Women also don’t want to date a 30 year old man who still lives with his parents, its a huge turn off to most of them.
Throughout life, men are judged on their living/housing situations whereas women are rarely ever judged on it.
The only time a woman would be judged negatively in the sexual marketplace for her living/housing situations would be if she were homeless/living in a homeless shelter. With homeless/borderline homeless women, their looks rating would likely also suffer as homelessness is not good for looks. Fewer women are also homeless as compared to men. For housed women, there's not much difference between living with parents, living with roommates in an apartment or a detached house, renting and living alone, or being a homeowner and living alone.
About 15 years ago, I knew a woman in her late 20s living alone who was dating a man 6'0"+ and with a solid income. That's the equivalent of a man in his late 20s living at home and having sex with 21-27 year olds who rate 7.5+ in looks. That's unlikely to happen for a man in his late 20s living with parents. There are exceptions to rules though. On this board,
@BPH is a late 20s guy who lives in his parents' house & has had sex with 80+ women, though he is 6'0" and is fit.
For men, this is how women evaluate them for their living/housing situations based on the age of the man.
18-23: There's a lot of variability in this age range. A lot of this depends upon if a man is attending college or not and if he's interacting with women attending college or not. Most women will generally consider it to be ok to be living at home during this time frame though it's not the living situation that 18-23 year old women prefer with men 18-23. Women 18-23 prefer men 18-23 to either be living alone in a one bedroom apartment or have roommates in an apartment or house. Between 18-20, a lot of women and men are in college dorms. College dorms stink. You're typically sharing one small room with another person, which can affect sexual logistics. In a lot of colleges, the typical housing path for students is to only live on campus freshman year or maybe freshman and sophomore years. It depends on the culture of the college.
If you're living at home in this age range, then you'd better have a good reason why you're living at home instead of with roommates. If you have a good reason, there's not much of a penalty for doing it in this age.
24-29: By 24-25, most men who've attended college have completed their bachelor's degree. Men typically finish high school at age 18. If a man goes straight from high school to college and completes it in a standard 4 years, that makes him 22 when he graduates. In evaluating most people's paths, there's usually a 2-3 year buffer zone in the evaluation. That can cover taking 1-3 years off before starting college, taking 5 years to graduate college, going to school part time while working, etc.
I also believe college degrees are overrated and trade school is a better path. The trade school path is a little less conventional, but most who don't go to college and get a trade certification usually get it by 25.
When women consider men 24-29, they expect that they've completed a major part of their education, such as a bachelor's degree or a trade certification. Some men will get advanced level degrees during this time frame.
Most women expect a 24-29 year old man to be living independently in some way. There is a harsh penalty for living with parents by age 24. Most 24-29 year old men will either have an apartment alone or with roommates. Some will be renting houses with roommates. A few men will even buy a detached house or a condo/townhome by this point in their lives, though unmarried/never married men typically don't buy houses until they are 30+.
In more urban areas, there's some debate about whether a nicer apartment with roommates is better than an adequate, somewhat older 1 bedroom apartment alone. I think the 1 bedroom apartment alone is better.
There are some single fathers by 24-29, but this typically happens in less educated groups. Men with bachelor's degrees + are typically childless 24-29 or they've had their first kid with some woman by then and have yet to become separated from her.
30-39: This is the range where roommates become less acceptable. Women typically expect childless men in their 30s to have moved beyond the roommate phase in their lives. The only exceptions are highly expensive cities in the USA and Western Europe. In the USA, these cities are either in the Northeast or on the West Coast.
In bigger cities, when women considered childless men in this range, they start to become more particular about his apartment. An adequate, older one bedroom apartment becomes less likely to impress women. Better than average apartments start to become more essential for the man.
Late 20s/early 30s is when childless women with bachelor's or advanced degrees start to buy their own houses. Some of these women might look down on a guy in an apartment. These are mostly careerist women anyway, so it's not a big loss.
Mid to late 30s is when a lot of people who married between 24-29 get divorced. It's common to see more 35-39 year old single fathers. 35-39 year old childless men are becoming more commonplace now because 35-39 year old men now were 1980s born Millennials.
It's important to note one changeover in one's 30s. When women consider men 35+, possessions and money take on a greater importance and looks take on less of one, though looks still matter in 30s/40s.
Living with parents in 30s and not being independent is still bad.
40+: Things get really random and scattered here. Millennials are starting to turn 40 now and the 40 year old Millennial now looks much different than the 40 year old Boomer in the 1980s/1990s or the 40 year old Gen X'er in the 2000s-2010s. The 40 year old Millennial is more likely to be childless and often never married, though there are some 40 year old childless divorcees.
There are way too many different things that happen in this age that it's not easy to describe.
