On Cape Cod and most of the South Shore, the septic inspection is the thing that kills sales. Here's what a failed Title 5 actually means, what it costs, and what your options are.

Title 5 is the Massachusetts code for septic systems. Any house on septic has to pass a Title 5 inspection within two years before it can be sold (or three years if the system gets pumped every year). The inspector checks the tank, the distribution box, and the leaching field, and writes a pass, conditional pass, or fail.
Most of Cape Cod, Plymouth, Marshfield, Duxbury, Kingston, Pembroke, Carver, Wareham, and the rest of the South Shore outside the sewered downtowns are on septic. So this comes up constantly.
You can't close a normal sale with a failed Title 5. The buyer's lender won't fund it. So either you fix the system before closing, or you escrow enough money at closing for the buyer to fix it (usually 1.5 times the estimate), or the buyer takes it as-is and handles it themselves.
The town health department also gets a copy of the failed report, and you're generally required to fix it within two years whether you sell or not.
This is the part that surprises people. A straightforward replacement on the South Shore runs $25,000 to $40,000. On the Cape, where lots are small, groundwater is high, and a lot of towns now require nitrogen-reducing systems, $40,000 to $70,000 is common, and we've seen bills over $90,000 near the water.
Then add the engineering, the town permits, and the months it takes to get on a contractor's schedule. It's not a quick fix.
Fix it and list. Makes sense if the house is otherwise in good shape and you can float the repair cost and the time. You'll get full market value.
Escrow and list. You find a buyer willing to close with a repair escrow. Fewer buyers will bite, and you still pay for the system, just after closing instead of before.
Sell as-is to a cash buyer. You skip the repair, the engineering, and the waiting. The offer accounts for the septic cost, but you're done in a couple of weeks instead of six months. This is a big part of what we do. We buy houses with failed or uninspected systems all over the Cape and South Shore, and we deal with the town and the contractor after closing.
If you're thinking about selling and the house has an old system, or you don't know when it was last inspected, you don't have to get the inspection before you call us. We'll look at the property, and if the system is a question mark, we'll price it that way and handle the inspection ourselves after closing. That saves you the $400 to $600 inspection fee and the two-year clock that starts when it fails.
A failed Title 5 doesn't mean you can't sell. It means you have to decide whether you want to spend the money and the months to fix it, or sell it to someone who will. Call or text 508-789-2497 and we'll give you a number on the house as it sits.
Two years, or three years if the system has been pumped annually with records to prove it.
Yes, but not through a normal financed sale without a fix or an escrow. A cash buyer can take it as-is.
Yes. The inspector sends the report to the local board of health. You're generally required to repair within two years.
