What may an inspector flag on a 1970s house?

John Long, REALTOR® · 1 Percent Lists Indiana Real Estate · Updated November 9, 2026

Short answerOn a 1960s or 1970s house, expect the usual age items plus a few era specific ones: aluminum branch wiring in some homes built 1965 to 1973, Federal Pacific or Zinsco panels, lead paint questions, possible asbestos in flooring or siding, galvanized supply pipe, cast iron drains, and block foundation water history. Most are fixable or negotiable.

How were houses built in this era?

Ranches and split levels on block basements, crawlspaces, or slabs. Original electrical service was often 60 to 100 amps with two prong outlets in older rooms. Supply plumbing was galvanized or early copper, drains cast iron. Single pane windows, thin attic insulation, and paneling were common. Many have had updates since, so the inspector will find a mix of eras.

What does a buyer's inspector usually flag?

  • Aluminum branch wiring in some homes built or added onto from 1965 to 1973.
  • Federal Pacific or Zinsco panels, undersized service, ungrounded outlets.
  • Lead paint questions on any house built before 1978.
  • Possible asbestos in floor tile, sheet flooring backing, siding, or pipe wrap.
  • Galvanized supply pipe with low pressure, cast iron drains, older sewer lines.
  • Water stains and cracking on block basement walls.
  • Furnaces, water heaters, and roofs at or past typical life if not replaced.

What will a government loan appraiser flag?

Peeling paint is the big one on pre 1978 houses. Also handrails, roof life, electrical hazards, and utilities being on. What FHA, VA, and USDA appraisers flag.

Fix, credit, price in, or disclose?

What John sees in the field

On 1970s houses the panel and the paint come up more than anything else. Both are easy to see from the listing photos, and both are cheaper to handle before a buyer's lender sees them.

Frequently asked questions

Do I have to replace aluminum wiring before selling?

No law requires it. Expect buyers and insurers to ask about it. A documented connector repair often settles it.

Will an FHA buyer be able to buy my 1970s house?

Yes, if the house meets FHA's property requirements, which usually means fixing peeling paint and basic safety items.

Should I test for asbestos before selling?

Testing is optional. Do not disturb suspect material. Disclose what you know.
