Looking to start

[Radoslaw Wlodarczyk]

Hello,
Trying to start out investing in Denver area since this is where I live. Learning a lot recently since discovering One Rental At a Time channel. However, I'm find out that nothing will cash flow for single homes unless you put a lot of down payment. That in turn will reduce yield. Am I missing something or is that correct with current rates?
Looking at different options (multi-plex, long-term flip while renting out my current home). My current home has 3% mortgage, so it could potentially have positive cash flow. 

Any suggestions or tips would be helpful.
