Best of luck and don't lose that energy!

I really need help here; I would like to paint everything, replace most of flooring (not the hardwood upstairs) to fake wood, and tidy up some of the ugly light fittings/fans.

When you know what someone wants and giving them what they want gets you what you want principals are a foolish waste of energy.

Time and energy are valuable commodities so if you don't have the desire to do hands-on rehab work or manage properties, vet tenants, handle maintenance issues etc, then self-managing or flipping may not be for you.

Hi,I'm a new member from Texas who is currently employed in the energy industry.

They have the money, but don't have the time and energy to waste.  

But if you go that route, then you are negating so much of what makes investing in real estate profitable, and at that rate, why not just invest in some high dividend energy stocks and be done with it? 

I specialize in healthy, energy efficient homes.

Lastly, I am well aware of how important ones time and energy is.

Matt laid out the costs and expectations for you, so it will come down to how much time, energy, and resources you'll have for your real estate job.
