Eventually I figured out that if I sunk all of my cash into properties, I wouldn't be able to buy any more for a long time and starting using some leverage.

I have been an agent for 35 years and started my investing career many years ago and am amazed that so few agents take advantage of the leverage and opportunities we have over others to build wealth and passive income. 

Quote from @Chris Seveney: I completely agree with your point about not over-leveraging and keeping some equity in the deal.

HI @Zachary Sakena putting property into LLC in my opinion depends on that strategy you are looking to implement for next property and if you want to leverage property moving out of into LLC.  

You can leverage your HELOC and cash to cover the down payment, the initial rehab draws, and holding costs. 

Your idea of investing in a condo at Palms Place or Trump properties could be lucrative if you focus on leveraging the high demand for vacation stays.

Depends on really what you are looking for:-Speed - some HMLS can go "no appraisal" so can close very quickly and beat cash offers if you are in a competitive market to buy-Interest Rates - can range anywhere from around 8% to 13% (same with "points") but not usually as huge of a concern for flippers since the terms are so short-Leverage - depending on your risk appetite / capital - this is also a top concern for some (almost always over and above rates/fees) can see anywhere from around 80% LTC to even mid 90s LTC (including 100% of rehab budget)

Stay adaptable and be prepared to adjust your strategy as needed.By leveraging these strategies and resources, you can effectively scale your real estate portfolio using the BRRRR method and achieve your investment goals.

Meaning the folks sitting at sub 25%, probably 20% DTI with cash still on hand to buy properties but choose to leverage.

It's not going to be the best investment, but it probably won't be that bad either (with the leverage of the mortgage it will probably outperform my stock index funds).
