Families with children are not cramming into 1 and 2 bedroom condos in DC for the schools. 

For example a single mother with 2 kids and a bf may want the bf to be an occupant in case things don't work out she can make him leave and maintain a stable living situation for her children.

Look at the space requirements for children in foster care.

I wouldn’t even want to share a house with friends or family members unless it’s my wife or children. 

I would maybe ask the person sending these emails (if through the meditator or not) if there was a particular instance that they were upset about that you could resolve - did they have too much to drink maybe and tromped through  her flower garden, were they excessively loud and kept her young children awake etc. - is there a resolvable issue you can fix to appease her until you get these last bookings through? 

Most families would never sell off the ground around their house; and would say let their children deal with that. 

(remember when landlords used to have a "no children" policy?

Our family has grown and our children would have to change schools if we moved to the condo.

Tenants can be like children who will try to get away with anything they can when there's a substitute teacher.

I am approaching 30 and have 2 small children, a 2 year old and a 2 month old.
