If you can afford to take the plunge, a lot of used light twins are available in various states of condition. If you have a big job to do, one requiring extra cabin space and performance, a light twin may still be the answer. And if you want the ultimate in redundancy, a second engine still makes sense, so long as you are willing to invest in training and understand how to use it.
However, an old twin can be a money pit. I’d advise having a most-thorough pre-purchase inspection done, under the supervision of your own broker, before making a final commitment. Have uncommitted excess funds, possibly matching the amount of the purchase price, to cover the inevitable surprises that may show up in the first year of twin-engine ownership. If you get lucky, you can always use some of your sinking fund to redo the avionics or cosmetics.
You’ll need a maintenance shop that is familiar with your choice of a twin. Given the age of most twins on the market, corrosion is almost a given, so it needs to be managed from the get-go. It helps to have a mechanic who knows where to look for potential trouble.
