Dishwasher in Rental

hi everyone, i'd like to get your feedback on something i plan on renting out my studio apt in the West Village shortly and am going to be making some cosmetic updates. the kitchen is approx 8 1/2 feet x 5 1/2 feet and does NOT have a dish washer. i am considering putting in a dishwasher because I think that I could ask for more rent with a dishwasher in the kitchen QUESTION: If I put in a dish washer, do you think that I could ask for more rent (if so how much), or do you think that it's not that important to renters to have a dishwasher and to just rent out the apartment without it. thanks in advance for your feedback - len
