If you want to avoid overreacting to a fast market, I would start with the pace, the offer gap, and the range of current asking prices.
If you are trying to decide how aggressive to be before touring homes, start with pace instead of emotion. My rule right now is to move quickly on the right property, but keep your numbers grounded because recent accepted offers averaged below asking in Plymouth Meeting, PA.
The recent pace was quick. A typical sale in Plymouth Meeting, PA took 15 days last month, and accepted offers came in at about 97.9% of asking. With supply at 0.83 months, I read that as a market where good homes can move fast, but not every listing has unlimited pricing power.
For a buyer, that changes how I would prepare before the first showing. New listings had a typical asking price of $570,000 recently, active homes sat at a typical asking price of $562,500, and homes that went pending carried a typical asking price of $962,500. That spread tells me Plymouth Meeting, PA is not one uniform price band, so I would define your ceiling and target range before you walk into a home you like.
Get your price range set before the weekend, not after. Shortlist homes by value range and days on market so you know which ones deserve a fast decision. When a property fits, move decisively, but keep your offer anchored to the recent 97.9% average rather than assuming every home requires a stretch play.
