The smartest way to use it if I do (perhaps using it to put money down and they paying myself back with a refinanced mortgage in the BRRRR method).I'm also curious if the old adage "it takes money to make money" could be applied here and what I should really consider before even touching that money.

In our partnership, I’m the methodical one, I do the books, run the backend like building and implementing the company SOPs. 

Even if I don't utilize the BRRRR method or force appreciation it still looks like a better investment.

Go ahead and see if you can get them to pay using online methods.

If so, what method was effective?

Other marketing methods that I have heard of working well are looking at court documents such as foreclosure lists, divorce filings, etc.

My personal method, that makes sense for me, is doing a few flips first, to build up my capital. 

@Clayton Mobley The turn-key method is intriguing.

Yes, we're fully aware of the Dave Ramsey method to financial freedom, that's another discussion in another forum. 

I'm a new coming investor to Hudson County, and my strategy of choice is the BRR method for duplexes, triplexes, and fourplexes.I'm coming back from Active Duty Navy and i intend to sell my condo in Hawaii.
