I get lots of such supplemental property tax bills.  

I am interested, as of right now, in either single family or multifamily investing.Currently my basic real estate investing goals are meager, supplement my current salary with passive income from rentals.

My main goal is to supplement my retirement income with $5K in passive income.  

Is there anything I can do right now or within a year to supplement my income to leave my job?

If so, you could always help supplement your income by taking on roommates; that's how I started.

What's up?
I'm currently on track to obtain my RE license and was wondering if anyone could suggest any books, videos, articles, etc. that would give me a bette grasp and more understanding on being a successful agen...

I'm not looking to replace me current company or sell it to start something new, rather supplement or diversify my income stream from multiple areas.

Value add syndicators like to refi or add supplemental loan after renovations in ~ 2 years which can increase those returns a bit but most want to show you numbers that are conservative (under promise / over deliver). 

I would of course still suggest you work a job, and use RE to supplement your salary, and slowly you'll have a point where your RE income will be able to cover all of your expenses or exceed your salary. 

Supplement that with all the things you can learn here on BP and you'll be good to go before you know it.
