New to the site. Need advise

[Luis Ascencio]

Good evening friends

My name is Luis and I’m new to these forums. I live in Los Angeles county and would like to enter the real estate market. I have been an entrepreneur for most of my life. I currently have a business that deals with home improvement products. I am a licensed contractor. I am 39 years old and will be 40 this year. I am starting to plan on retirement at 55-60 years old. Could you guys point me out in the right direction. I would like to creat passive income for retirement. I have all my capital tied up in my most recent business that I started 2 years ago. I can do rehabs as a start if that makes sense. I have no clue on the real estate industry. Your advise is greatly appreciated.
