The home was foreclosed on in 2007 after the mortgage wasn't paid.
Jeffrey Navin appealed the decision twice but lost, and just weeks ago a judge denied an attempt to reopen the case.
"The longer this goes on, obviously, in our world, we're going to look at everything, turn over every stone," said Easton Police Chief Tim Shaw.
The Navins also owned Eversource more than $100,000 in unpaid electric bills.
The Navin family said the financial situation has nothing to do with the couples disappearance and said in a statement:
"We are shocked and saddened at the unexpected disappearance of Jeff and Jeanette Navin. There are no words to describe the impact this has had on their parents, siblings, and children. We wish only for their safe return and we ask for anyone who has seen either of them since Tuesday, August 4th, to contact the Easton police. Financial issues recently reported by the media have not been proven to be a factor for our family members’ disappearance. Information from the authorities indicates that there are available funds still in their bank accounts that are untouched. We, the entire Navin family, ask for privacy and respect during this overwhelming and troubling time."
The couple's vehicle was discovered in Westport on Aug. 9. It was just off exit 42 of the Merritt Parkway with a window smashed.
According to police, Jeannette Navin is a school library aide in Weston. Jeffrey Navin owns J&J Refuse.
Both had only recently moved to Staples Road in Easton.
There is someone living at the home in Guilford however they had no comment on this case. The home wasn't the only one the Navins owned. Several others were tied to Navin's garbage company.
According to state records, he listed a Weston property and a Westport mansion as his home address.
