Upon meeting my primary-residence requirement to secure the favorable financing, my goal is to use this property as a launching pad (no pun intended) for starting a location independent lifestyle, while having a home base to return to whenever I want to take a break from traveling and living abroad.Expecting to close in early March.

Most people never even do that.Start learning about financial independence.

I am not trying to add a separate rental unit  - the rooms will be rented independently to local students or young professionals, and will have access to the upstairs full kitchen.

My wife and I are 29 year old physical therapists who are seeking financial independence and an escape from the 9-5.

What are the things you suggest a remote investor do independently?

I want to live independently and move out of both of my parents homes, however, I don't want to make a potential financial mistake.

I would recommend contracting an independent agent(s) that work with multiple companies. 

What it appraises for and what it costs to build are independent of each other.

If you are not dealing with an Independent Agent (who represents multiple carriers) you may want to get quotes.  

I highly recommend and independent agent especially when you're looking at investment property.
