Now, I am up for bigger challenge.

Now, in my dotage(I'm 44;) I look at the portfolio and can clearly see that the theoretically lower cap rate properties have been substantial outperformers over the years on the metric of cash flow- so I'm pruning the challenging(and capturing the principal appreciation, *wink wink*) to replace it with the chill. 

@Joe Villeneuve just the general insecurities that come with the nature of RE investing.  

Pretty cool if you have other employees who are starting out... not really necessary if you Cold call people Alot ( I say this because if you cold-call often, naturally, you'll pretty much have your Pitches down-packed .Contact me anytime  and i'll gladly share some knowledge with you. 

Monitors are not bad (propane or ng) but keep in mind ... with any "single source" heating idea, there will be challenges (one room cold, the other too hot, etc.) -- You mentioned propane.

Only challenge is my business hasn’t been established for a full two years yet.

You need appreciation, both forced and natural to make up for the 40 year rehab cycle. 

I have a general idea of what I'm looking for, but coming up with a potent goal is challenging for me.

It's been a challenge getting him in on the duplex plan. 

It's free and clear so by nature it is cash flowing.
