Why don't you have an office?
To conduct a real estate brokerage business, you need a telephone, computer, Internet connection, printer, copier, fax machine, scanner, camera, and that's basically it.
When I started my own company, I wanted to have a lean, low-overhead operation. By doing business out of my home, I eliminated typical operating costs of brokers such as a mortgage payment or rent for a building, utility payments, insurance, maintenance, secretary, and the other expenses the average broker has.
I already had the above named equipment when I started. Occasionally I have to buy some copy paper and ink cartridges.
Customers who come to my home can sit at my dining table and sign papers. It works, and it saves money. That's how I can offer full service at less cost to you. Please ask me about my business policies, and read my comments addressed to Sellers and Buyers on my home page.
