What counts as "guidance" anyway? A realtor can't be relied upon for structural issues, you'll need an inspection. They can't tell you anything about the market that you couldn't dig up yourself in 5 minutes searching Redfin. HOAs, contract language, and other legal matters will need a lawyer. You're basically gonna have to find a dedicated professional for anything that matters.
The limited benefits I can think of are:
- you're buying in a tight market, and they can find some off-market listings through their network
- a reputable buyer's agent might make your offer seem more legit
