Suburban Rhonda - thanks for explaining. It is awful how many people have no real hope of controlling their housing situations, and once housing goes belly up, so much of the rest of your life can follow.
What I find unfair about home owning, not landlords specifically, is that when I look at people my age and a bit older, some bought just before the huge boom, some didn't quite get there for whatever reason. Now, many who didn't buy have always worked as hard, even earned as much, and are now stuck in a position of having to pay far more in rent for a nasty place than others are paying in mortgage repayments for a nice place. They won't have anything to show for it at the end of all this renting, and literally every week the price of buying rises, while compared to those paying mortgages, the renters are simultaneously paying out more of their income on rent - a double whammy of getting poorer no matter what you do. Many people are able to benefit hugely from the current housing issues as landlords, through no skill or work of their own - if the economy and housing availability were different so that there was a good supply of property and low supply of possible tenants, then they'd benefit less through no fault of their own. I don't blame them as individuals. Unfortunately the government have a vested interest in pandering more to the votes of homeowners, and in inflating away their own debts.
Where I do blame landlords is those who really take advantage in the most mean ways - refusing to maintain properties decently or let them in a basic clean condition, simply because the market means they can, and will still let it. There are those who have no human regard for the welfare of their tenants, and will skimp on even the most basic things, no matter how good a tenant is. I doubt the OP's friend's landlord is like this, as if so she'd probably be partly relieved to leave.
Sorry for long post but btw, I do know plenty of people (I accept probably a minority) who have retired in their 30s to live off rental income, based on a home bought by their parents. For example, a child goes to Uni, parents buy a house there for child to live in and to rent out the other rooms to student friends. By now, mortgage gone and lots of money made, especially if you still rent out some rooms. Not to mention that in all those years, you have saved more of your wages because you were not paying astronomical rent.
