Low Time and Insurance - Cessna P206

I am a student pilot getting ready to solo next week (26 hours now). I
am interested in a 1/3rd share of a '65 P206 due to my large family.
Apparently annual insurance is currently $1950. The seller has
contacted the partnership's insurance broker who has checked with
their current insurer who states they will not insure me when I get my
private. The selling partner has expressed concern about wasting the
broker's time.

I obviously am not interested in buying into a plane I won't be able
to fly. Does anyone have any thoughts or experience on this?

Thanks much.
