When I look at the property and the information what I am noticing is the "game plan" is as follows:1.

If you aren't in the state to change the locks, who's monitoring the home?

However the most obvious benefit based on what you’re stating is that the depreciation from cost segregation will offset your $100k in taxable income from your commercial rental.There could be more benefits depending on future plans especially if you plan to sell any real estate in the near future.

Quote from @Dennis McNeely: In a sandwich lease option, the investor exercises their option with the property owner to purchase the property when the tenant-buyer indicates they're ready to exercise their option and purchases the property.

Some investors also use a business line of credit backed by their cash flow, which can help with future deals.If you’re planning to scale, maybe start stacking that cash for the next property or even park some in T-bills for short-term returns.
