Depreciation Question (what's inclusive)?

[Jason Hill]

Hi all, I've just subscribed a few days ago and have been reading various posts and info...I must say, great source of education and inspiration.  

I have a basic question if I may...after describing 2014's scenario:

My wife and I (for 12 years now) have held 2 rental properties (our previous residences).
For these 2 properties, tax season has been relatively easy (doing them myself) because listing up basic maintenance, repairs, cleaning, etc. on a Schedule E hasn't been difficult for 2 properties.

For 2014, we successfully acquired 2 additional properties (HUD homes) for around $35k each (borrowing 75% on each), renovated 1 with around $10k and the other at around $7k. These expenses include all materials for renovations including contracted help and labor.

My question's are as follows:
For depreciation, can i simply roll up all expenses incurred (for each property) in order to ready them?  
And then, what is the typical depreciation term I should consider using (I intend to have them paid off in no more than 10 years).

Thanks for responses and any other advice you may have!
