Maybe also he checks with the school to see if there is a booster family that might be open (post COVID testing) to provide discounted housing to new teachers.
As posted, the NOVA/DC/Annapolis area is some of the most expensive RE in the US. But excellent public transportation in the DC/NOVA area so maybe won't bear the expense of a car.
Also, good on your son - hooray for teachers!
Thanks, he's been subbing since December after 27th months in the Peace Corps. He had a few contacts in that area and found out the schools are excellent. He teaches English, History and Social Studies. He Loves teaching and I believe he will make and excellent teacher
