My opinion (and its just my opinion) is that unless you have a good sense of the valuation you want and the justification behind it (comparable, multiple of some metric you think is defensible), you are better off agreeing to talk and not filling in any numbers beforehand.u00a0u00a0u00a0 By filling in numbers you risk either selling yourself short or appearing inexperienced by asking for a too high valuation.u00a0 By listening first and seeing if they have an offer or proposed valuation, then you can push at their rationale and then see how you can counter with a rationale of your own to get the valuation higher (unless the valuation is high enough that you just want to proceed).
