This is not an exact science.

The owners who switch to a PM come to me for the same reasons Drew said above.It is not rocket science, most folks hit a point where they no longer want to trade their time for money. 

I've seen some people post on here about offering modern/classic game consoles. 

Per this NY Times article, the average American knows around 600 people.https://www.nytimes.com/2013/02/19/science/the-average-american-knows-how-many-people.html#:~:text=The%20average%20American%20knows%20about,do%20you%20know%20named%20Kevin%3FPer the US Census Bureau, the average American moves 11.7 time in their life, which based upon an approximate lifespan of 84 years, works out to be about every 7 years.https://www.census.gov/topics/population/migration/guidance/calculating-migration-expectancy.html#:~:text=Using%202007%20ACS%20data%2C%20it,one%20move%20per%20single%20yearSo, if the average American knows 600 people and they each move about every 7 years, that means that the average American knows around 85 people that move in any given year.How many of those moves do you want to be involved in?

They have to meet modern codes and SEQUA requirements.. this is what stops building on lots that would not be buildable with modern subdivisions map act standards or modern zoning. in the hilly areas road widths and slopes will not meet Sequa so they stop building on those lots there are thousands of the lots scattered around LA county and these are the lots you see going to tax sale all the time.

Modern codes might require 5 in a room like that.

It’s definitely not rocket science to do. lol

I built my first modern 7 years ago and like you agree that some (not all) moderns will age out.
