Located on the Dorset-Hampshire border, the first-floor offices are part of The Crown House, 2 Southampton Road, Ringwood, and are currently let at £38,527.92 per year.
They are being offered with a guide price of £290,000 to £310,000.
Michael Marchant, senior auction appraiser at Clive Emson Auctioneers, said: “The first floor of this town centre building is held under 125-year lease from September 2004 and is currently arranged as offices, with eight of the ten units let and producing a healthy income.
“The current lease arrangements allow for a service charge to be collected on top of the existing rents, with the parking on site also let separately.
“Based on the current rental income and upper guide price, the gross rental yield is nearly 12.5%, a healthy return.”
The property is one of 228 lots featured in Clive Emson Auctioneers’ latest online auction across southern England.
Another Dorset property in the auction is 5 North Street in Wareham, a commercial investment listed with a guide price of £250,000-plus.
The three-storey building is let to Age UK at £19,000 per year and is held on a 999-year lease dating back to October 1761.
Mr Marchant said: “The property benefits from rear access from Mill Lane, which will be particularly useful when considering options to develop the upper parts or perhaps the land to the rear of the property.”
Bidding for the Crown House offices and other lots opens on September 22, with the auction concluding 48 hours later.
