The cottages were built around a slate mine where quarrying dates back to the 16th century.
There has been strong interest in buying up an entire historic slate community in rural Gwynedd after it went up for sale in June.
Homes and cottages at Aberllefenni, near Machynlleth, were on the market with Dafydd Hardy estate agents for £1.5m, less than the price of some London flats.
They had been built around a working slate mine of the same name, where quarrying dates back to the 16th century.
It closed as a working mine in December 2003 but the finishing, crushing and dressing of slate is still undertaken on site.
The slate quarry worker properties had been owned by the family of John Lloyd, of Inigo Jones Slate Works, which bought the Aberllefenni quarry back in the 1960s along with the homes.
They sold the quarry in April and then put the homes up for sale at the start of the summer.
Dafydd Hardy said there had been several enquiries into buying up the village.
They added that firm talks were now taking place with two interested parties.
The estate agency said the 16 tenanted houses and agricultural land would be an excellent investment.
They added: “This is priced realistically for a quick sale, offering an excellent investment opportunity providing income as well as the possibility of increased property value growth.
“The portfolio is mainly located in the historic location of Aberllefenni, set high above the Dyfi Valley in this rural area of Mid Wales. The village of Aberllefenni is surrounded by beautiful countryside amidst the wooded slopes of the Dyfi Forest.”
Aberllefenni Slate Quarry – made up of three smaller quarries, Foel Grochan, Ceunant Ddu and Hen Gloddfa – is one of the oldest running quarries in Wales, dating from the early 16th century.
