Is fee simple vs lease hold profitable?

[Danielle Dorien]

Needing some guidance as I am a first time home buyer, single mom, and I work as a registered nurse. I have the flexibility to travel around and was looking into taking a minimum of a 2 year contract either in Hawaii (downtown Honolulu) or Guam. Upon searching for condos I noticed majority of them and what I can afford falls under Fee Simple VS Leaseholds. I understand leaseholds is basically temporary ownership of the unit but not the land itself and based on how many years is left on the lease. Say if I were to go this route is there possibility for profit and am I able to rent it out once I choose to leave for the remainder of the lease? 

I live in Arizona and have my heart set on living in the pacific temporarily. But if it is not a wise financial decision then I had planned to buy a starter home locally or a condo I can invest in with hopes to rent it out eventually before purchasing my dream home. Any guidance or advice is appreciated!
