any advice appreciated.

I'm looking to buy a particular house which has been empty and run down for a while. old property with stone walls in the country.

Mostly the walls are painted inside and out without render or plaster. very bad mold smell throughout the house.

A flat roof single storey extension has been built, and what used to be the outside wall is now an internal wall on the ground floor.

No render or plaster has been applied to this wall on the ground floor, only paint on both sides of the stonework.

There are salt growths coming through the paint even at ceiling height on what used to be the external side.

On the internal side is a fireplace which is very wet to the touch and again this has been painted without plaster.

I suspect the source of the damp is the chimney and a non-breathable paint has been used trapping the damp inside the wall.

I would like to know whether this is something that could be easily repaired and what would be involved. Would stripping the paint off and replacing with a breathable paint solve the problem? What is involved in getting the paint off the stone, and how difficult is it? Is there a way to fix this and keep the stone look of the walls, or will it have to be rendered (I know any render should be lime not gypsum).
is this repairable or not?

I'm looking to do as much of the work as i myself, but i have no experience with damp and salt in stone.

You really need to look @ a heritage house type site ;) I recon the paint could be sandblasted off - Maybe there are guys here with more experience of stone houses - I`ve done old , but no stone ones in Sussex
