I wouldn't say she's trying to push you into a less-than-optimal house so that more savvy, experienced home buyers can buy them, but there may be other reasons than that. Maybe those home buyers are willing to pay more, or she gets a bonus for selling this house versus that house, or maybe those other buyers have "easier" credit and it's a sure sale for her. There could be lots of reasons.
Bottom line, it's YOUR money and it's YOUR house, even if you don't own it yet. If you don't like her, if you're uncomfortable with her, kick her to the curb and get someone else. A mortgage is nothing to play around with, and buying a home you *kinda* like, or that someone is *willing* to sell to you, like they're doing you a favor, you don't need that.
Kick your agent to the curb and get someone else.
