I feel like my area the prices are somewhat high compared to what I’ve heard others talk about but then I thought perhaps it had to do with the ages of the buildings in New England.

Plus, after being a part of the club and learning so much more about corporate real estate and that side of the world compared to what most people think when they hear real estate, which is the “residential or real estate agent” assumption.

(I don't need immediate cash flow and care more about total long term returns).Relatively affordable compared to other large cities (though the same is true for  SFHs). 

The last part is a moving target, especially these days, but unless you live in a really small area you can usually find similar houses that have sold, compare how well they are fixed up and where they are, and get a pretty good idea.

Have your agent manifest sold comparables within the past 90 days to give you a sense of what the market is taking.

If there are limited comparable properties, especially direct comparable properties, this makes appraising a property more uncertain and thus places greater liability on the appraiser.  

You can then compare that to the company you mentioned and pick the best fit for you.The primary item to watch for would be prohibited transactions.

I would not personally compare it to the stock market because (among many other reasons) it is difficult to get to know the CEOs or the companies that you are investing in the stock market.

I think there's always a good reason for why the rents are lower than market including: older building, older unit interiors, the specific neighborhood or the lack of amenities in that specific property compared to other 'market rents'.

All:  How would you compare the relative security (of your investment) for a warehouse/logistics center with office space with a national tenant like OfficeMax, Staples, or similar with a NNN lease with several years left and renew options; vs. a large 100-200 unit multi-family with decent occupancy in a good area?
