In full disclosure, the travel agency is part of a multi-level marketing establishment so I am making some money in it but it's simply supplemental income that I use as play money as opposed to anything that I think will be replacing my W2 income anytime in the immediate future but it has let me connect with travelers and agents that I could use for my own travel.

My tax return shows my W2 and then has a separate section for supplemental income which shows the gross rents but there is no place for total income as far as I can see.

To supplement that, there should be additional self-paced study opportunities in addition to free and cost-to-you live virtual training.

So much so that I am considering a foray in to property management to supplement my investing. 

My current plan for a couple rentals I've picked up over the years is to have them paid off by the time I'm around 60 years old, and have it be a supplemental revenue stream in retirement.

My vision is to have 10 sfh properties, to supplement our retirement investments (stocks and bonds).  

I also have an umbrella policy as supplemental coverage. 

So I am basically saying to listen to the free videos and then supplement your learning on BP.  

My HELOC will help supplement financing costs, and rehabs in the event the HM isn't favorable.

The supplemental bill was over $7000!
