I started off buying a house for myself. I used a realtor that was referred to me and asked him some questions that I had to get me started. The house needed some work so I did what I could and hired people (friends or referral handymen) smarter than me to do the things I didn't know how to do and I learned from them. When I found people looking to rent my house I asked a friend who had rentals about what to put in a lease and steps that needed to be taken. As I went and ran into needs I found people to meet those needs and as I found people to meet those needs better I added them to my team. I started with a realtor then added, handyman, a lender, an investor/landlord, an accountant, and an attorney. In time I build up more handymen/contractors (different ones for different needs as well as back ups) and other realtors for different areas, as well as other bankers and private investors to help with financing. As the business grows my team grows and usually out of a need for another member.
