There is no question that guys that have their own place, get laid more than guys that still live with their parents. Guys that live alone or with a buddy, can always bring home a girl he just picked up. On the other hand, if you live with your family, it is weird at best to bring a girl to your room; knowing that your family members could hear her moans in the middle of the night. In contrast, a guy that lives a lone or with a room mate (wigman) can always organize a party as an excuse to get a girl to his place. Or simply invite her over, since you will be cooking something, which will lead to more fun activities later on.
However, if you don't have your own place the, you need to pay for a motel and some girls will not want to go to a motel (hotel), thus the reason PUAs find wigmen to share a place with, instead of living at home!
