Another element is asking if they buyer has driven by the property?  

Know of any podcasts here on BP that make mention to the storage element? I

This time it's still an "ad value", however, the new element is this commercial unit attached, and two of the 4 apartments will be delivered vacant.

That's not a term I've heard before.I think the "pressure" element is not relevant.  

The human element is that you are providing a safe, clean affordable apartment for the ability to earn money. 

The interesting element is that appreciation has been brisk and that raises some questions, like do I shift my portfolio to a lower price area and get more properties, do nothing and keep collecting cash, or sell a couple and redeploy into higher yield properties and/or lower tax/insurance areas.

Currently prices are low , interest rates are at an all time low and affordability has never been better but the missing element is confidence .Until the jobs come back there will be no recovery in the real estate market.

From deals falling through with private sellers, to spotting techniques that were used on me on wholesale fees, and even one seller choosing another investor over me, after giving me the ok, even when I made a hire offer, and now recognizing the technique that investor used to price condition the seller.I've read Ziglar's Secrets and was starting on Dan Kennedy's Sales Success but this book adds non-dispensible element I that needs to be added.

Remember that 1031 is only for the tax savings, but still an important element. I

There is still a seedy element (I caught my soon to be neighbors stealing electricity and water from the house), but it's getting in line.
