“I was shocked,” said Prophete, who refinanced her two-family home in 2006, six years after arriving from Haiti. “I don’t even know these people because they never contacted me. They never called me.”

Prophete is part of a wave of homeowners who say they were blindsided by the start of foreclosure actions on their homes over second loans that were taken out more than a decade ago. The trusts and mortgage loan servicers behind the actions say the loans were defaulted on years ago.

Some of these homeowners say they weren’t even aware they had a second mortgage because of confusing loan structures. Others believed their second loans were rolled in with their first mortgage payments or forgiven. Typically, they say they had not received statements on their second loans for years as they paid down their first mortgages.

Now they’re being told the loans weren’t dead after all. Instead, they’re what critics call “zombie debt” — old loans with new collection actions.

While no federal government agency tracks the number of foreclosure actions on second mortgages, attorneys aiding homeowners say they have surged in recent years. The attorneys say many of the loans are owned by purchasers of troubled mortgages and are being pursued now because home values have increased and there’s more equity in them.

“They’ve been holding them, having no communication with the borrowers,” said Andrea Bopp Stark, an attorney with the Boston-based National Consumer Law Center. “And then all of a sudden they’re coming out of the woodwork and are threatening to foreclose because now there is value in the property. They can foreclose on the property and actually get something after the first mortgages are paid off.”

Attorneys for owners of the loans and the companies that service them argue that they are pursuing legitimately owed debt, no matter what the borrower believed. And they say they are acting legally to claim it.

How did this happen?

Court actions now can be traced to the tail end of the housing boom earlier this century. Some involve home equity lines of credit. Others stem from “80/20” loans, in which homebuyers could take out a first loan covering about 80% of the purchase price, and a second loan covering the remaining 20%.

Splitting loans allowed borrowers to avoid large down payments. But the second loans could carry interest rates of 9% or more and balloon payments. Consumer advocates say the loans — many originating with since-discredited lenders — included predatory terms and were marketed in communities of color and lower-income neighborhoods.

The surge in people falling behind on mortgage payments after the Great Recession began included homeowners with second loans. They were among the people who took advantage of federal loan modification programs, refinanced or declared bankruptcy to help keep their homes.

In some cases, the first loans were modified but the second ones weren’t.

Some second mortgages at that time were “charged off,” meaning the creditor had stopped seeking payment. That doesn’t mean the loan was forgiven. But that was the impression of many homeowners, some of whom apparently misunderstood the 80/20 loan structure.

Other borrowers say they had difficulty getting answers about their second loans.

In the Miami area, Pastor Carlos Mendez and his wife, Lisset Garcia, signed a modification on their first mortgage in 2012, after financial hardships resulted in missed payments and a bankruptcy filing. The couple had bought the home in Hialeah in 2006, two years after arriving from Cuba, and raised their two daughters there.

Mendez said they were unable to get answers about the status of their second mortgage from the bank and were eventually told that the debt was canceled, or would be canceled.

Then in 2020, they received foreclosure paperwork from a different debt owner.

Their attorney, Ricardo M. Corona, said they are being told they owe $70,000 in past due payments plus $47,000 in principal. But he said records show the loan was charged off in 2013 and that the loan holders are not entitled to interest payments stemming from the years when the couple did not receive periodic statements. The case is pending.

“Despite everything, we are fighting and trusting justice, keeping our faith in God, so we can solve this and keep the house,” Mendez said in Spanish.

Second loans were packaged and sold, some multiple times. The parties behind the court actions that have been launched to collect the money now are often investors who buy so-called distressed mortgage loans at deep discounts, advocates say. Many of the debt buyers are limited liability companies that are not regulated in the way that big banks are.

The plaintiff in the action on the Mendez and Garcia home is listed as Wilmington Savings Fund Society, FSB, “not in its individual capacity but solely as a Trustee for BCMB1 Trust.”

A spokeswoman for Wilmington said it acts as a trustee on behalf of many trusts and has “no authority with respect to the management of the real estate in the portfolio.” Efforts to find someone associated with BCMB1 Trust to respond to questions were not successful.

Some people facing foreclosure have filed their own lawsuits citing federal requirements related to periodic statements or other consumer protection laws. In Georgia, a woman facing foreclosure claimed in federal court that she never received periodic notices about her second mortgage or notices when it was transferred to new owners, as required by federal law. The case was settled in June under confidential terms, according to court filings.

In New York, Prophete is one of 13 plaintiffs in a federal lawsuit claiming that mortgage debt is being sought beyond New York’s six-year statute of limitations, resulting in violations of federal and state law.

“I think what makes it so pernicious is these are homeowners who worked very hard to become current on their loans,” said Rachel Geballe, a deputy director at Brooklyn Legal Services, which is litigating the case with The Legal Aid Society. “They thought they were taking care of their debt.”

The defendants in that case are the loan servicer SN Servicing and the law firm Richland and Falkowski, which represented mortgage trusts involved in the court actions, including BCMB1 Trust, according to the complaint. In court filings, the defendants dispute the plaintiff’s interpretation of the statute of limitations, say they acted properly and are seeking to dismiss the lawsuit.

“The allegations in the various mortgage foreclosure actions are truthful and not misleading or deceptive,” Attorney Daniel Richland wrote in a letter to the judge. “Plaintiff’s allegations, by contrast, are implausible and thus warrant dismissal.”
