@Angeline Rebottaro, I'd recommend leaving wet wipes or cleaning supplies for guests.

Since this is going to be our first purchase, we are specifically interested in buying a four-unit (to maximize leverage through FHA), preferably on the peninsula.We have been doing research, reviewing past sales, and observing the market for about 3-4 months and understand that the supply in Portland has historically been low, so instead of only waiting for MLS listings, we decided to ask around to see if there are other ways to connect with potential sellers. 

Or the specific supply houses (Eg a roofing supply house will probably refer you to some reliable local roofers) 

Is there an over-supply of cheap housing in your area? 

Speaking of your major, I would recommend Finance or Supply Chain.

We now have 1.68 months of supply or -26.8% less listings than last year, for all residential properties in the market! 

The fact that we have almost no supply, particularly in the lower price points, that's the story here. 

If the key to fighting COVID-19 virus, is pure water, used to wash it away; then only certain parts of the U.S. still have pure water supplies, to be used in combatting this virus.

As far as macro economic risks go, inflation is the by far the biggest one in the next 1-3 years for the general population, and will hit the purchasing power of our seniors particularly hard as they disproportionately hold bonds, CDs, and cash.Take a look at the M2 money supply curve over the past few years and you'll notice a trend with 2020. 

Someone I know also told me a trick to finding good contractors: Go to the local specialty supply houses like plumbing, electrical, etc.
