@Brandon K. so many thoughts on this one being a retail specialist myself. If you're considering a 4-tenant retail development, I'll assume you've already performed a fair amount of the preliminary due diligence and evaluation such as:
* identified actual demand for the product type in the market you are considering, along with supply in process within competition area to the proposed site.
* understand current market rents for the type of tenant and construction you are considering, and at your specific location.
* understand delivery timelines, TI schedules, and general construction process/permitting for you and the end users.
* have identified the most likely tenants for the development in question, and understand the building criteria each have for spaces.
If you haven't answered "Yes" to each of the above, I would recommend pausing until you have the above nailed down. Not all retail buildings are "build it and they will come" candidates unless they are located in the most prime areas with limited to no competition. This is rare.
The way to find the above, and more specifically to answer your direct question, is to work with a broker versed in the type of product you are looking to develop. They will likely already know who is in the area, who wants to be in the area, and what other projects are in the works and further along than yours which may remove potential tenants from the conversation. They can also assist with general design requirements that various NNN retailers will want to see inside their spaces that, if known in advance, can save tens of thousands in redesign and develop costs.
Good luck and send me a connection request if you want to discuss this more!
