This would save you from having to buy lists, do mailings, field calls from potential sellers, negotiate, etc..

IN my case the women were much better negotiating and closing than the  men the men were there for safety.. this is just reality of the day.. not sexist.. 

I can see it from his perspective of going from paying $0 in rent to paying $X is rough, but I certainly don't want to get into a negotiation after closing with the son.My question is - I got the inspection back and plan on making some requests anyways -  should I / can I require that I have a signed lease from the son before closing?

Don't be afraid to negotiate!

You can ask the owner to give notice to some or all of the tenants during the inspection contingency negotiations.

If nothing else, an inspection report is a negotiating tool.

Expect that anything you tell them they'll tell the owner (which could affect your negotiating position).

I know he's open to negotiation but at this point my eyes are starting to cross running the numbers over and over again while changing the variables. 

It's up to that seller to offer to pay whatever he wants and if that buyers realtor didn't have to split with a sellers realtor he'd have likely done it for 2-3%People act like this stuff is set in stone and there is no negotiating.
