You will be able to become Thane of Eastmarch and buy the House in Windhelm on Stormcloak side as soon as you made your oath.
I made this small tweak for personal use and decided to share.
This is still before of the "point of no return" in the Civil War questline and I made it no earlier just because of that and because is about becoming friend with Ulfric. Don't ask for even earlier.
Compatibility: this may be incompatible with mods changing the vanilla Eastmarch Thane quest and the house purchasing/upgrade quest. Good thing is that you can enable this one, get the dialog, buy the house, get the housecarl then disable it.
