How much value does new appliances add to a 2-4 multifamily?

[Andrew Michaud]

I am purchasing a 3 unit apartment, all with outdated appliances. I am trying to set myself up for the most efficient appreciation before I plan to refinance and put that money towards another property. Is there a rough estimate on what a new appliance is worth on appraisal? I plan to print off a retail value sheet for every appliance in hopes that it will help the appraiser make better judgement on the value of each appliance.
