"patience" is highly desirable trait when investing, but one of the harder ones to master - particularly at 22.Determining cash flow of an operational property is a relatively straight forward exercise of first determining your net income by deducting all operating expenses from revenues.  

At the end of my years of course I would want all B class and A class properties as I am sure I will have less energy to deal with headaches, maintenance issues etc. and I may be thinking to exercise my exit strategy but who knows.

So I had an instant positive cash flow.Next, the option price was for the mortgage balance at the time of purchase. 18 months later I exercised for 25% under market value.

This free exercise isn't paying da bills ;-) Thanks for working so hard on it.

Example: “buyer does not have to exercise a balloon payment unless the appraisal is 25% more than the current loan balance.”

While many investors have 10-20 properties, many which are not paid off, the bank do have the right to exercise the due on sale close and bye bye properties.Better strategy is to get 10 BRRRR properties max that way you reach your conventional loan limit and try to pay them all off ASAP.Just imaging 10 payoff properties and some being multi, that cash flow is sweet.I will stop at 10 and then go to developing.

And as you said, a savvy investor might be willing to acquire and exercise the owner's redemption rights.

I also plan on either increasing the rents over time due to the legal allowable limit of increases in the area, or exercise the option to not renew the lease and budget for a rehab of the property to get it rent ready.

I have seen deals where the purchase is contingent on the tenant (Walgreens in your case) exercising it's renewal option.

@Darrell Shepherd it does appear that most banks don't exercise their "due on sale" clause.
