Our major concern is not staying in a rental that others use, rather it's traveling by plane and going through the airports.

Listened to this podcast with Hunter Thompson and Reed Goosen on a plane ride recently and it touches a bit on what sort of person you need to become to attract amazing mentors.

I am going to do the conventional loan, but i am planing on living there for a year or two.

You should always have two block planes, one good one for actual carpentry work, usually a Stanley product, and a beater block plane by HD Buck Bros.

if it’s a good bit away from the flood plane you should be all right I actually have a house in there (not in the floodplain)

If you have an obvious duplex on the front, the ADU would not be permitted in any case.  2 units max.The height max on the ADU should be 24', but you do have bulk plane to contend with - and to your point, NO upper story decks are allowed on an ADU anywhere (back yard privacy thing). 

Nobody goes to Costa Rica to hear the noise of planes.5.
