Every hardware store has the caps, they're cheap, and nearly infinitely reusable... just toss them back in your "plumbing" toolbox when you're done.A couple of tips on replacing shutoff valves: if the existing valve inlet has a compression fitting on copper pipe, 95% of the time you can re-use the old hex nut and compression ring/ferrule/"olive". 

You realize that your investment would be zero, so your ROI is undefined (i.e. most people call this "infinite", a result you would get from dividing a number by zero.

Most real estate development projects have 200 or more individual variables that need to be assessed, and an infinite number of solutions to address problems and issues that always arise when grounding assessments of the 200+ variables. 

No matter where you live or where you own assets, I personally recommend the Series LLC to be a great tool for the individual investor who is planning to expand their operation, as it allows for you to scale infinitely for FREE- check out this article to learn more.Running without an LLC works perfectly until it doesn't - but when a lawsuit is filed you can't change your ownership structure.

When I was 25 years old I raced along every tight rope cliff edge - taking advantage of the fact that things generally go well, and while holding the view that the future was infinite.
