I mean, if the whole idea is to get a woman pregnant just to have a kid, then I figure adopting and raising the child on your own is a viable option. You don't have to worry about the mom keeping the child at the last minute, making some kind of financial arrangement since I doubt a woman will carry a kid for 9 months for a guy she barely knows without some type of incentive, or can she take you to court for child support. You apply, go through the process, and have a child you can raise for yourself. As far as what I would look for in a kid I'm adopting, I would look at their temperament as well as the absence of any major emotional problems. I don't need a budding psychopath with a temper in the same house with me. Yeah, I can discipline them, but I also have to sleep at some time and don't want to be set on fire while lying in bed.
Now as far as getting a surrogate, I'm assuming you mean she just bears your child and leaves. So you want to find all these characteristics that you like in a woman, get her pregnant, and then tell her to leave? Why? If you found someone you like, why not just date her, marry her if you believe in that, and you two raise the child you want together? Truthfully, I wouldn't go through all the searching for a woman just for a kid that doesn't exist yet. If I find a person I like, I'm staying with them and the kid would be a product of that union instead of the union just being about producing a child.
