I live in a detached house that I purchased with a loan.

Thanks to this, the significance of my life these days is (1) paying off my mortgage and (2) securing child support for my children -- similar to many Japanese (right?).

I, initially, was against the purchase of a detached house. In all likelihood, it would be inefficient.

The property value of a detached house's building (x land) portion is roughly halved in 10 years.

If the property is 40 years old, it will be 6.25% of the initial amount; if it is over 50, the property value will be almost zero.

It is similar to land.

Any land also has a life cycle, and land with few new tenants is valuable, but its value declines.

In this case, it would be something called 'psychological value,' which differs from market price.

"Who would want to move to a conservative, exclusive land run by old-timers?"

It's worse if you have a community association president (often an old geezer) in your area who is not very smart.

Preparing for summer festivals, cleaning up local temples and shrines, and cleaning up the neighborhood (well, I guess this is necessary), it's nothing short of a hassle.

The neighborhood association board will be tasked with electing the following board members.

People in the town can play the final card: 'If I have to serve on the board, I will leave the community association. And they have done so.

(To do this year, I prepared a report on how to "plan for the next 20 years so that everyone can make a "fair" sacrifice" and went around to persuade the residents.)

Still, the reason I haven't withdrawn from the neighborhood association is for my research.

If you are interested, please see my recent column.

But that's beside the point.

Recently, I am glad that I forced myself to build a house -- because I am beginning to see the social problem of older adults being denied renewal of their lease contracts.

It is risky for a lender to rent a residence to an older adult who lives alone.

This is because older adults who die alone may become decomposing, sludgy bodies and have their real estate turned into accidental property.

Thus, a "reluctance to lend" to older people will occur.

I am also an older person, so I understand the borrowers' screams and the lenders' worries tremendously.

Another reason I'm glad we built a single-family home,

"I can play with my home as a toy."

Well, a lot is going on, but specifically, here is what I mean.
