Actually, I think that #5 is the most important. After all, you’re not marrying the girl’s father or her Yichus… you’re marrying her. You have to make sure that *she* is someone whom you can live with. You have to make sure that *she* has the middos that you want in a future spouse, that *she* shares the same hashkafah as you, that *she* is someone whom you can get along with and that *she* is someone with whom you want to spend every day of the rest of your life.
Having a father-in-law who is talmud chochom or a ba’al tzedaka, or a prominent askan, or her having an important yichus may all be a nice bonus, but the bottom line is that you have to look at the girl first. Everything else is just gravy.
