@Hsin-I Hsu  It depends on your long term goals, risk tolerance and earning potential.A couple of bay area sayings:   Any time you can afford to buy real estate you should.  

Our ultimate goal is to get into real estate development along with buying rental properties.

Hello @Sam Epperson,if my goal is to find off market leads, and I want to start with cold calling distressed owners, what exactly am I saying to them?

Know your own personality - if you are someone that succeeds in most things then a training like this can help you do it faster.

My goal is to achieve a good cash flow and rent out properties for a long time.

Having intentionality in your actions and goals set to enable you to reach that 1 real estate transaction milestone is important and will ultimately help you reach that sooner. 

The data is readily available, and I will provide the data source and its relevance.To ensure we're on the same page, the goal of real estate investing is financial freedom.

That's up to your goals and long term strategy.

My goal is to build a sustainable rental portfolio that provides great housing for tenants and solid financial returns.I’m looking for advice, insights, and connections from experienced investors or local professionals.

It's also going to be difficult to cash flow in most markets if you ARE able to put down 5% but if cash flow isn't your goal, then that's irrelevant.
