the way i see it: the rich are getting richer and if you have to lend money to do this then its a deffo nono. only people who have loads of money and been in the game a long time are benefitting from the situation.
in my area: 100k property £600 a month mortgage, and the rents around here would be about £500 on a 100k property. you work it out its not rocket science is it.
