Most families arrive at this after enough hours chartered to feel they are paying rent. That instinct is sound and the arithmetic is often not. An aircraft costs money on every day you do not fly it, and the annual figure surprises almost everyone the first time they see it properly set out.
Our first job is usually to talk you out of it, or rather to put the real number in front of you and let you decide. Below a certain number of hours a year, chartering wins comfortably. Above it, ownership starts to make sense, and fractional sits between the two for people who want the certainty without the whole burden.
Where the answer is to buy, the work is unglamorous: a pre-purchase inspection that finds what the seller did not mention, an import and registration path settled before an offer is made, and a management arrangement that does not quietly consume the saving you bought the aircraft for.
