Crack on the wall to wall intersection

I was planning to buy a house in Secaucus and its a townhome. In the master bedroom, I saw a crack in one corner (wall to wall) which runs from the ceiling till the floor. The Inspector who inspected the house said that its because the house is moving (as the whole community was built in a swamp area) and its definitely not an issue at all. But I wanted to get a second opinion. Please advise.

It’s tough to tell much of anything without pictures and measurements.

If it’s a hairline crack there isn’t much to get excited about.

Yes there is some movement but the question is how much and over what time span?

We need more info as stated above. Pictures etc…
