If the cost of living rises significantly which being outside the customs union entails, those wage rises and house price drops mean nothing.
Not only that but investment in businesses has dropped off considerably and the number of jobs available may well decline particularly in areas which are highly dependent on single industries like car manufacturing. This in theory will force a lot of wages down.
If there are more people out of work claiming benefits then there is less in the treasury. Combine with businesses moving offshore for EU reasons which has the side effect of them all paying less to the treasury. This means that services are squeezed further - and frankly there is nothing left to squeeze so they collaspe completely meaning many more affluent types go private for things like healthcare - or taxes on those in employment rise, which affects how much they have to spend and again raises the cost of living for the employed.
A tank in the economy which includes a house price drop isn't good news for everyone. It could involve interest rate rises (which mean a cheaper house isn't any more affordable anyway) and leave some with negative equity or otherwise unable to sell due to greater unemployment in their area, thus meaning that they are trapped, more likely to default on their mortgage and lose their house completely or lack mobility to start a new job in a different area.
The question really is if wages are going up to compensate for this cost of living, or changes to the economy are people really actually better off or not? Its about relativity of cost to the person on the street not raw ticket price cost that really matters.
I'm also not convinced that wages are rising for everyone; wages increases have been fuelled by skill shortages in certain professions where skilled workers have left the UK but those who are unskilled haven't necessarily benefitted. Its more that there has been even more of a widening of rich and poor.
I'm sorry but 'but wages are going up, and house prices are going down and this is good, what's not to like?' is a lazy, simplistic and rather shallow take.
The national economics is a bit more complicated than wages and house prices.
