I asked her to pick the paint colors. 

During the height of the worst real estate recession in the last 100 years, large multifamily had the lower mortgage delinquency rate out of all real estate subclasses (0.4% MF vs. 4.0% SFH) so yes, the syndication model (which is just a generic term for raising investor capital and is nothing new) absolutely was tested and passed with flying colors.

If you think that this plan "essentially guarantees cash flow every month" they you need to take off those rose colored glasses.

Plus, you can always upgrade your bedding to include luxurious fabrics and colors that will make your room feel even more special.

After placing food coloring in the upstairs toilet it appears there is a leak.

I use them at home as well. https://www.costco.com/henckel...Ours are the lighter colored versions from when they first came out.

I watch them only to see what finishes and colors are popular, lol.

Google how to check for a leaky toilet, but you simply need to put food coloring in the top of the toilet and if it feeds down to the bowl in 10-15 minutes, the toilet is leaking water and needs to be fixed or replaced.

Good, low-risk starter opportunity or do I have rose-colored glasses on?

You probably don't need hospital grade, and if you don't know what "isolated ground" means or why you would want it, don't buy one.If you know you will be replacing a lot of receptacles of the same color, most home improvement stores have 10-packs with better pricing.
