The important thing is to look at this long range and be able to nip this emotional attachment in the bud. You could easily be co-owner of this property with your sibling's children some day soon. You need to see the inevitable situations now and not 10-20 years down the road. Are you in a position to buy out the other siblings (and their children)? If so, do it and keep the house in the family. The other siblings will not be wanting to be co-owners just so you can live in the house.
