I am curious though if the couple was a dark haired woman with a skirt and a blond-ish man both casually dressed.

The new tenant (single young woman) moves in on 8/1/19.

I actually wrote an article called the "Millionaire that greets you at Meijer" which was a story of a woman with millions in her bank account that worked at a grocery store as a greeter in retirement.

Not sure about the woman in Saitama, but my guess is there's more to the story than her just being Chinese. 

If you bawk at the $200 they charge you for a consultation, that will seem like chicken feed compared to lost rent, time and aggravation if you do not follow the lease in the process of removing them and have to start over.This is water under the bridge but may help you moving forward - did you every call this woman's previous landlord? 

Another woman showed up dressed like a Friday night out, did not look at her car till after I rented to her, big mistake.

Btw I’m a woman and out of state so, I think some assumptions are being made here ...I’ve now arranged other bids myself but this is a lot of piddly stuff, 3ish days of work.

This overdressed, overly made-up woman gets on a plane to Paris and goes and sits up in first class.

A simple background check or eviction screen would have eliminated him from consideration for me, but the woman who owned the place before me was older and just trusted what he told her. 

Literally had a conversation yesterday with a woman who has done exactly that (buy, hold, refi, buy more, repeat) in San Diego & accumulated quite the portfolio.
