Mr. A will move in by the end of this year

The person in front of my house passed away last year.
The site of that person’s house is large, about 700 square meters.
The house they lived in was demolished.
Four homes will be built there.
Contractors are currently working on the residential land.

According to the real estate agent, my neighbor Mr. A is moving in.
At the earliest, the house will be completed and Mr. A will move in by the end of this year.
