There are an awful lot of posters here who clearly know nothing about the housing market but like to think they do. They are also very quick to mention my tone but seem oblivious to their own 
I have been looking at 2nd homes ( note- homes not a holiday cottage to use 6 times a year and / or rent out as a business) for years.
I suppose you also despise people who buy a house and rent it out, depriving locals of houses? Oddly, I've never seen any outrage here when they ask for advice !
Many of those I've had my eye on have not sold in a year or more. The prices are dropping and the actual percentage increase in homes in the north is very low and sales are slow. They are also well within the price range of many locals. One reason for the price hike around York is that people now commute to London daily, and also they have moved out of London so they have money to buy larger properties.
I had barely got the phrase '2nd home' on the page when a few posters waded in with their view on how I ought to live my life or spend my money, without knowing a single thing about the circumstances. It smacks of envy rather than genuine concern.
Any vendor selling a house has the choice of who to sell it to. If it's on their conscience that they only want it to be sold to locals, they can decide to do that.
People were incredibly rude here when they knew nothing about my circumstances. If you don't agree with people having 2 homes, fine, but this is not the place to come along and berate people who ask for advice on locations. Do you really think it's going to make any difference?
Thanks again to the posters who offered advice.
