Making ADU out of ranch daylight basement

[Michelle McConnell]

I am looking at properties in the Vancouver Wa area. There is a 4 bedroom 3 bath, ranch style home in Vancouver WA area that I would like to consider making the daylight basement into an adu (adding a kitchenette) so I can rent upper level and live in basement. I have a few questions:

1. Would doing this to basement add value to the home? 

2. The best way to go about determining the cost to add the kitchenette and if it would be worth it. For example, I would assume having contractors come to the property prior to making an offer vs after?

3. Anyone with experience in the area who could estimate what I could rent the top unit for?
