What are the negatives? 

Currently we both host 4 properties and I only own one of them and about to purchase another so we figure we better be careful and do this right. 

In my company, I only charge a fee when the property is occupied, which incentivizes me to fill them and keep them filled.

I only use insurance on single-family and not LLCs.

I only contribute the matching 5% to my 401k which is around $6,645.00 bc it's a guaranteed 100% return.

As I only use 10% of the 20-space parking lot, I'm kind of getting annoyed at the premise of paying $250-$500 out of pocket per storm, I'd rather get out there and do the work and pocket $250-$500 per storm. 

I only know of one househacker in LA who cashflows, and it's because he built an ADU.

which mind you is not as luxurious as it sounds, as where there is poverty, there is always the darkest sides of humanity, and I only know this because I came from poverty... yes, here in Hawaii... the side they don't share with you on TV and magazines... its tough here for locals sometimes, especially in markets like Hawaii where affordable housing is limited, and the normal market rents are just way too high for single income families.

Build your expectations on a higher number and, though you may hit it occasionally, you'll be overall negatively surprised.

It's in negative population growth territory but has so little new supply that it experiences strong rent growth in a lot of markets.
