Landscaping and Pest control seem cheap to me, but not knowing location, there's no way to actually know. 

Out of state wholesaler couldn't sell it for very cheap.

Cheap projects, decent appreciation. 

My question is to people who has flipped houses or know how it works, assuiming I get a house that needs some work in order to make money and resell i have to renovate it nicely but I dont have any skills nor knowledge how to do remodel and I would have to get contractors to do it for me and they are not cheap at that point i would get contractors to do everything and will i make any profit after selling the hosue? 

Owning a lot of cheap properties with crappy tenants is a great way to lose money.

If you are paying a lower than current market interest rate then don't pay it down because your debt service is cheap.

Don,  great points as usual from my cheap seats what I see coming down the pike and have personally experienced over the years in Sub to is this new crop of Guru pitching this form of acquiring real estate..

I target cheap C+ class homes because turnovers amongst this class of tenants is almost zero, and the profits are much higher.

Copper is expensive, you want to use pex (and make sure they don't buy the cheap stuff from the big box store).

However, options can probably be used to flip properties for smaller profits and less risk on a more continuous basis.Purchasing properties (hopefully) cheap, keeping them in inventory, and selling for profit when the opportunity arises is much more difficult.
