The taskforce was appointed by the Social Development Minister Nelson McCausland.
It was asked to examine the impact of negative equity and repossessions.
The taskforce has warned that the number of people falling behind on their mortgage payments could increase as interest rates begin to rise.
The taskforce is now undertaking further work aimed at developing policy recommendations.
Northern Ireland suffered a huge housing bubble followed by a crash that saw prices fall by almost 50%.
As a consequence, rates of negative equity are much worse than elsewhere in the UK and repossessions have also increased.
A major "at risk" group identified by the taskforce are households who undertook "equity release" remortgages at the height of the market.
They are people who increased their mortgages to release cash for other purposes, such as home improvements or to finance buy-to-let properties.
In 2007, 74% of remortgaging in Northern Ireland was for equity release.
The taskforce said this category of "credit hungry" borrower was disproportionately active in Northern Ireland.
Lower income groups who took out "second charge" mortgages with subprime lenders are also at high-risk.
The taskforce said those lenders have shown "a more tenacious approach to arrears management".
However, it said, in general, lenders have shown "forbearance" and if they had not done so rates of repossessions would be higher.
The taskforce warned that, despite a gradual recovery in the Northern Ireland economy and the housing market, major risks remain.
It said that the Northern Ireland economy "remains some distance from reaching escape velocity"' and that borrowers are "poorly equipped to absorb future income shocks".

Buchanan, 25, came through the Quins academy set-up to make his debut against Leicester in 2010, and has since made 116 appearances.
He toured Argentina with England in 2013, but did not play a Test match.
"Rob has made significant strides this season in nailing down the starting hooker position," director of rugby John Kingston said.
"His love of the club is there for all to see and he will play a significant role in the quest for more silverware over the coming years."
The front-rower joins Charlie Mulchrone, Ross Chisholm and Dave Ward in agreeing extended deals with the club.
Quins' academy side has brought through a strong contingent of first-team and international players, with Buchanan, recent England and British & Irish Lions call-up Kyle Sinckler, George Lowe and Joe Marchant all adding depth to the squad.
"I have been with this club since I was 16 and it was an easy decision to extend my time," Buchanan said.
"To be able to work under the guidance of Adam Jones and Graham Rowntree for the coming seasons is incredibly exciting for me, and I am grateful to John Kingston for the opportunity to continue my career here at Harlequins."

The 32-year-old, formerly with Watford and Cardiff, has agreed a deal until May 2018.
Cowie played with Ross County and Inverness Caledonian Thistle and has 10 international caps.
"He'll bring experience to the table, which is invaluable when you're trying to blood younger players into the first team," said Hearts boss Robbie Neilson.
Speaking to the club website, Neilson added: "He's played in the Scottish top flight before so knows our game, and he's played at the highest level down south and won a Championship, so I know he's a winner.
"Having played in England, he'll show the players here the level they'll have to get to if they have aspirations to play there themselves."
Cowie has made more than 450 senior club appearances, scoring 52 times.
The Northern Ireland housing market remains "dysfunctional" and poses a risk to economic recovery, a Stormont-backed taskforce has concluded.
