Not rtft, but excellent news. Of course, people will still find a way to discriminate anyway, but at least it's a step in the right direction.
I'm a LL, I favour single mothers with one or two dc as tenants. Mainly because I've been one myself, I was fortunate from a financial pov, however I'm aware many aren't, and on the whole they get a shit deal benefits wise compared to couples and/or those with several dc.
The only occasion I had any problems was when an excellent long term tenant lost her job through no fault of her own, and housing benefit completely fucked up her claim repeatedly. She still tried to pay as much as she could from the pittance she received, but I firmly believe if any ll can't manage with a couple of months rent paid late, they shouldn't be a ll. As soon as they paid her the outstanding benefits she paid me.
My nightmare tenants were a couple where only one worked. They didn't look after the property and then seemed surprised that as a single working parent I wouldn't accept the excuse they didn't have time. Then when the dp had to take a lower paying job they started falling behind with rent, and they had the nerve to ask me to drop the rent because he couldn't find anything better and she was a sahm.
