You said SRG got the best stores/locations, well wouldn't one expect then rents to be higher than even the ones advertized by 50% of SPG numbers?
no!
the thesis, through a margin of safety lens, is that SRG can undercut these inflated rent levels, release space at 17 (or 25$ a square foot if you look to projected stabilized numbers) and still make 4-5x off their rents at acquisition.
this is the worst case.
the best case is that their properties are in fact as good as Simon and Macerich on the whole, and will command quite high rents, like those already seen at San Diego, and soon to be seen at Aventura, Hicksville, Valley View and others.
but a lot of SRG value will be proven through JVs with residential sales, as seen already at Redmond and Hicksville. SRG is a different beast than Simon or Macerich or GGP. I mean, GGP was sold to BPY because they realized they were screwed and couldn't change to mixed use in a public environment.
the situation is more nuanced than just picking headline rent numbers and saying x >y.
