What's "normal" when it comes to renters seeking apartments? It depends, of course, on the economy and what units are available at the times when numbers are analyzed. In the case of apartments needed, what's happening now is that the current rental market is stronger than its immediate past but weaker than the long-term norm of as far back as 20 years. 

RealPage Market Analytics looked at the second quarter results of this year, and they proved mixed. Absorption of the approximate 84,000 units across the country were overall positive. Perhaps, more important, is that this was the largest quarterly absorption figure since last year's first quarter when strong absorption led to a total of 84,000 units.

However, when compared with the same quarter average through the 2010s decade, the numbers look less rosy since they were 60% of those figures. Also, retention rates are down from last year's peak. Based on current absorption figures, renters are hunting for new leases according to traffic numbers, and results reflect a seasonally normal rate.
