In my experience in foreign countries, there is often less consumer protections/ no central MLS or licensing/ greater risk to the principals, much more red tape, and overall higher transactions costs than here so it's important to look at the whole picture not just the commish %.

For one, it's gonna help you position yourself with the value exchange.

I also noticed that tenants who are on DHS scheme usually have a higher turnover (e.g move in and out rather quick).As a foreigner, I have to rely everything on the property managers.

You've also got 30k of equity in the property that you created, which you're choosing to leave tied up in exchange for that $100/mo.

You can exchange 1 property into multiple properties in locations and any asset class (farm, office, single family, multifamily). 

From utilizing 1031 exchanges to offsetting gains with losses, the right approach can make all the difference in your investment journey.

Joint Venture: Team up with an investor who can contribute capital in exchange for a share of the profits.

Another consideration is that if you do a 1031 exchange back out of CA the state is a "claw-back" state so CA will try to get their capital gains eventually.

My exit strategy is to sell off my multi-family rentals and exchange them for single family homes in desirable neighborhoods.   

I may consider selling off my Indianapolis area SFHs to 1031 exchange to Nevada (Reno or Vegas, looking at those 2 markets) - I think my kids would rather have another home in Nevada (future primary, vacation home or rental) vs dealing with rentals 2000 miles away.
