Four houses were bought in the borough for more than £1m each in the last year, figures have found.
In total, the four properties, all in Saddleworth, sold for a combined £7.77m between September 2021 and September this year.
The data also gave two addresses in Rochdale which were bought for more than £1m due to them having OL postcodes.
Including the two properties from Rochdale, the combined total was just short of £10m.
This showed a major increase from over the same period the previous year, when the total was £2.48m.
The research was carried out by Property Solvers, a home buying company and Greater Manchester auctioneer, which used HM Land Registry sold house price statistics.
Three of the houses bought in excess of £1m were based in Grasscroft, while the other home was in Diggle.
The most expensive house to be sold in the last year in the borough was Parklands House, sitting at the end of Parklands Road in Grasscroft.
The house, according to Onthemarket.com, has seven bedrooms and bathrooms and includes a small football pitch and home cinema.
The property sold for £3.15m.
The second-most expensive property was situated on Huddersfield Road in Diggle, selling for £1.8m.
The other two properties, based on Oldham Road and Oaklands Road, sold for £1.6m and £1.22m respectively.
According to the data, Oldham placed 99th across England, Wales and Scotland in terms of the areas to sell the most £1m properties.
Co-founder of Property Solvers, Ruban Selvanayagam, said: “Although there remains a fairly healthy volume of sales in this price bracket across Greater Manchester and the North West, evidence from around the country would suggest that buyer appetite for these types of homes has started to drop in recent months.
“£1m-plus properties – even for the wealthy – are major commitment and indeed affected by the wider economy.
“With continued inflationary pressures and rising interest rates as a result, it would not be too much of a surprise to see a continued cooling off across the high-end property market in the coming year at least.”
