We own a duplex rental property here in Virginia Beach and are mostly of the buy/hold mentality to supplement eventual retirement income in 6 years.

I'm engaged to be married next year and I want to supplement my job income with real estate income so that I can spend more time with my soon-to-be family.  

My long term goal is to supplement our retirement income in 20 years.

I'm currently working full-time as a Mechanical Engineer, but I want to learn about the possibilities of supplementing that income with investing.

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. 

There are also supplement loan features built into commercial financing that allow cash out once the property has been re-positioned.The most important factor is the profit per property...profit per unit is not as relevant. 

I am using a HELOC on my first duplex to help supplement me on the second property.
