New pilot, first post. Trying to decide between just renting for a bit, or biting off a purchase. My goal is to build time and get my instrument rating. I want to fly it for 2 years (150-200 hours) to see if I want something bigger (or sell because of limited use or unexpected costs). Would like to get a SR20 or most likely a C182 to learn on, something with good avionics and less than 500 hours on engine. Budget is $135k. I am 40 years old, with a wife and 2 kids under 6. Initially it will be me and my 90lb German Shepherd in the plane. I am talking myself into this, but maybe that is ok. I also may be better off renting for a bit to see how much I fly and what type of aircraft fits my mission. I am scared of large unexpected costs (over $5k). Any advice from anybody that has been down this path with a good or bad experience? Bonus question- would a 90lb dog fit into the baggage door? I am worried about getting him in and out without injury or damage to plane. The dog is a big factor, as he goes everywhere with me. Another reason I am considering ownership over rental. Any advice is greatly appreciated!
