The other most important factor is going to be comps in that area for similar development properties.

The human factor is essential here.... 

The other factor is that money for how long they have been a tenant needs to be in an interest bearing account so you will have to account for that...

The only relevant factor is what is the market price in that market.

The Sleeze factor is in on public post he walked back accusations, then messaged me and not only reasserted accusation but states many are messaging him in the same, and then lays out several accusations of serious nature against Mr James Wise and his operation, and the construct of his accusations is always in a passive-agressive manner, not out right stating it but laying out a series of things to infer an accusation.

@Grayson Lynum Regarding Modular, I have gone down that rabbit hole several times, and what I found it, they are not cheaper, just faster, and they look like a modular, due to the transportation limitations, the rectangle box or Prow front on mods tend to have a stigma to buyers, also many of the finishes are very low end. if you site built a very basic rectangle with the same cheap finishes most mods come with, you will be financially better off. and they are not faster, typically from order to occupancy is 6-9 months, I did my last spec in 7 mo. its just not as much work on site, the time is waiting for the factory to get to your build. good luck!
