The answer should come from pace, pricing, and how well the home fits your plan.
If you are debating whether to wait on a listing or move now, I would not answer that with a blanket yes or no. In Walnut, CA, the better question is whether the home is priced in line with recent market behavior and whether you are ready to act if it is.
Over the previous 30 days, Walnut, CA had 3.63 months of supply, recent offers landed at 100.7% of asking, and a typical sale took 31 days. Over the last 3 months, pending homes showed a typical asking price of $1,100,000. I see that as a market where waiting can work on the wrong house, but it can hurt on the right one.
For a buyer, the implication is to be selective without becoming passive. In Walnut, CA, I would compare the home's asking price, condition, and fit against recent pending and closed activity first. If the home clears that test and matches your plan, waiting usually adds more risk than value.
Decide your walk-away line before you revisit the listing tomorrow. Review the home's price against recent pending and closed ranges before you assume there is room to negotiate later. If the fit is strong and the price is supported, move on it with a clean, well-prepared offer.
