What missed calls actually cost a 200-unit property manager
The arithmetic behind unanswered leasing calls: how 30 inquiries a month becomes three lost leases, with every benchmark sourced.
Every property manager knows they miss calls. Almost none of them know what it costs, because the loss never shows up on a statement. There is no line item called "the person who called at 7:40pm and leased somewhere else." So here is the arithmetic, with every input sourced, for a 200-unit portfolio.
Start with the missed-call rate
Over 60% of calls to multifamily properties go unanswered. That figure surprises people, so it is worth sitting with: for every ten people who call about a unit, six reach voicemail, a full mailbox, or nobody at all.
The second number matters more. A 30-minute delay in responding to a rental inquiry drops renter engagement from 40% to 10%. Not a lost lease necessarily, but a three-quarters reduction in the chance they still care by the time you call back. In practice, a voicemail returned the next morning is usually a dead lead.
Turn that into leases
Assume a 200-unit portfolio generating 30 leasing inquiries in a month. Applying the benchmark:
- 30 inquiries, 60% missed or answered too late, so 18 lost contacts
- Suppose an automated system recovers 12 of those 18, answering in under a minute at any hour
- At a 25% lead-to-lease conversion rate, that is three additional leases a month in leasing season
Three leases. If your average unit rents at $1,500, that is $4,500 a month in rent that was walking out the door, or $54,000 annualised if the pattern held all year. It will not hold all year, because leasing is seasonal, which is why we quote a range rather than a single number.
Then add the vacancy math
Median list-to-lease time hit 41 days in early 2026, against 26 days in 2022. It has since improved to roughly 32 days as of August 2026, but units are still sitting empty substantially longer than they were four years ago, and every day is rent you do not collect.
An assistant that responds instantly and books tours without waiting for someone to get to the inbox typically pulls a few days out of that cycle. Cutting five days off a turn is worth $225 to $375 per turn. On a 200-unit portfolio with a 40% annual turnover rate, that is 80 turns, or $18,000 to $30,000 a year in avoided vacancy alone.
Do not forget the hours
Buildium reports up to 12 hours a week saved on communication and admin for a 20-unit portfolio using AI tooling. Scaling that conservatively to 200 units, call it 20 or more hours a week. That is half a full-time position spent on voicemail triage, inbox sorting, and re-typing maintenance requests into the system, every single week.
The rough total for 200 units: $30,000 to $90,000 a year in recovered rent and avoided vacancy, plus roughly 800 staff hours returned. Against a managed service at $12,000 a year, the arithmetic is not close.
Where this estimate could be wrong
Three assumptions do most of the work, and any of them could be off for your portfolio:
- Your missed-call rate. If you already answer 90% of calls because you have a great front-desk person, the recovery number collapses. Measure yours before believing any of this. Most phone systems will report it.
- Your conversion rate. 25% lead-to-lease is a reasonable middle. If your units are in high demand and you convert at 40%, the number goes up. If you are in a soft market at 15%, it goes down.
- Seasonality. Three extra leases a month is a May number, not a January number.
How to check it yourself in one week
Pull your phone system's call report for the last 30 days and find three numbers: total inbound calls, calls answered, and average time to first response on your leasing inbox. Multiply the gap by your own conversion rate and your own average rent. If the result is not several times what a fix would cost, do not buy one.
The calculator on our property management page does this arithmetic with your numbers instead of the benchmarks.
