Professionals make it happen

loans, insurance, title, home inspections

Realtors - work for their client and earn a commission at closing, usually paid by the Seller

Lenders - work for the bank or broker to get loan approval for the Buyer

Title Agents - work for the Buyer and are paid a fee set by law to insure the property

Home Inspectors - work for the Buyer and are paid at the time the work is done

Insurance Agents - work for the homeowner and charge an annual premium

Each of these service providers must be licensed and observe the ethical standards of their profession.  They are experts in their field because they have proven themselves to me.  I wouldn't recommend them if they were not the best.  The choice of providers is always the Buyer's choice.  Realtors can only make suggestions and mine are available to my clients for the asking.
