Self Storage Expense Projections - Climate Controlled

[Veeno Suchdeve]

Hello all, 

I am working on my first warehouse site to convert to self storage and have been on youtube and learning about this asset class.  I'm having a bit of difficulty putting together a list of monthly expenses that I should account for for a climate controlled site. 

For now I'm using 35% expense ratio to move forward and now the deal is getting more evolved and I feel I need line items for expenses and not just a %. 

For now, I have taxes, insurance, utilities, & management for my expenses.  I understand climate controlled sites don't use the same amount of energy as MF sites do.  Are there expenses that I am missing here? I will have the site fully automated so I don't think I will have someone onsite but will have someone answering incoming calls.

I appreciate any feedback or support in advance.  

Regards,
