HomePath (Fannie Mae) only requires the initial offer to be signed, all counters are done electronically through the website without rewriting paperwork each time (basically, verbal). Obviously, the final documents must be signed. Been that way since I've been a listing agent for them.
@Arianne L.
I know you're trying to be nice and I know you like this woman, but at this point I would probably have fired her. She's not following your directions and, to be honest, she sounds like she doesn't understand foreclosures in the least and most of what she told you looks like unvarnished BS. It's not her decision to make as far as repairs go. Also, you probably don't want Fannie Mae's contractors doing the work, which is what would happen. She's also wrong about the algorithm thing, there's a sales rep that looks at offers and decides on the counters/acceptances. They aren't that far on the forefront of technology.
She is, however, right about the multiple offer round. When two or more offers come into HomePath on a property, it automatically goes into a multiple offer round with a deadline for highest and best. It is all automated and verifiable, so, in spite of what I said above, I'd give her your best offer to take to Fannie Mae and ensure she doesn't add anything to it. After that, I'd drop her.
