How to research an apartment before you sign
A lease is a year-long, ~$18,000 commitment. Here's the due diligence that takes minutes and saves you from the wrong building — the homework listings and a quick AI summary won't do for you.
- 1
Read the reviews over time, not the average
A 4.0★ average can hide a building that was 4.6★ and fell to 3.1★ after a management change. Look at the trajectory and the month it moved — that's what predicts your year, not the lifetime number.
- 2
Be suspicious of a sudden burst of 5-stars
If a place has years of complaints and then a wall of perfect reviews in one recent month, that's often review-gating, not a turnaround. Real fixes don't erase a decade of complaints in two quarters.
- 3
Check whether management actually responds
The share of reviews — especially negative ones — that management replies to is one of the strongest signals you'll find. Silence on 1-star reviews is a red flag.
- 4
Separate the building from the neighborhood
Citywide crime stats aren't the building. Read what residents say about safety at the property (car break-ins, package theft) and pair it with the city's per-capita crime trend.
- 5
Look at deposit-return and fee complaints
Search the reviews for 'deposit', 'fees', and 'move-out'. Surprise junk fees and kept deposits are the most common — and most preventable — renter regrets.
- 6
Verify the practical stuff
Walkability, recent air quality, and the internet you can actually get at the address all matter day-to-day and none of it is on the listing.
- 7
Compare your shortlist side by side
Don't evaluate one place in isolation. Put 3–8 nearby options in one view, ranked by where each is heading.
Common questions
- What's the most important thing to check before renting?
- Whether the building's rating is rising or falling — the trajectory and change-point — not its all-time average. A falling 4.0★ can matter more than a steady 3.6★.
- How can I tell if an apartment is trending down?
- Look for a change-point: a month where the rating dropped and stayed down. Apartment History marks it for you.
- Are apartment reviews reliable?
- Individually, no — they can be gamed. But the pattern over time, the share that management responds to, and corroboration across sources are much harder to fake.
