I am buying a Short term rental this year but will be using a property management company only for this year, which prohibits me from claiming bonus depreciation. 

Geez...there's a lot more to this than what you have so generously shared. 

I'm looking to figure out a rough estimate on the percentage that can be used for bonus depreciation if I were to purchase in this area.

And when I set a cap it is generous and I don't sweat the small stuff.

You could ask your accountant about options for bonus depreciation or possibly updating the properties in order to receive depreciation deductions or write-offs for repairs, maintenance, etc.

For years we've been selling rentals without paying anything but a small flat fee bonus to buyer Agents.

Another option to consider may be to offer referral bonuses as well to try to fill up vacancies even faster.

The mortgages and closing expense can be written off to eliminate the taxes as you want  Maybe she could also do a cost seg and take some bonus depreciation on top of all of this.

With a few affordable units to get the density bonus, we're in Complete Communities Tier 2 with a FAR of 8.0, so you could go up multiple stories. 

However, the real estate investments still offer the potential for tax-deferred growth and, under certain conditions, the ability to carry forward unused passive losses to offset future passive income.The concept of depreciation and bonus depreciation is particularly advantageous in the early years of an investment, allowing for significant upfront deductions.
