Keeping your cash flow separate is smart, but you might as well make that money work for you.I’d look into a high-yield savings account or money market account—at least you’ll earn some interest while keeping it accessible.

It normally doesn't cost you any money to open and to be able to access that large amount of equity to buy or stabalize your current portfolio allows you so much more opportunity costs.For instance, I took a $200K LOC out on my primary residence when I first started in real estate.

But the places we all encounter that could only have a wheelchair ramp put in that intrudes into the public sidewalk (which neither the landlord nor the tenant owns, and now the sidewalk may not be sufficiently wide or accessible for a wheelchair), or that would require tearing down the storefront's façade (envision a storefront right up against the sidewalk), are grandfathered in. 

Cameras are motion-activated, can give you alerts, you can record the video and access it from anywhere, etc.
