My Accidental Roommate
The scam on the flat is a good plot device - the character's are e put in an interesting situation. Like the introduction of David as a character - adds a complication. It'll be interesting to see where the plot goes from here!

Overall I really like the story so far. You said you were new to writing and would welcome suggestions so here are my thoughts -
Proof reading - really really important. I know it's hard to spot one's own mistakes but reducing the number of errors is important.. I check sentences as I go, then I read the chapter through before I put it up then I read it again once it is posted - it is amazing how many punctuation and spelling errors I find even on the third check. As a writer you want to pull the reader into your story - as a reader the enjoyment comes from that immersion - you believe in the characters and you care about them and want to know where their story is going. If there are too many errors it jars this immersion. In Chapter 1 in the paragraph following ':Megan's Point of View ' heading I came across 'staff' should be 'stuff', 'pilling' for piling,, 'my' for me and a missing capital on Uncle. You get better and there are fewer as the story progresses.
The first few paragraphs are important in setting the scene and you do this well except unless the removers are going to feature as characters later in the story I think you have been too detailed in describing the actual moving in - I was expecting something to go wrong - a missing box - suspicious behaviour from one of the removers so it distracted me from what was the real hook - the presence of someone else and the scam. You could shorten the interaction with the removers in favour of expanding the point where Megan bumps into the person who shouldn't be there.
I think it's very promising and I hope my comments are helpful.
