I got into REI at the same time I started having babies, on top of a very busy career in IT. Talk about a stressful combination ... That was in 2010. But I stuck to my goal and reminded myself that I don't choose when great opportunities come up - but I do choose whether to pursue them. Looking back I'm extremely happy I did, now I'm in a better position than I had ever imagined.
As mentioned previously, it takes two RE cycles to become a multi-millionaire. I got the first cycle done, now preparing patiently for the second cycle.
Finding, buying and fixing houses is the toughest part. The rental stage is much easier.
To lower our stress, we limited our search region, hired a property manager, focused on nice areas with good tenants, did high quality fixes to last longer and lessen repairs, and established a relationship with a lender to simplify the mortgage process. We consistently stay away from deals we are not comfortable with, even if they are very profitable.
A few years ago my wife quit her full time job to be with the kids. She gradually learned about REI and has been helping with the admin side of it. When she goes back to work, we will pay off the loans asap.
I keep working as a self employed consultant so I can select jobs that allow a balance with family life. Most of my clients allow some work from home.
Living well below our means allows us to afford buying 2 houses a year (the challenge is to find the deals worth investing).
We don't currently live on the rental income, but we count on it for our early retirement around age 50, when we will take over its management as a part time job.
We involve our son in this process, explain to him why we have rentals, how it all works, and encourage him to think about personal economics. We DO NOT perceive college and corporate career as tickets to success, instead we teach him that true wealth and independence can be achieved through investments and starting young. Fulltime jobs help create an initial investment principal and provide for basic needs, but beyond that they can become a miserable golden cage. We teach him that investing from age 16 can help him reach FI by age 40. So we put REI for him in this context and instill it in his daily life.
