So the wife, bless her heart, has been pushing me to go finish my multi commercial and MEI so we can buy a twin instead of never finding anything we like in the single market. I have been trying to tell her I don't think we can afford a twin. However, she rightly pointed out that I do not have any hard numbers to back this up. I have a decade a numbers on operating 172s, T41s, Arrows, and a Dakota but nothing on a twin.

So please help me convince her its a bad idea, or convince me its a good idea lol. We would consider a Seneca II/III - prob in the 200k range. Here are my "guestimates" on what it would cost to own/operate.

TLDR; I believe it will cost about $240/hr to operate, and $12k/yr to own. Affordable...but I worry about ~90k in engines coming due. Hourly cost is one thing when you can put away money to pay for that engine...tough to do with a midtime engine that likely wont make TBO and lets face it havingly mostly flown NA planes th odds of a costly mistake are high. That is the sum of my argument - while we can afford the upfront cost and operating costs over timee we cannot afford the TWO big engines and the insurance I feel is likely to be above 4k for me. I only have 400 hours of retract time and no Seneca time (my multi time is less than 10 hours right now). Though if we do go this route I would finish my MEI with prob 30 hours in a Seneca I.
