However, each case has different issues, and you should allow your investigation of a specific property to influence your decision.
Your first step should be to find financing. Commercial lenders and the types of loans they offer differ from conventional home loans. They can be better in some ways. Commercial loans require a larger down payment, but you can avoid personal liability if the deal goes bad, and the bank won't mind as much about you borrowing money for the down payment from friends and family.
When thinking about financing for properties of a commercial nature, make sure that you are using a top grade lawyer who goes over everything side by side with you. If something goes south in your property adventures, you'll want the best lawyer working on your side.
