Buying and want to estimate the repair costs

[Mao Pmn]

I have a property that I manage and the owner is preparing for a deed in leiu. I might make a move to purchase it, can any one help me with a strategy to gets estimates on total repairs or unseen issues. As a property manager I haven't seen any obvious major issues but I need a look over similar to a inspection or appraisal. General Contrators, Inspectors, Plumping, Electric, Foundation, etc. What is the best plan?
