Look at spending priorities
If you go to your date's place for dinner, pay attention to the surroundings. Thakor, the author and CFA, says you should be on the lookout for telltale signs of a spendthrift.
"In Texas they call it big hat, no cattle," Thakor says. "When the person lives in an extravagant apartment in an expensive neighborhood, but it's very sparsely furnished, you have to wonder what's going on there. If they can't afford to furnish the place where they live, you might wonder about how they prioritize their money."
