked underneath, the foundations were only part of what worried us. The real problem was that we had no way to learn what else had been done in there. The engineers said they'd have to open up foundation walls to speak with confidence. No seller allows that on a house you don't own yet.

In a lot of ways we knew less about that house after all those weeks than we thought we knew in the first one. The red flag is simple. Stand on the sidewalk and count the additions from the front. You're buying what you can see, plus some amount of work nobody ever wrote down.

How I sort a report before anybody negotiates

Say eleven things come back. What do you do with all of it? Stop treating it as one list.

Some of what's on there only costs money. A water heater or a furnace lands in that group nearly every time. You get a number, you ask for it or you absorb it, and it's finished.

The second group costs contractors and time and probably a season of your life. A drain field or a crawl space belongs there. The money is only part of what you're agreeing to.

Then there's the group that's simply unknown. The honest answer is that nobody can tell you what's in there until walls come open. That last group is what decides things, and buyers skip past it fastest.

The sorting matters for one reason. Say you've done projects before, you have the time, and you enjoy some of it. A long list of ordinary work might make that a great house at the right price. That same house, when you're deep in a career without a free weekend until next spring, will run your life for two years. Sort it that way before negotiations start. The three groups get handled completely differently, and the third one usually can't be negotiated at all.

What the seller does when the report lands

Here's the part I promised, and I'd call it the most underrated signal in a transaction. Watch what the seller does when the report comes in.

Some of them acknowledge it. They hand over what they have. They'll tell you when the roof went on, what they've been meaning to get to, and offer something reasonable. Those people generally aren't hiding anything.

Then there's the other version. You ask for a sewer scope and they won't allow it. Somebody tells you the water stain happened years ago and got handled, with nothing to back it up. You bring a real number from a real contractor and hear that the inspector is being dramatic. Anybody who has lived in a house for fifteen years knows things about it no inspector finds in three hours. How hard they push on one specific item tends to tell you which items they already knew about.

Credits, and how buyers talk themselves into a house

Where a seller holds firm is where good buyers talk themselves into things, so watch yourself here.

Say the seller says no on the drain field, so you take a credit instead. Then the work gets priced and the credit covers half of what you need. The credit already feels like yours, so you make up the difference. Then something else surfaces and you tell yourself you'll handle that one too.

Nobody makes that decision all at once. It happens a little at a time across a week and a half. At the end you've bought a house you never agreed to buy. Draw your line before the report ever comes back, while it's all still theoretical.

Why I'll still say walk when the seller agrees to everything

There are houses where the seller says yes to every item and I'll still tell somebody to walk. It happens when the repair list was never the real issue.

What bothers me in that situation is simpler. Every item gets handled, and the thing that worried me most is still sitting there untouched. A list of agreed repairs can look like a resolution while answering none of the question you had.

What owning a home here keeps asking of you

Think past the inspection to the day it closes and the house is yours. Ownership in this valley keeps asking things of you no matter what the report said. Most people underestimate this part, and a lot of it is simply what owning a home here involves.

Hail damages roofs regularly. Freeze and thaw cycles work on shingles all winter, and ice damming backs water up underneath them into places you won't hear about until spring. Drainage is the other one, and I'd stay on top of it forever. Snow piled against your foundation all winter melts in March, and then it rains on top of that. Where all of that water goes is either something you handled or something you find out about later.

So even on a house that inspected clean, watch the roof and keep water moving away from the foundation. Go back into the crawl space once in a while too, so you know what's happening down there. I'm not raising this to talk you out of an older home. The people who are happiest out here are the ones who went in knowing what to expect.

Where my client landed

She walked away, and I think it was the right call. It was hers rather than mine. Nobody could tell her when or whether that house would fail, and the engineers wouldn't call it fine either. What I could tell her was this. We'd spent weeks and real money, and we still had a list nobody was going to be able to answer.

That house is one of the five in the five Bozeman homes I treat differently, . The structural estimate on it came back at six figures. Worth reading alongside this if you're looking at a century-old place near Main Street.

The ten-year question

This is the question I ask every buyer. Every house here has problems. Mine does, and yours will too. What you're deciding is whether the things you found, plus the things nobody can find, add up to something you're willing to own for the next ten years.

That answer changes depending on who you are. Somebody who has done this kind of work before might look at the same house and still want it. Where it adds up and the work fits your life, buy it and enjoy it. If the answer comes back no, there are other houses coming. I've had far more clients tell me they were glad they waited than the other way around.

Both decisions at once

Every buyer out here is making two decisions at the same time. What they pay, and what they're taking on. The second one is the expensive one to get wrong.

Most of my clients are busy professionals without the time to run a project like that downtown house. They want a move that builds real financial wealth along with a life worth making it for. Planning for both at once is what the Montana Move Method is built around.

After the inspection: quick answers

What should you do after a home inspection?
Sort the findings into three groups rather than one list: items that only cost money, items that cost contractors and months, and items nobody can price without opening up walls. Weigh the result against your own appetite for projects, then set your walk-away line before you start requesting repairs.

Should you walk away after a bad home inspection?
Walking makes sense when the report leaves questions nobody can answer, rather than when the repair list simply runs long. A seller agreeing to every item doesn't resolve anything if the issue that worried you most is still unexplained after the repairs are done.

How do you read a seller's response to an inspection report?
A seller who hands over records, says when the roof went on, and offers something reasonable is usually not hiding anything. Refusing a sewer scope, dismissing a contractor's number, or pushing unusually hard on one specific item tends to point at what they already knew about.

Should you take a repair credit or ask the seller to fix it?
A credit is fine where you know the real cost. The risk is that it covers half the work and you absorb the rest, because the money already feels like yours. Price the repair with a contractor before you accept a number, and decide your limit before the negotiation starts.

Does a home inspection include the well and septic?
A standard home inspection does not test a well or a septic system, and Montana doesn't require either one, so the buyer orders them separately. Ask for a flow test on the well and a pump-out with a camera run on the septic. One line in a report with no test behind it means nobody checked.

How much does a septic drain field replacement cost in Gallatin County?
A replacement requires a new permit, a new design, and heavy equipment on the property. Gallatin County tightened its rules in 2025, so lots draining toward impaired streams now need a nitrogen-reducing system that adds roughly $20,000 over a standard installation.

Is mold in a crawl space a deal breaker?
Crawl space mold is common in this climate and fixable, since freeze-thaw cycles and poor ventilation create the conditions for it. Check the bid. Treating it as a cleaning job, without addressing insulation and ventilation, means it returns and you pay twice.

What should you know about buying a century-old home in Bozeman?
Nearly all of them have been altered repeatedly, often by different owners under different codes, and a good share of that work was never permitted. The larger risk is the undocumented work rather than the defects an inspector finds, since nobody can price it without opening up walls.

How do you decide whether a house is worth the problems?
Ask whether the issues you found, plus the ones nobody can find, add up to something you're willing to own for ten years. The answer depends on your own time and experience. One person's good buy at that price is another person's two-year obligation.

Looking at a report right now?

Book a call with me and send the inspection summary. I'll sort it into the three groups with you. Then I'll tell you which items I'd push on and which I'd absorb. I'll also flag anything in there that reads as a question nobody can answer.
