8 Things I Check at Every Showing (Before My Buyers Write an Offer) header image.

Most buyers walk into a home and head straight for the kitchen.

I head for the corners of the ceilings.

Then I check the caulk around the master tub. I open the crawl space. I look at the breaker panel. I run a faucet. Within the first two minutes of a showing, I can usually tell whether a seller has maintained the home or whether they have been quietly ignoring it for eight years and hoping you will not notice.

Here is why that matters in today's market.

The average buyer in the west metro right now is putting 5 to 10 percent down on a home priced between $500,000 and $750,000. That is $25,000 to $75,000 of real money, often money that took years to save. One missed red flag at a showing can wipe out that entire down payment in repairs you never saw coming.

Before any of my buyers write an offer, I walk them through what I am looking for and why. Below are the eight things I check at every single showing.

1. Yellow or brown stain rings on ceilings

Look specifically under bathrooms, near HVAC vents, and where a chimney meets the roofline. Those halos indicate a past or active water leak. Sellers paint over them, but the outline usually remains if you look closely. Bring a flashlight to every ceiling corner.

2. Caulk pulling away from the tub, shower, or kitchen sink

When caulk separates, water has been working its way behind the surface, sometimes for years. Behind that gap is often rotted subfloor or mold. What looks like a $30 tube of caulk is rarely less than $2,500 to repair once you open the wall.

3. A crawl space access that is nailed shut, blocked, or missing a key

That is not normal. When a homeowner cannot or will not provide access, there is usually a reason. Moisture damage, pest activity, rotted joists, and failing foundation piers are common culprits. Always require access before going under contract. No exceptions.

4. Small, patchy paint touch-ups in unexpected locations

A 12-inch square of fresh paint on a closet ceiling. A clean stripe running along a baseboard. A perfect rectangle on the garage wall. These are not coincidences. Ask what was painted, when it was painted, and pay close attention to how the answer lands.

5. Soft spots or visible sag in the subfloor

Walk slowly through every bathroom, laundry room, and kitchen. If the floor flexes under your weight, there is water damage underneath. Repairs start around $3,000 and climb fast. If you can already see the floor dipping, you are not catching it early.

6. Mineral buildup on faucets, showerheads, and the dishwasher inlet

Hard water is hard on everything. Appliances, fixtures, and the water heater all take a beating when mineral deposits go unaddressed. If the buildup is heavy, the water heater is likely running at reduced capacity and may be close to the end of its useful life. A whole-house softener runs $1,500 to $3,500, and water heater replacement typically follows within a couple of years.

7. Drainage problems around the foundation

Standing water against the foundation, downspouts that terminate at the wall, or soil that slopes toward the home rather than away from it are all warning signs. Drainage issues are the leading cause of basement and crawl space moisture in this region, and moisture leads to mold, rot, and pest problems. Correcting grading and adding extensions costs $1,500 to $5,000. Ignoring it costs significantly more.

8. A neglected HVAC system

A rusted outdoor unit, a visibly black air filter, or no service sticker from the past five years all point to mechanical neglect. Budget for replacement within two to four years. A new high-efficiency furnace and central air system, installed, typically runs $10,000 to $18,000 in this market.

What to Do When You Spot These

Most of the items on this list are fixable. Some of them are a reason to walk. The entire point of this exercise is knowing the difference before you write an offer based on good lighting and a staged living room.

If you spot two or more of these on a showing, take photos of each one with the location noted. Bring the list to me so we can factor it into the offer price if you want to move forward. If we proceed, write in an inspection contingency that gives you the right to exit based on inspector findings. And hire an inspector who specializes in older homes, not the least expensive option on Google.

Buyers who skip this process do not save time. They just pay for it later.

If you are shopping in Buffalo, Delano, Rockford, St. Michael, or anywhere in the west metro and want someone who will actually protect your investment at every showing, that is exactly what I am here for.
