I am looking to start supplementing my income with real estate.

My goal is to develop a rental portfolio to supplement my 9-5 income.

Working at a real estate company never interested me much, so I started an S-corp and used it to supplement my income from my normal day job at a Tech Studio in LA as projects popped up and came my way(mostly in the commercial field), but it was never my primary career focus.

In the long run I have a goal to work in a marketing position while saving up enough money to purchase my first rental property by the age of 25 as a source of supplemental income. 

Our reason for buying the properties was to supplement my brother-in-law's income and to help us support him...long story but it's all working out.

Awesome that you're dedicated to supplementing the pension income with cashflowing rentals. finding the sweet spot in the ownership timeline is a great idea I think.

Providing we do not have a repeat of 2008 someday you can sell it for even more than today if you keep supplementing your tenants rent in the interim and paying for repairs and vacancies out of your own pocket.     

My first goal is to supplement my current income with cash flow from rental property.

This is a large part of the reason I'm where I am today, looking to supplement, and maybe (hopefully) completely replace, my income from an 8-5 job outside of the home.

My goal is to use real estate investing as a vehicle to build a source of passive income that will supplement my retirement savings and eventually help me exit the rat race.
