What are your thoughts and which city would you choose?

Leave the owners alone, when and if they are ready to sell, they will, and there will be plenty of lots to choose from on the MLS.I have no statistics to back this up, but in my casual observation after our fire is about 1/3 of the owners rebuilt their homes (some built similar, some duplicated exactly--big mistake, and some built better/nicer/larger homes). 

I have owned so many properties in NY that were long-term rentals and it is renter-friendly, but if you choose correctly, you won't really ever care.Meetups are a great way to add to podcasts and books.

When most US investors are faced with the prospect of converting (lots of) USD to JPY, to buy properties in cash, that in depreciate in value (when contemplating resale) and face decreasing rents over time... you need something else to justify choosing Japan over the US.

Whether you choose to run screening before you show the unit to them is a personal choice. 

You'll likely have to have your name on title for six months before you can refinance the property.This way, your spouse can pick and choose the type of finishes that your spouse would like and then when you're done finishing the rehab in six months you can get the home refinanced and pay your family member or friend a couple thousand dollars for their willingness to be on the loan.  

Question: why would one choose to build an ADU when existing structures sell for less than the cost of development?

This comes from several data points, the first being the average age at which people are choosing to stop renting and buy their first home.

I was raised in the land business and sold land exclusively for many years.

A lot of major companies are choosing to build and develop here (Intel, Meta, Amazon, Google, etc.) so the population and job market are also growing.
