Kate Forbes MSP will raise the shortage of affordable Highland homes in the Scottish Parliament chamber during this week's General Questions.
The MSP for Skye, Lochaber and Badenoch has scores of housing cases across her vast constituency, and anticipates more Scottish Government-funded homes becoming available by 2021 based on the 50,000 target.
Last week a Highland Council report highlighted the general "upward" trend of homelessness on the Isle of Skye which was creating "considerable difficulties for the housing team", whilst over in Badenoch people can struggle to get on the housing ladder because house prices dwarf the median local wage.
Kate Forbes MSP said: "Housing is foundational to everything else – jobs, education and healthcare depends on people finding affordable housing.
"In the Highlands and Islands, we've had a long history of second homes, low building rates and higher costs driving up house prices so that housing is almost outwith the reach of most people.
"Whilst tourism is a good news story it has put even more pressure on housing, particularly the rented sector where more money can be made. In light of that, it is critical that more housing is built in the right places.
"The Scottish Government has a target of 50,000 affordable homes, backed by £3 billion. I'm keen that as many of those homes are built in the Highlands as possible.
"Last month's announcement of 200 new affordable homes in Skye and Lochalsh was an absolutely brilliant start, but there's more to do."
