A lender's process happens to double as a safety check for the buyer: an appraisal, a title search and a required inspection on some insured mortgages all surface issues before you are committed. A cash buyer who skips those steps to close faster is removing the checks, not just the paperwork, and takes on that risk personally.
Budget for a home inspection in the $400 to $600 range regardless of how you are paying, and expect legal fees in the $800 to $1,500 range for the lawyer who handles your title search and closing.
Cash buys you speed, not certainty. Certainty still comes from doing the checks. Get your hand-reviewed valuation from Joel Dyck.
