Allt-Na-Craig House in Ardrishaig, near Oban, was built in 1856 and is said to have retained many of its original features.
The guest house has five en suite letting bedrooms, a dining room and lounge as well as owner’s accommodation.
There’s also a two-storey coach house within the grounds, which is currently used as self-catering accommodation.
The business was acquired by Philip and Caroline Palmer from Wiltshire and, according to selling agent Christie & Co, represents a “completely new venture” for the pair.
“There was strong interest in the Allt-Na-Craig due to its loch-side frontage and strong trading performance,” said Ken Sims of Christie & Co.
“We have, over the past few months, seen an increase in demand for quality guest houses with solid trading figures and I expect the market to continue to pick up throughout 2014.”
Adrian Foster of Christie & Co’s sister company Christie Finance, which secured finance for the Palmers, said: “I was delighted to be able to secure the funding for Philip and Caroline.
“Once again it goes to show that there is funding available to first time buyers and that using a specialist broker gives clients the best chance of securing it.”
Allt-Na-Craig House was sold for an undisclosed sum from an asking price of £495,000.
