What other kinds of loans or financing strategies are available that don't involve using too much of your own cash?

There are some that are great for sure, but I have currently heard terrible stories about people putting money in the last 2-3 years and losing it all, capital calls and losing the whole deal due to bad bridge loans (some coming do very soon). 

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?  

Do you have a significant other who could take out the loan?

Your answer needs to make sense, and be true.Also refi'ing your current primary into an investment loan also has the potential to be fraudulent if your family still occupies it as their primary. 

I want to purchase an investment condo for $150,000.I want to get Heloc loan from my other investment condo for $50,000 and use it as downtown payment for this condo.Can I get a 30 year fixed conventional loan for $100,000 and use $50,000 for down payment from heloc?

Quote from @Brandon Croucier: The loans are available but nobody wants to do them.There always seems to be something wrong with the properties, as lenders we just can't make enough $ for our time.9/10 Borrowers also complain about the "excessive fees" for the loan amount.If you are okay with paying 8k in closing costs then the loan is available. 

typically no special license is needed when doing it for hard money loans that I am aware of. there may be states like california and nevada that are tricky where lenders need a license of some sort but for most part brokers i have seen are not licensed. 14 or 15 states require state license and NMLS registration.

Is this using a 20% down, conventional or DSCR loan, although I would think a first time investor would use a conventional loan.

We are in Los Angeles, and although we do not own anything in SD, we hold a loan on a portfolio of SFR's there that is not performing at the moment.
