Miami Condo - Features to seek out?

[John Stamos]

I am looking to buy a condo in Miami as an investment. What features in a condo make it more valuable and a better investment over time? For example someone told me to go for a higher floor in the building if possible because it gives better views and is more desirable. Or high ceilings, water view balcony, closer to beach etc. Some say buy away from the water due to rising water levels. My friend feels higher pedastal unit ceiling (Lower levels with poor balcony view) is more desirable whereas I feel a regular ceiling with a water view balcony is more valuable (higher levels in the building) - what do you guys think is nore valuable between those two? Needed some advice on condo features to seek out when picking between the various condos. Plan will be to rent it 6 months and use it as a second home for 6 months. Looking for a short list of features that make a condo appreciate over time! Thank you!
