We also lend them our VIP discounts for HVAC, plumbing, etc.. as well as supply stores.

This also ensures you get your money back in full but could also benefit from the profit.Of course you could do a combination of the two (anything in between) where you still charge interest on your loan AND you share in the profits.The way you craft the financials is totally up to you guys and what you feel comfortable doing.Hopefully that helps. 

@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.
