These days real hardwood is so inexpensive to put in, I would be tempted to do that.
But just doing it for resale may not be the best use of your money.
Might be better just to add carpet and tile.
Your realtor can advise you based on the condition of your house and the competition in the neighborhood.
If you are our customer, we can get you a great deal on nail down hardwood hand scraped floors right now. About $7.75sqft installed.
Your best bet is to invite an experienced Realtor to come over and evaluate the home before you do anything. Have them check the comparables in the area and set a couple of appointments for you to see some of the homes that are currently for sale in your area. That way you learn the competition and the best and least expensive way to beat it.

If it is not quite as fancy or a lower price point there is nothing wrong with laminate as it can show very well.

Visit some other homes in the area that are on the market and see what they have. Personally, I'm not a fan of Laminate, but it has some applications that make sense. I consider laminate a short term floor whereas real hardwood is long term.
Hardwood can be refinished if ever scratched or stained. Manufactured can be "spot fixed" and laminate must be replaced.
By comparing to what is common in your area, you can make a better informed choice. Another consideration is your time left in the house. If you are preparing for the market, talk to some local agents and possibly a stager.
If you were staying long term, pick what you like best.
