A really simple (non-data driven) tool might be able to follow some of these general principles.

I ask only because 4 days isn't all that long to see the sights AND do REI recon. 

Now except for grocery centers that is being reversed. 70% smaller tenants and then a few small box anchors  that make up 30% of the revenue stream for the project.Lot's and lot's of layers and variables go into what a retail property is worth including location, age of building and look, parking,lighting, access to property, sight lines, traffic lights, corner or off corner, traffic counts, population levels 1,3,5 miles, median income levels, etc.

However keep in mind there is no shortage of inventory .. so don't get sucked into thinking you have to buy today other wise the deal won't be there.. there are always homes to buy that's why these companies have been around for a decade or longer.The morris tactic's frankly are just trashy the way they do things.. at least from what I have read on BP that's my personal opinion.. you have people posting that Morris showed them a house the call back 2 hours later only to have morris say its sold... this prompted them to buy the next one sight unseen for fear of losing it.. this is old school sales techiniques called the take away close. same with the scheduling phone calls so far out.. gives you this sense of scarcity.. pretty brilliant really.. these are not dumb marketers by any stretch and obviously its worked.

On their Facebook page, the latest posts are of a future residents' potluck dinner in July, and one of the principles of the development group speaking at a conference in September. 

or Will they collect 25% of monthly/quarterly/annual net profits then if/when it's sold, they will collect their principle on the exit?  

But my advice is to never loose sight of the fact that this payday may be a once in a lifetime event.

I really want to aim my sights higher though.

The other guiding principle is that in any 1031 there will be a mix of 1245 and 1250 property in every sale and purchase. 

You will likely get a price on the phone "sight unseen".
