Best selling strategy advice needed. tia

Selling a 1950s 3-1 with a 2-.75 'attic conversion in Austin msa, Round Rock. Would I be better off creating an exterior door to the attic area to create a possible private entrance adu so a buyer could envision extra income? It could be easily done (adding a second door to the downstairs living room at the bottom of the stairs so it could still be one house ( maybe with double deadbolts like hotel adjoining rooms.) Or would I be better off just adding a closet to one of the upstairs rooms to be a true 5-2 house? The attic has low ceilings so it would be kids rooms upstairs...or it might make a couple of decent offices. The house about 325 sq ft up and 1400 sq ft down. The adu wouldn't be "legal" but there are a few in the area and it is an eclectic neighborhood with some relocated homes, a few mobile homes, and a couple new builds. But a 5 bedroom might generate 2k in section 8 rent. Not really sure who the buyer would be. Thanks for reading.
