Methodology
Last updated: 2026-10-21
Where a number appears in Sentus marketing copy, a superscript marker points to that page's Sources block, which links here for the full verification record. This page lists every external statistic we publish: who produced it, which report it came from, how it was measured, how far we think it can be stretched, and when we last checked it against the original.
How we grade a statistic
Every figure is graded before it can be used. There are two grades, and no third:
- STRONG — published by the organization that collected the data, with a methodology a reader can inspect.
- MODERATE — directionally sound, but produced by an interested party, an unaudited sample, or a synthesis of other people's benchmarks. We treat these as ranges.
A figure that cannot clear MODERATE does not go into public copy at all. Separately, we record two different things: that a link still resolves, and that a person actually opened the source and found the figure in it. Only the second earns a place in our copy. Verified figures are then re-checked on a clock — 24 months normally, 6 months for regulatory figures, which move faster. The build fails if either rule is broken, so an unverified or stale number cannot quietly go live.
Vacancy and turnover
Apartment turnover costs held steady at about $3,872, reported as nearly $4,000 per resident.
Zego, 2023 Resident Experience Management Report (2023)
The 2023 turnover-cost table totals $3,872 per resident (p. 6). The report surveyed 630 multifamily professionals managing properties with 250 or more units (p. 8). Costs vary by property and market.
Reputation and reviews
88% of consumers would use a business that replies to all of its reviews, compared to 47% who would use a business that does not respond at all.
BrightLocal, Local Consumer Review Survey 2024 (2024)
Survey of 1,141 US consumers. The 88% and 47% figures compare stated willingness to use businesses that respond to all reviews versus none; they are not property-management results.
Regulatory
32,321 fair housing complaints were received by fair housing organizations, HUD, FHAP agencies and the DOJ in 2024 — down 5.36% from 34,150 in 2023.
National Fair Housing Alliance, 2025 Fair Housing Trends Report (2025)
Counts complaints received by private fair housing organizations, HUD, FHAP agencies and the DOJ in 2024 (p. 6). Complaints are not findings of a legal violation.
Figures we are not publishing
These were considered and did not clear verification. They appear here rather than being deleted quietly, because what a company checked and rejected is part of how you judge what it does publish. None of them may be cited in Sentus copy — the build blocks it.
Multifamily vacancy reached 8.3% in Q4 2024, the highest since tracking began in 2000.

NOT FOUND 2026-08-05. Full page text (28,609 chars) has no "76%", no "24 hours", and no response-time expectation claim; it covers channel preferences and AI concierge satisfaction. Do not publish. Needs the correct source or withdrawal.
