Social Media - Millennials will use social media and the internet to do research on the home they are buying as well as anything else. Make sure you find a realtor that knows how to use social media for that advantage.
Respond Quickly - Instant gratification is something a millennial wants, so make sure you or your agent responds quickly to their questions about your property before they move on to the next thing.
Be a Resource - First time homebuyers need a lot of information when they are shopping. Be a wealth of knowledge about your neighborhood, the community and make sure your Realtor is as well to keep them informed of all the steps there are in buying a home and that he/she has other outside resources.
Photo Quality - Since a mobile device might be the way someone sees your home for the first time, your photos need to be great.
Sell DIY Projects - Millennials grew up with HGTV and YouTube so they are comfortable with taking on a few projects. You don't have to have every little thing done, because they are also mindful of adding touches to increase the value on a home.
Outdoor Spaces - This is more important to millennials than having a huge home, because they enjoy hanging out with friends and having good experiences. Play close attention to your outdoor spaces and make the most of them when you market your home.
