What We Talk About

• Bring dust sample kits (ERMI-style, e.g. Immunolytics) on every showing to test surfaces before making an offer.
• Learn visual red flags: warped floorboards, stained ceilings/corners, bathroom tile growth, and stucco type/installation quality.
• Keep a trusted mold inspector on call to do informal walkthroughs before an offer is made.
• Ask sellers pointed questions (dishwasher leaks, shower leaks, etc.); most were surprisingly honest.
• She toured 40+ homes; about 80% had significant mold, even in Colorado's dry climate and in expensive, newer homes.
• Her real question wasn't "is there mold" but "where is it, how fixable, and what will it cost."
• One stucco issue quoted at $250,000+ was a dealbreaker; minor sink/window-well leaks were manageable and budgeted in.
• She went under contract five times, backing out four times after formal inspections revealed major issues.
• Deal-breakers: foundational problems, roof/siding/stucco-wide water intrusion, and oddities like an indoor jacuzzi, versus minor, containable issues like a single leaky sink.
• Sellers sometimes pushed back hard on repair-cost requests, so having a knowledgeable realtor was essential.
• New homes aren't automatically safer: poor drywall/tile installation and off-gassing (formaldehyde, granite) are common, while very old homes carry decades of leak history.
• Her "sweet spot": homes roughly 8 to 15 years old.
• Crawl spaces and long-term single-owners with strong maintenance records are strong positive signals.
• Filing a legitimate mold claim on a past condo made it harder to get new homeowners insurance.
• Testing approach: dust (ERMI-style) plus air samples plus bulk/swab samples on visible growth; toilets and wax seals are common failure points worth replacing preemptively.
• In Colorado, buyers can exit contracts via "inspection objection" without disclosing mold specifically; she chose whether to share findings with sellers as a courtesy.
• Basements/window wells need proper stone (not mulch) and drainage to prevent water intrusion.
• Post-purchase upgrades: whole-home water filtration, Moen Flo smart shutoff with leak sensors at every fixture, and multiple air filtration units.
• Her advice: budget and stage fixes over time (water/roof/siding first) rather than trying to remediate everything at once.
