Investing in Southern Maine/New Hampshire Seacoast?

[Courtney Stevens]

Hello, I am new to investing and will be buying my first house hack next year (hopefully). I would love a multi family. I currently live in New Hampshire, but have been interested in buying in Southern Maine. Though I am not opposed to New Hampshire Seacoast as well. I know we are in a seller’s market right now. So demand is high and supply is low. 
What do you think will happen to the market next year? 
What are some things I can do to stand out from other buyers? Should I wait until the market corrects? Any tips on buying in Southern Maine or New Hampshire Seacoast? Which towns are the best to invest in?
