Deducts on investment properties with no income stream

[Ray Slack]

I Purchased a few pieces of raw land and also a few very run down houses that I plan to not renovate for the next couple of years. (They will just sit) 

So, both the land and uninhabitable homes are not going to be be rented or available for rent for the next few years.  Do I deduct expenses such as utilities, landscaping and property taxes annually or just add those expenses to the basis when I sell?
