DIY or professional suggestions are both wanted.The reason I ask is because my unit leaks water when it gets really humid (thank you North jersey weather). it only happened once this year, and once last year but I'm curious if there is a general maintenance step I could be taking that could keep this from occurring.

Don't DIY it if you want to pursue it.

In Kansas, my understanding is that you have to have an electrician to tie anything into the breaker box, so you can't DIY much, if any, of this job. 

My whole real estate venture right now is so I can make it back out there someday ;)Also, your link is dead!

Honestly...turn your truck into a library and listen to podcasts...Biggerpockets, BP Money, Real Estate Guys, DIY Money, Listen Money Matters, plus so many more Real Estate Podcasts.  

My goal is to acquire buy & hold rental properties long-distance and put systems in place to manage those properties to increase my passive income to free up time allowing me more family time and time to venture into other interests.

If the numbers don't make sense, I'd definitely recommend venturing out to other locations.

I have seen many DIY or rehabs done by property owners and while the work might pass, the quality is usually **** and anyone with a "trained" eye can see the flaws.

Before you take this venture, check into the price of license renewals with the state, cost to be a member of the MLS and the cost of brokerage fees.

(I don't see managing properties in a different state than you reside in being a profitable venture, only if you have established boots on the ground.
