That gets worse as you get farther out of the cityTLDR: values depreciate, inflation has gone basically nowhere in Japan for a long time, the supply of housing is pretty good compared to demand (unlike the US) and that's because of flexibility with rezoning and development, taxes on rental income are high. 

A few things that newer investors should note:- it took 13 years to get there, you have to be patient- rents are high at about $1,750, so probably a quality neighborhood- looks like that is after vacancies, probably low turnover?

My mortgage should be about $2,100 after I get PMI eliminated and I was going to rent it to a friend that I have known since high school for $2,000 a month.

@Ming HuangRecommend you first figure out the property Class you want to invest in, THEN figure out the corresponding location to invest in.Property Class will typically dictate the Class of tenant you get, which greatly IMPACTS rental income stability and property maintenance/damage by tenants.If you apply Class A assumptions to a Class B or C purchase, your expectations won’t be met and it may be a financial disaster.If you buy/renovate a property in Class D area to Class A standards, what quality of tenant will you get?

Everything they do is quality.

The exchange must also be for like kind and quality.

Are there tools (i.e RentRedi) that you recommend using for LTR tenant screening, rent collection, background checks, etc?

It's really a good tool.

@Nick HulmeMaking improvements to your primary to make it high quality enough to rent above market rents, rent it.
