Or if there's enough for cash flow, just as gracefully staying in until the option is exercised or finding another tenant-buyer if it's not.

Should I keep my license just to have this accomplishment when not exercising it?

I think BRRRR is the key here.Finally, ever since i had my daughter, i've had VERY minimal exercise.

Seattle is one of the 21 cities where renters represents at least half the total population living in households.They could vote to live for free for the rest of their lives if they wanted to.Seattle landlords--your customers are exercising their political power (or it's being exercised for them by those in power for their own purposes).The people in Seattle's government have made it into an "Illegal" sanctuary city set on harboring have-nots from other countries.When the Have-nots outnumber the Haves things like this happen.Then when things like this happen and the area's turn into slums due to inadequate cash flow, they will further plague landlords calling them slumlords and cracking down on them.This just seems like part of a much bigger political issue (and possibly a way to make their sanctuary city more attractive to who they want to draw there to live).

What a futile exercise.

I still feel great at my age that I can exercise and my cardio is great.

Here is a quick exercise you could do. 

You'll probably have to compromise on at least one of those.You may want to chat with @Jacob Thompson about his experience as he went through this exercise locally quite recently.Good luck!

I know all about hustle: I woke/wake up at 4:00 a.m. to exercise every morning, ate/eat a very healthy diet all while I worked 3 jobs during my last year of high school (2 jobs since the age of 16) and saved every penny to buy myself a car with cash and begin saving.

Tip: use the BP calculator to see what your property could do, I performed this exercise with a property I currently own and determined to keep after analyzing for rental with proper investing(already have the equity in them to do this).I am fairly new, but think positive cash flow even if very low is still cash flow, but Jim K has some solid advice.
