One of the reasons gas stations (or any property types for that matter) is the buyer or borrower not knowing where all the funds will be going, aka Use of Funds or Use of Proceeds. Many borrowers do not take into account closing costs, inventory, anticipated working capital and other factors.
If a borrower is putting down a significant down payment, this is usually not an issue, or if it’s a refinance with a lower loan-to-value, again this is usually not an issue.
When you’re looking to buy, refinance or construct a gas station, convenience store or truck stop, try to have all costs in the project.
