Interior & Health/Safety

Some hazards aren't a problem until you renovate. Knowing where they hide lets you plan, and budget, instead of being surprised mid-reno.

The ten second check

What else is typical in a house this age?

Type the year the house was built and I will tell you what else tends to be true at that age, what it costs, and what to ask. One number, ten seconds.

A guess is fine. 1965, or just the 60s.

Anything worrying you? Tap any that apply, or skip it.

Free. No account. Educational and impartial, not a home inspection.
