Quang, I feel your pain and frustration, but also your desire and sense of passion.
That being said, I think what you are asking is not impossible, but it is going to be extremely difficult to attain given your present situation.
Think about it. Why would a parent or family member, much less an, "angel investor", loan you money to do a real estate deal??? What is your background or track record?
My advice would be to gain knowledge and educate yourself first.
Go to your local REIA (Real Estate Invest Association) meetings or find real estate groups on sites like LinkedIn or Meetup.com. Get to know other real estate investors and see what they are doing and what they are looking for in properties and deals. Keep it simple at first and branch out as you gain more knowledge/confidence.
There has been some good advice presented here in becoming a, "bird dog" for other investors. Being a bird dog doesn't necessarily require money, but it does require knowledge. How do you know what a good deal is? What makes a property a good investment? You need to have the answers to these basic questions before you can be an effective bird dog.
BP is a good place to start your research, but so are sites like YouTube and Google. Good luck.
