My previous one hasn’t raised rent for five years, and even then he asked if it would be okay with us. Which it was, for even the raised rent was significantly below the market rate and he always responded quickly to any issues we have raised. He was a blue-collar worker who inherited a flat he didn’t want to sell, so rented it out to those who couldn’t afford to buy a property on their own.

Perhaps, if you could explain what “ethical” means in this context.
