The best question you can ask is...why.
In no particular order...
Why's the share for sale?
Why's the bank got so much money in it? Reluctance to spend it?
Why is there a pilot hours limit?
Why does it do so many hours / never fly?
Why are the monthlies so high/low?
Why are there 4 people in the syndicate but only two names appearing in the tech log?
I'm in a 12 person syndicate. 4 of us fly regularly, 4 occasionally and 4 seldom. I knew the aircraft before I bought my share, and watched what a couple of shares sold for before I bought one. I knew it had a new engine and had been reasonably well looked after but would likely need a cash call. On average, one share per year comes on the market in it, and it sits on the market for about 3-4 months. I was sceptic at first having been in a 4 person syndicate previously but have been very happy with 12 - it just depends on the group. It's rare I can't find someone to come with me and cost share.
