- Are there State level taxes that need to be paid, if so when and how often?

Geographic/state-level shifts? 

Setting up a MLS listing (although one with certain criteria - requires a concierge level service) is minimal time; but driving to see property (DFW is not a small city) takes time with pre-research, scheduling time with you, post-research, etc.

Looking for some reliable contractors to do some fixer uppers in the north shore area, any suggestions?

We have achieved our current level of income very recently, within the last few months - we were making pretty much just enough to pay our debts before that.Now that we have a bit more disposable income, I started looking around at different investment vehicles for retirement about a month ago with the goal of retiring by age 40 (in 12 years).

This is based on my comfort level and previous experience working on properties.

Or as an alternative, just letting a professional handle leveling the floor and putting LVP down.

Factors like these will show the level of confidence people have in buy and hold real estate in your market. 

On your first one don't get to into a fixer upper unless you've got twice the time and twice the money needed and talented free labour.  

@Evan Leibovitz This is a highly personal question as it will ultimately come down to what level of risk you are willing to take on and what inconveniences you are willing to tolerate.
