Would it be possible of him to sell it to you when he wants to sell? At least in some countries, parents are allowed to sell a house to their children way below market price without any problems with taxes or anything.
No need to sell it really. Just a change over of the title deeds might do the trick. Something very similar happened to me a few months back. I "bought" a house to let when I was 20 in 2011 and my parents "bought" it for me. Basically I gave them my savings for the deposit and they had the mortgage in their name because I was too young for a mortgage in my name. I paid the mortgage off myself a few years later.
In March this year the deeds where put in my name. It cost about 350 quid and that was it. My parents avoided capital gains for the "disposal" of the house as the gain was below the threshold and I avoided stamp duty as no money changed hands. Even with a second house and the much less generous tax exemptions we still paid nothing to completely transfer a house from one person to another.
The OP should speak to a solicitor. The second I spotted his post "solicitor" was the first thought in my head. Changing the deeds over seems far simpler and much less expensive than selling a house and ensures a stake in it. The devil is in the detail with things like this. From past experience I've learned that parents rarely know best.
Perhaps it might be worth he OP saving up ready for paying off his siblings share of the house or perhaps they can all make use of the house themselves? Many options might open up if he's told what his possibilities are.
