re: Sell as is or do some improvements?

As a few others have mentioned, bathrooms and kitchens are the only major items that generally get you any return or even break even. And those take time so probably not a good idea if you are trying to get in the market before interest rates slow it to a crawl.

Small items that can payoff, paint. Generally neutral colors and white.

If you are using a realtor, they may put you in touch with a staging person who will walk through with you to suggest some changes that make the house more appealing. They will probably make several suggestions that are cheap to implement and create a visually appealing look.
