Rehab; Costs and Estimates?4

[Quang Tran]

I've recently took my first step into real estate investing and got pre approved for a home. Im trying to break through the fear of each step of Real Estate Investing but it seems im getting lost in paralysis analysis. Ive been looking into different ways to invest such as what type of home and the well being of the home. However, how would i know what needs to be rehabbed? Would a home inspector tell me everything from the internals of the home to the cosmetics to the externals? Or would that be a contractor? 

How do i know what would drive the value of the home for some equity or how could i figure out the cost of each repair?

I guess my concern is, i could ask a contractor to see how much something would cost to repair, but what do i need repaired? Both to keep the house in good condition and drive the value of the home?
