My first year with a sale to claim / Tax questions

[Summer Segeleon]

So, this is my first year to claim a sale of property. I've been reading. If anyone experienced is bored, I'd love to clarify a few things, so here is my info. 

* Purchased property in Aug 2014, Sold in Feb 2015 (owned less than one year)

* I have never lived there, and I purchased it with intent to sell for profit (and did make profit)

* It was the first property i had ever purchased and / or sold. At this time, I am currently renovating another. 

SO, my questions are: 

#1 CAN I just decide on my own that i am a reseller / business, and just simply claim the darn sale, deduct the purchase price plus expenses , and be done with it, instead of messing with all of this depreciation mess? It seems there are no real rules as to who is a business and who is not? Treating it as a business seems so much easier. 

#2 Would the IRS rather I did that ?

#3 If I decide NOT to treat it as a business, and use it just for investment income/ capital gains- since i sold it within a year, I could STILL deduct the purchase price, real estate taxes, cost of materials to repair, etc, RIGHT??
