Compression tests are a poor indicator of engine health. In fact, Continental has stated that compression testing is only useful as a “leak test.” You can have marginal compressions and a good engine or vice versa.
Sounds like you are new at this. I strongly recommend that you retain Savvy to help you manage your pre-buy. It is extremely cheap insurance to have an expert in your corner.
By the way, “low time” is not always a good thing. If are looking at an airplane that has only been flown infrequently, you are often looking at trouble. The very worst thing for an engine is inactivity. If it sat idle for long periods of time, I would be extremely wary.
