Vacancy reporting becomes actionable when the clock has a clear start and stop. A unit awaiting repairs is not the same as a market-ready unit with no qualified applicant, even if both appear as vacant in a portfolio summary.
Quick Overview
Track possession date, make-ready start, ready date, listing date, first inquiry, application date, approval date, and lease start. Report unavailable, make-ready, marketing, and lease-start gaps separately. The turn-ready date reliability research is a useful companion control.
Measurement method
Use the vacancy follow-up signals to assign a next action to every active listing. Compare local asking-rent evidence with signed lease outcomes; national vacancy statistics are context, not a pricing instruction. Preserve concessions and listing changes so a shorter apparent vacancy cannot hide a demand problem.
Common Mistakes
Do not start the market clock before the unit is legally and operationally ready. Do not treat an inquiry as an applicant. Do not compare a single-family unit with a multifamily market series without documenting the denominator.
Research notes
The Census housing vacancy definitions distinguish vacancy categories. The Census HVS provides national estimates. The ACS housing documentation explains survey context. The HUD Fair Market Rent program documents a benchmark rather than a listing price. The BLS CPI housing measures explain rent-index timing. The FHFA house-price index is a sale-price measure, not rent. The BLS labor data can inform local demand context. The Census building permits survey tracks permitted supply. The Census housing completions survey tracks completions. The HUD User PD&R data page provides additional housing datasets.
Common Questions Answered
Which date starts vacancy?
Use the first date the unit is both available for lease and operationally ready, and retain the earlier make-ready interval separately.
Is a national vacancy rate enough?
No. It is a comparison point; unit decisions need local listings, signed outcomes, and documented property constraints.
