Ask them how many customers they have and how many own a single property vs. many units.

I'm working with a company who owns a small, 19 unit, senior and low income apartment building.

If a guest stays for one week in July, the owner can't legally rent to another guest until August and must leave their unit vacant for three weeks.

. ;-) There is nothing false wiih what @Henry Clark said.Commercial real estate is broad - Office space, self-storage, Farm, Data centers, residential properties above 4 units, etcIt can be true that one part of commercial real estate is suffering while others is thriving.

That is smaller units built with higher density to make the numbers work for both buyers and builders.Adapting to these challenges isn’t easy, but it’s necessary to keep up with the market.What are your thoughts on how builders and developers can address affordability and supply issues. 

If it's just a two-family, or really with any amount of units, I would send the same notice to all parties so it's clear that it is addressed to everyone (even though it's because of one tenant).

If you want to put down a low down payment, you might not cash flow for a few years.And FHA for 3-4 units is almost impossible.

For example in many jurisdictions I can STR units in a duplex but cannot STR an ADU (some jurisdictions will let you STR if you owner occupy).

Small details like a handrail on stairs or window locks can cause your unit to fail an inspection, delaying the start of rent payments.

Speaking of whic, rent is due on one of my units today, and I got to log in and check right now.Hope this helps.Leon
