She said just one person had made an enquiry to date, "but a lot of people are really hesitant because of the stigma attached to homelessness".
"I describe these people as 'displaced families' and it's due to the rental market being so hard to find anywhere to live.
"These families are in totally different circumstances than the rough sleeper-type or homeless person.
"Three years ago, when we first started, we used to deal with older single males between ages between 45 and 70.
"The whole thing has changed and now it's predominantly families, and they can be large families."
She said those displaced families were slow to come forward, "they can be embarrassed to come forward or don't know there is a service to look after them".
Mrs Peiffer said she wanted to reassure those thinking about helping them out that all families were thoroughly vetted before moving in.
"We go through a process where we will interview a family and match them with people.
"We keep a close eye on our families and work closely with our host families and visit every second day, or once a week.
"We know who the rat bags are, so we make sure both families are safe," she said.
