I did not attend the 3 day class, but purchased the self paced virtual version with the mind set that even if I only learned the how, it would be worth the spend long term.

House hack another property with a low down payment loan and use the remainder or the proceeds to either renovate or purchase another investment property?  

You start with a purchase and sale agreement and reduce everything to writing.

For path #2, you mean purchase & renovate a 3-5 unit building right?

Quote from @Jarrod Ochsenbein: I purchased an existing Padsplit with a DSCR loan. 

Once I get better at purchasing and adding to my portfolio, I know I will have the knowledge to be able to survive without needing the benefits of cost segregation.

Or explore a 40B lottery condo purchase and look into house-hacking.

Purchase Price:Focus on areas where the rental rates align well with your purchase price.

Both properties have a substantial amount of equity that’s essentially sitting idle.Would it be a good idea to tap into this equity (through a HELOC, cash-out refinance, etc.) to fund future fix-and-flip projects or purchase additional rental properties?

Because I had already purchased  the house building courses I got a nice  discount  on thw course I wanted.
