If subordinate liens cannot be foreclosed upon in California, lenders will stop making junior liens and extending second-position lines of credit.

Because once the HOA tries to claim from the surplus, they’re essentially saying: “We’re a junior lienholder and subordinate to the mortgage.”That’s risky for them, they could be behind others in the queue and get nothing.Instead, HOAs usually prefer to go after you, the new owner, because the lien survives the foreclosure and attaches to the property.
