Estoppel letters are definitely something I would recommend for commercial properties.

Any book recommendations will be very much appreciated. :) Hi @David Gotsill, @Tom Wong, @Benjamin JonesI am in Kanto and investing in Hokkaido.Agree with the comments PR and language are barriers to entry.

With respect to AJ, he is a good friend of mine and I highly recommend him too.

We don’t know any PMCs to recommend in the area mentioned, but since selecting the wrong PMC is usually more harmful than selecting a bad tenant, you might want to read our series about “How to Screen a PMC Better than a Tenant”:https://www.biggerpockets.com/member-blogs/3094/91877-how-to-screen-a-pmc-better-than-a-tenant-part-1-services-and-processesWe recommend you get management contracts from several PMCs and compare the services they cover and, more importantly, what they each DO NOT cover.

Could you please recommend any local real estate agents?

If you are new and don't have a clue, then I would certainly recommend them or some company that can guide you through things until you have an understanding. 

@Pat Aboukhaled can you recommend one of those investor meetups that you think would be good for a newbie like me?

If I have some cash do you recommend clearing the loan or invest instead for next property with proper planning ? 

Highly recommend (I require) collecting first month's rent prior to handing over keys.

My recommendation:  Punt.
