Hang on, lodger or self-contained flat? 'Not a share' tells us the latter, doesn't it?
As a former landlord of 14ish years experience letting one shared house, one self-contained, I can only report that, on average, tenants conform quite adepressingly to stereotype.
That is, women looked after the place better, were more responsible and more communicative - if something needed fixing they noticed and told me. Men were concerned only with their own wants. If something didn't affect them immediately they didn't communicate it, there was no sense of 'looking after the place' and working with me to ensure this happened.
Also, younger tenants were self-absorbed and lacked basic practical skills. Older ones, in a house-share, were usually problematic personalities. Thus, ideal tenants for a house share were women aged 24-39, for a self-contained place, women 24+
I know, I know... I'm not suggesting how things should be, I'm reporting how, on average - there were exceptions - they were.
