Breezehome key not being awarded

[banjo2E]

I have become Thane of Whiterun and have 5000 gold, and when I tell Proventus Avenicci this he says "Wonderful! Here's the key to your new home"...except no key is given to me, no gold is deducted from my wallet, and his conversation option for house buying remains available and acts as though I said I wanted to wait instead of purchase.

 

Presumably this is mod-related, since it never happened in any previous playthrough...except I tried disabling every single mod short of the core game/DLC and the racial skill / perk tree altering mods that I wouldn't be able to disable without breaking things and it still kept happening. At this point I thought maybe it was because I'd cleaned my DLC masters with TES5Edit and that had broken things somehow, so I swapped those out for the original masters...and I still can't buy my house.

 

I'm at my wits' end trying to figure this out. Any help at all would be appreciated.
