Today, four proud homeowners are through to this week's big final.They will hand over their keys for a second time to five nosy neighbours, who will get one last look around the homes to help them decide who has the winning home.They'll judge the perspective champions on three key criteria; the functionality of the home, the ambition of its interior design and finally, the ‘X factor'.Battling it out today will be a flat, a semi detached property, a detached house and a wildcard.Which of these superb homes will be the Best House in York? It's down to our amateur property aficionados to decide.
