I have one right now 117 acres that i have a lease option to buy.. the owner though in contract allowed me to sub lease the grass seed farming. 

So I'm wanting to grow the business in a way that does give me seeds of proof that things are working, knowing I'm doing the best I can, whether it ends up happening quickly or not.

Essentially, If you can find and rehab a place for 70% of the ARV, you can refinance it and redeploy your seed money over and over again.

Your cash is your seed money. 

(huuuuuu...that's me taking a breath)... and fully knowing why you should never, ever, spend your "seed money...only your profits", and why that is so important to the differences between spending and using money, owning and controlling assets, thinking like a homeowner vs. a REI, analyzing using the stock market formulas vs. not, and why all of this together (and more) is the..."

so for now its a grass seed farm when it ripens it will be a 50 million dollar property..  

Real estate is  easier if you have some cash of your own to work with as seed capital. 

For someone in their late 20's who is fairly responsible (full match from 401k, regular small contributions to a taxable index mutual fund, and occasionally purchases of individual dividend stocks) 12% worth of gross pay including employer match another 20% going to savings (no real housing expense at the moment, just covering certain smaller expenses for the folks)Do you think that seed capital for an all-cash out of state BRRR investing is more beneficial than say putting a downpayment for an affordable co-op in NYC to live instead of paying rent?

Use it like your seed money. 

Equity in the area was very high and we wanted to capitalize on that to get seed money for furter real estate investments.
