Are your goals even centered around cash flow?

That is far more valuable than money in my stage. 

While cash flow is important, there are several other profit centers in REI.

Everyone I've seen says "I buy houses" and they "buy" with an assignment contract, but my worst fear is if I start doing that and I still don't get a buyer, I'm going to be stuck with that house that's too expensive for me at my current stage of life.Are there clauses you can put in to wholesaling contracts that allow you an exit if you can't find a buyer? 

If you don't feel like reading the article, Amazon is opening a distribution center in Pender Commerce Park in 2023. 

Anything anyone can add would be helpful as I have 16 residential properties and partnership in a shopping center but this side of the business is brand-new to me. 

Out business is centered around selling investment properties and helping investors buy properties.

Look to stage 1, potentially even 2 properties, with those funds and maximize cash flow. 100% doable. 

At some point I'll slow down and settle down but at this stage in life I love chasing deals, flipping out of deals into bigger deals, and growing into more advanced investing strategies.
