Cast iron pipes mortgage Florida buyers of pre-1975 homes worry about rarely block the loan directly.
They block insurance, and no insurance means no closing. A sewer scope during inspection answers the question early. Our renovation loan page covers financing the fix.
Why cast iron is a Florida issue
Homes built before the mid-1970s used cast iron drain lines under the slab.
Florida's soil and water corrode them from the inside.
Fifty years on, many are failing.
Miami-Dade, Broward and Palm Beach have large stocks of these homes.
The EPA describes aging sewer infrastructure at the municipal scale; the same chemistry happens under homes.
How lenders see it
Conventional and FHA appraisals do not test plumbing.
An appraiser notes visible problems: backups, staining, odours.
See our guide to low appraisals in Florida.
Hidden pipe condition does not affect the loan approval.
The insurer is where it surfaces.
How insurers see it

See our guide to four-point inspections in Florida.
Cast iron drain lines are a common decline reason.
Some carriers exclude water damage; others refuse the risk.
