If you are looking to be easy on the eventual owner - and perhaps command a small premium in sales price - you can build a 1200 ft^2 energy efficient (lookup: Passivhaus) home, where the end-user's energy costs could be as littles as $250 - $500 per year.Capital costs to build a Passivhaus will be a little higher (10 - 20% pending on available skills and experience in your area) here in NA, but the end result is a home that is 70 - 80% more efficient than what is typically being built.

Energy start with the Argon gas or what not.So overall cost me $256 and took them about 3 hours to get it done.

Just like being an agent, there is overhead and it takes considerable time and energy to keep up on all the needed marketing, continuing education, etc.  

I am sure your youthful energy and eagerness to learn will serve you well.

I have time, energy, and drive.

When you have a single rehab going, it's probably just as inexpensive (and efficient) to hire a General Contractor who can both do the rehab and manage it. 

Think about how to become more efficient, how to do it faster, better quality at better prices. 

You'll learn as you go how to really nail down costs in advance- and you'll also assemble a team to help you get those repairs done cost effectively and efficiently (time is money).  

I'm trying to navigate around the site and find the best ways to use it efficiently and successfully.
