I agree with Susie Kay, there is just no way to know a conservative cost without having a construction gm or foreman walk the property and submit a bid. Then, there is the question of...is this property for you to live in or an investment flip/flip and hold? These repair costs will be different based on finishes and such that may be necessary for you but not if flipping to sell or flipping to hold/lease. In any event, connect yourself with a local Realtor. They can be your boots on the ground by finding you a home and having a team of vendors that can submit bids on the repairs. Good luck!
