If a location offers incentives for moving in, it may be a sign of

Trying to meet a deadline.

Explanation:

Offering incentives for moving into a new location could be a sign that the sales/rental agency are trying to meet a deadline and are already behind.

There could be a lot of reasons for offering incentive for moving to a new location like slow business or less than ideal living conditions, etc but meeting a deadline seems the most plausible reason.

The rental/sales agency may be about to lose a percentage or commission if they're yet to find new occupants, so they could decide to hasten the process by offering incentives to potential buyers.

These incentives could be in form of a free service for a specified period of time, reduced fee, etc.
