Ozengell Grange in Ramsgate, which was built circa 1711, is to be offered at auction.
The Haine Road property, which also has a barn thought to date from the 15th century, sits on a plot of 3.5 acres. It includes other outbuildings and stables.
The Grade II property, listed in 1974, has been in the same family for many years and is being offered with a freehold guide price of £600,000-plus.
The two-bedroom property is among 175 lots listed for sale by Clive Emson, the land and property auctioneers, ahead of its next sale, which is its 250th.
Auction appraiser Jon Rimmer said: “This is an extremely rare property to come on the market. It is a large, detached house with an associated barn within 3.5 acres of gardens that are overgrown.
“Full of historic features, this property is likely to whet the appetite of builders who will be able to see huge potential.
“It requires refurbishment and by doing so offers any new owner the chance to create their own interior.”
There are period features throughout, including inglenook fireplaces and exposed beams, with the gardens having several period outbuildings and a walled garden.
The sale with Clive Emson Auctioneers will conclude on Wednesday 12th June.
