Declined the owner's policy to save $410. Cost me $3,100 three months later.
First rental, a $168k three bedroom in a modest inner-ring suburb. At the closing table the settlement statement had the lender's policy on it, which the bank required, and then a line for a simultaneous issue owner's policy at $410. The closer asked if I wanted it. I asked what it did. She said it protects your ownership if there's a problem with the title. I'd already read the commitment, the search was clean, and I was tired and over budget on inspection stuff, so I declined it and initialed the waiver.
Three months later I went to the bank about a small line of credit against the house. Their title search turned up an unreleased second mortgage from an owner two sales back, from 2004, balance $19,500. Paid off in reality, apparently, but never released of record.
I had no owner's policy. The lender's policy covered the bank's lien, and the bank's title company had insured over it for them, which did nothing for me. So clearing it was mine. Attorney to chase the successor servicer for a release, plus an eventual affidavit and recording, $2,740 in fees, $360 in recording and misc. Four and a half months. The credit line went on hold the whole time and I lost the rate I'd been quoted.
If I'd bought the $410 policy the underwriter would have handled the clearing and the cost, since a defect of record existing at the time of my purchase is the kind of thing an owner's policy is meant to cover, subject to the exceptions on Schedule B.
What I'd do differently: buy the simultaneous issue owner's policy every single time. And read the closing package a week early, not at the table when I'm tired.
