Assuming he needs the income, I would do it. It does not have to be forever.

I did the reverse (crash pad in DC, real home in Midwest) for about 13 months. The DC job also involved a lot of travel so when $ was the same I would have them fly me back to my actual home. Spent a lot of time on Southwest and MARC.

Stopped when I had our kid. Agree that it depends a lot on your kid’s age.
