I would suggest coming to some investing meet ups and just start talking to others and form a plan based off of that.

I'd be happy to provide some recommendations and suggestions for your situation as a foreign citizen living in Miami.First, it's important to have a good understanding of the local real estate market, including pricing trends and neighborhood dynamics.

As you suggest lowering down payment to buy more properties is one way, although the downside is greater risk in event of down cycle and more time to manage required.  

I would suggest doing these separately however since you will run into issues with a partial release clause on a blanket loan.

Make offers, then when someone says they will consider Creative Finance, that's when you make the suggestion.

Any suggestions for this? 

I get to invest alongside experienced institutional investors and a bunch of other retail investors.

Off market deals I say are not really the bread and butter of most retail agents. 

I HIGHLY suggest you connect with a local expert such as @Josh Green.

I suggested waiving the entire first month but our manager suggested we wait to see what happens with 50% off first.
