This was all I was really getting at. You don't need to explain yourself to me and I'm not judging you, just bringing up some points you need to consider. It's your parents money and house, so if your dad decides you need to get rid of everything do you have a good plan for that? It's my own preference not to buy from someone under 18 and most of my reasoning would have to do with legality of live guarantees from someone underaged, being able to bring you to court over a dispute and not have it be thrown out, etc. I don't even know if that poses a legal problem, just something I would be weary of personally and would be less inclined to 'deal with.' I am aware there are plenty of kids under 18 that are better to deal with than adults, before someone makes that comment, but that's why I'm pointing out the legal safety web I rely on when doing business with people I don't know.
If you're doing it responsibly then good for youI haven't even considered pairing yet and I know the answers to every one of your questions simply, so I have to assume you haven't done adequate research on the topic yet. One thread asking for answers from a handful of anons doesn't give a full enough picture to be educated on the topic. Perhaps you already know most of the answers from your research and are looking for reassurance. That is unclear to me. Take a deep breath and slow down. Your opening post suggests an urgency that isn't conducive to success.
