@Kiryl Ulanovich,You're on the right track:Get Pre-Approval from Hard Money Lender – Know your terms and limits upfront.Find a Deal Through a Wholesaler – Verify numbers and ensure it meets your criteria.Review the Assignment of Contract – Confirm terms, earnest money, and contingencies.Conduct Due Diligence – This includes an inspection (if allowed), verifying ARV, and rehab estimates.Submit to Hard Money Lender for Final Approval – Lender will review title, contract, and property condition.Title Search & Clear Any Issues – Ensure a clean title before closing.Close Through Title Company – Finalize funding and take ownership.Consider also lining up contractors early for a smooth transition into renovations.

There is no one size fits all answer for this question, market to market, and property to property are all different.
