  1. 1.Lead paint

    Federal rule

    Federal law requires a lead-paint disclosure for most housing built before 1978. Worth checking for this era.

    Pre-1978: the federal lead-paint disclosure applies to most housing built before 1978.

    How to spot it. Start with the year built. Ask for the disclosure, the EPA/HUD pamphlet, and any report the seller already has. Peeling paint is a condition clue, not proof.

    Who checks it. Lead inspector or risk assessor

    EPA: Lead-Based Paint Disclosure Rule (Section 1018 of Title X)

  2. 2.Knob-and-tube wiring

    Commonly reported, verify

    Active knob-and-tube in houses built through the 1940s is commonly reported, verify. HUD’s appraisal guide says it can remain if it is in good condition and the service is at least 60 amps. Worth checking for this era.

    How to spot it. Ceramic knobs in an open attic or basement, a fuse panel, or two-prong outlets, with no record of a full rewire.

    Who checks it. Electrician

    HUD: HOC Reference Guide: Electrical and Heating

  3. 3.Asbestos

    Era check

    EPA’s home guide says sprayed or troweled ceilings in homes built or remodeled between 1945 and 1978 may contain asbestos, and that EPA prohibited spray-applied asbestos insulation in 1973. Intact material is not, by itself, a project. Worth checking for this era.

    How to spot it. Popcorn ceilings, older floor tile, and pipe wrap. Do not sand or scrape them to find out.

    Who checks it. Accredited asbestos inspector

    EPA: Asbestos in the Home

  4. 4.Radon

    Regional, depends on location

    EPA says every home should be tested, and that the zone map is not a result for one house. Worth checking for this era.

    How to spot it. A PVC pipe and an exterior fan can mean a system is already installed. Ask for the before-and-after test numbers.

    Who checks it. Radon measurement professional

    EPA: EPA Map of Radon Zones

  5. 5.Hail damage

    Regional, depends on location

    NOAA’s Storm Prediction Center records more large hail on the southern Plains (Texas, Oklahoma, and Kansas) than on the northern Plains (Nebraska, the Dakotas, and northeast Colorado). Worth checking for this era.

    How to spot it. Random soft spots in asphalt shingles, or a listing that mentions a recent roof claim. Ask whether the carrier already paid actual cash value.

    Who checks it. Roof inspector

    NOAA Storm Prediction Center: The NSPP Severe Weather Database

  6. 6.Expansive clay

    Regional, depends on location

    The Colorado Geological Survey calls expansive clay one of the state’s most widespread geologic hazards. Worth checking for this era.
