I used part of the "cash like substance" as a DP on a 10 CAP NNN where the NOI covered both the Debt service on the NNN and the interest payment on the NLD.The rest of the money (now free seed money) I reused multiple times over for flipping, adding the profits to the original seed money...expanding it to twice the original amount.Then, taking the profits and buying NNN for cash flow, while repeatedly reinvesting the  same "original seed" money to infinity...generating a continuous flow of profit to buy Cash Flow properties.Through all of this, I never spend a dime

Fill in the numbers as needed:1 - PV = $100k2 - DP = 10% = $10k3 - Fund LLC $10k4 - Offer Seller terms on $90k (int % and years)5 - Hold until cumulative CF equals DP6 - Sell LLC for 20% of appreciated PV (there's your profit)7 - Seller still has contract with LLC, but LLC has different ownership, therefor...8 - ...the New owner of LLC has exact same terms as the old owner, which means the exact same CF9 - Rinse and repeat, only you now should have twice (in seed money) what you started with, so...10 - Repeat actually means you are doubling what you started with in Step #1.11 - Repeat again when these two reach Step #6, and you double again ( now = 4 times what you started with.12 - Continue repeating every Step # 6, doubling the previous doubling, and you have your compounded return.1073741824. 

I just entered escrow selling 2 properties which are seeding my investment fund. 

It'll be 6-9 months before you get calls but start planting the seed now. 

The thought behind this was that if I can accumulate enough 'seed' money, I could start doing fix and flips; which in theory could turn that raise I passed on, into much more. 

Buy and hold doesn’t get your seed money back right away to complete the 4th R, but you will have completed your first deal. 

@Ryan Murphy, I don't see it as an advantage or disadvantage, nor would it factor into my decision from a development standpoint.If your're genuinely interested in the neighbor's lot, you might want to start planting seeds with them for that now... who's to say that they won't sell it out from underneath you should someone approach them about buying it between now and your someday?

What I'm not sure of is whether I should make a small Rental business, using the money as seed capital to secure a larger line of credit (and therefore buying more rental properties).

Plus, he probably brought weed seeds from other houses on his mower, and there was a big bermuda grass infestation.

You got to start from the seed, to get to the root, to get to the fruit.
