After paying a competitive rate for the property management and ASSET management that the small operator does himself.  

When I contacted MFM, they told me to direct my complaints to Prime as they operate independently of them.

Nothing wrong with LTR's - but what I like most about STR's is you are (usually) operating in better appreciating submarkets. 

I operate out in Southern California.

They usually sell for a really attractive price because investment property financing is (obviously) difficult, somewhat limiting the buyer pool to owner-operator small business owners (who in turn are typically great clients, as well).  

Pick solid operators and solid asset classes.We syndicate self-storage projects.

A good rule of thumb is to keep 3-6 months of operating expenses in your rental account as a cushion.Once you’ve got that covered, you can start investing the excess.

If there is no debt service probably 30% is still going of the rent is still going to operating expenses which means that you only made about 480k or so. 480k rents + 800k property is the same 1.3million roughly.

I am curious to learn how these operations are managed from abroad.From what I've seen, it's 100% possible to invest in real estate in the United States remotely.

But I’d be amiss if I did not suggest that instead you gain knowledge of the aforementioned 3 foundation by studying for a real estate agent/broker license, and then seek employment with REITs, real estate operating companies, real estate managers, or real estate brokers.
