I generate about $25k/year in mostly-passive-income from single family rental homes. I average 20 hours/year maintaining this income stream in answering email, collecting invoices for my accountant, and making the occasional tough decision about renovating/repairing/waiting.

I got there after placing subcontractors for about 2 years with various companies, which built up the cash reserves that let me purchase the rental properties with no mortgages.

I got /there/ by inviting some young dude to a conference I organised whom I'd met at another conference. He and I worked together to match talented young programmers with companies that wanted them. Nice work if you can get it.
