Manager Janine Lovett said she's had a "large amount of enquiries'' this week.
"It's a good solid home. Somebody will get a bargain,'' she said.
"We've got some people interested who are now liaising with removal teams.
"It all comes down to whether their land is suitable for the house, which is quite big.''
After going weeks with no offers it now appears someone has taken the plunge, with an unknown man putting in an offer, according to 3 News.
The offer would not go unconditional until early December, the station said, as the prospective buyer had not yet organised moving options.
This evening the house was still listed on auction website TradeMe as being for sale.
Relocatable houses are especially popular in post-earthquake Canterbury, where housing resources are stretched and rent and property prices are soaring.
Richard Hutchinson of the Relocatable House Co said last week that the property could easily be shifted around the South Island.
There would be some challenges given it was built from brick with a stucco exterior and tile roof. However an expert team could move it to a new base within 100km in a few days for $40,000-$50,000, Mr Hutchinson estimated.
Once on its new site, it would have to be re-insulated and given a new cladding.
"It looks like a nice, solid big house. Moving it wouldn't be a problem,'' he said.
It would be a bargain for someone, said local real estate agent Daryl Spence.
"For $1, someone will want it.
"A dairy farmer or someone could want it on their farm to put their workers in.''
The house, on its site, would go for around $130,000 in its current state of disrepair, Mr Spence reckoned.
It had a government valuation (GV) of $144,000.
Ms Lovett said once the house was gone, they could tidy up the site, and think about using it for future development.
