Should I Buy a House at 23? Hi, I currently earn £20k per year and am lucky enough to have £30k in my bank account which I have saved up/been gifted. 

&amp;#x200B;

I live at home and would like to move out soon. I have been looking at purchasing a house worth approx £100k, taking out a £70k mortgage. When I add up the monthly expenditure on mortgage, heating, electricity, water, internet etc I am left with approximately £700pcm for food, entertainment etc. 

&amp;#x200B;

Is this a no brainer and I can definitely afford to do this or are there other things to think about?

&amp;#x200B;

Many thanks for any help.
