Placing an STR property 'in service' for depreciation

[Alan Taylor]

We're closing on a property in South Western North Carolina this coming week -- and we're trying to get the property ready to 'go live' as soon as we can.   We also wanted to be able to take advantage of the 'bonus depreciation' -- and while reading through the IRS regulations on this, for real estate, it looks like 'placing in in service' has a varying definition. 

What would be required for an STR property to be 'placed in service', for tax reasons?
