Can I deduct/depreciate existing furnishings in furnished LTR?

[Chris Troutman]

I am about to rent out my SFH as an LTR, and am including most of the existing furnishings in the rental. Rent is only paid as a monthly amount (no separate payment for furnishings).

A few questions:

Am I able to expense or depreciate any of the existing furniture? 

Any time constraints on age of furniture (most of it was acquired >2 years ago)?

If there is furniture for which I have no receipts, is there any other way to capture any tax benefits or reduce income from rental?

Thanks!
