You've got two applications in the inbox, the unit has been empty for a week, and one applicant has a credit score that looks great. The reference call feels like a formality at that point. It isn't. It's one piece of a bigger tenant screening process, and it's the piece owners skip first when they feel rushed.
This post is for rental owners and small investors who want to know what to listen for. We'll cover what a reference check should confirm, which questions get real answers, which red flags matter, and which questions you should never ask. A few of those limits are legal ones.

Why Reference Checks Carry Extra Weight on the Peninsula
San Mateo County is one of the most expensive rental markets in California. Good rentals in Redwood City pull in multiple applications fast, and that speed is the problem. Owners feel pressure to approve quickly, and applicants know it.
Two local patterns make references trickier here:
- Short local histories: Plenty of applicants work in tech or biotech along the Peninsula corridor. Their income is often strong, but they may have only a year or so of renting nearby.
- Rushed paperwork: With vacancy low, applicants sometimes hand over incomplete reference info and hope nobody pushes back.
State tenant protections also make it hard to fix a bad placement after move-in. Before you set terms, check the rent increase limits that apply to your unit and Redwood City's local tenant protection rules, since the rules can differ from city to city. Getting the tenant right the first time beats any legal fix later.
A standard process fixes most of this. Same questions, same order, every applicant.
What a Reference Check Should Confirm
Think of a reference as a fact-check on the application. You're confirming what the applicant already told you and looking for what they left out. Around three years of rental history is a typical ask, and it's a fair target.
On every prior-landlord call, confirm these:
- Dates and address: Do move-in and move-out dates match the application?
- Rent amount: Does it match what the applicant says they paid?
- Payment history: Late payments, bounced checks, payment plans.
- Lease compliance: Written warnings, noise complaints, unapproved pets or occupants.
- Property condition: Did the unit come back in reasonable shape, and what came out of the deposit?
- Move-out: Did they give proper notice and leave on schedule?
Short list. Every line has a factual answer, and that's the point.
Questions That Get Real Answers
Open-ended beats yes or no
Picture a landlord who asks a former landlord one question, "Would you rent to them again?", and hears "yes." Sounds great. But the former landlord may have said yes because they wanted that tenant gone and a bad word might slow the move-out.
Ask questions that need a detail to answer:
- "What was the monthly rent, and did it arrive on time?"
- "How many times did you send a late notice or lease warning?"
- "How did the unit look at move-out compared with move-in?"
- "Did they give proper notice before leaving?"
- "Did any issues come up with neighbors?"
- "Is there anything you'd want to know if you were in my seat?"
That last one gets surprising answers. People who won't volunteer a problem will often confirm one when you give them room.
Call the landlord before the current one
A current landlord may be eager to see the tenant leave. If you can reach the landlord before that one, you get a view with no motive attached. If the applicant came from month to month rentals in Redwood City or elsewhere, there may be no formal lease to check, so lean harder on payment records and the earlier landlord.
Weigh Each Source by How Easily You Can Verify It
A glowing verbal reference can be the least reliable signal in the stack. Experienced managers tend to trust documents over opinions.
| Source | What it can confirm | Where it falls short |
|---|---|---|
| Current landlord | Rent, address, current status | May want the tenant gone |
| Previous landlord | Full tenancy, move-out, deposit | Harder to reach, memory fades |
| Payment records | Dates and amounts paid | Applicant may not have them |
| Employer or HR | Title, start date, employment status | Often limited to those facts |
| Screening reports | Collections, judgments, evictions | Don't show behavior inside the unit |
Ask for a lease copy, a rent ledger, or proof of on-time payments when you can. A reference who talks nicely but can't back anything up is worth less than a boring bank record.
Checking Employer References and Short Histories
For applicants new to the area, the employer call matters as much as the landlord call. You want to confirm:
- Job title and start date
- Full-time or contract status
- Whether pay matches the income on the application
Get the employer's number from the company's main line or website, not from the application. Pair it with pay stubs or an offer letter. Our screening covers income and employment alongside credit, background, rental history and eviction records, so no single reference carries the whole decision.
A thin rental history doesn't kill an application. When someone doesn't meet standard income, credit or rental history qualifications, a cosigner may be an option. They have to meet the financial requirements and sign a guarantor agreement.
Red Flags, and How to Spot a Fake Reference
Say an owner calls the number on an application and reaches someone who turns out to be the applicant's friend posing as a landlord. It happens. A structured process makes it much harder to pull off.
Look up the owner of record for the address the applicant lists. County property records usually show who owns a property. If the name on the phone doesn't match, keep digging.
Watch for these red flags:
- Too smooth: Instant praise with no dates, amounts or details.
- Cell number only: No business name, no property address.
- Name mismatch: The "landlord" isn't the owner of record or the listed manager.
- Vague on basics: Can't recall the rent or the move-out date.
- Unexplained gaps: Months with no address and no explanation.
- Pressure to skip: The applicant says other owners are waiting and you should just approve.
That last one is the tell. Applicants with nothing to hide rarely mind a phone call.
Stay Inside Fair Housing Lines
Reference calls are where owners wander into trouble. A friendly chat turns into questions about someone's family or background, and that creates liability.
Don't probe these topics with references or applicants:
- Family status or whether they have kids
- National origin or immigration status
- Disability
- Source of income, including housing vouchers
- Religion, race, sex or any other protected trait
State and federal fair housing law restricts how you use these topics, and the details change, so check current rules or ask an attorney. A simple rule works. Ask about behavior you can document, like rent paid, notices received and condition at move-out.
If a screening report plays any part in a denial, federal law requires an adverse-action notice, covered in the FAQ below. If information from a past landlord or employer drives the denial, federal law may require you to tell the applicant, at the time of the denial, that they can ask in writing within 60 days for the nature of that information. Check with your attorney or manager about what you owe the applicant.
Write Everything Down
When asked what mistake owners make most often, our answer is not recording documents. We spend a lot of time hunting for leases, applications and rent increase notices when we take over a property. As we put it, documentation "is really all that you have outside of he said, she said."
Here's one example. We took over a Fremont single-family home where the prior manager had never inspected the property, and rent had arrived sporadically and in the wrong amounts. The tenant also had a hoarding problem. We inspected, posted proper notices and finished the eviction within 90 days. After renovations, we re-leased the home, and the new family renting it has paid on time for about two years.
You can't enforce what you can't prove. For every reference call, log this:
- Date and time of the call
- Name, title and phone number of the person you spoke with
- Their answers, in their words
- How you confirmed they were who they claimed to be
- Which applicant the notes belong to
How We Handle It, and When to Hand It Off
We manage 112 properties and have been at it for 7 years. A good approach is standard questions, verifiable documents and a written record, run the same way for every applicant. Properties lease first-come, first-served once a completed application and all required fees are in.
We also stand behind the result. If a tenant we place breaks their lease within the first 9 months, we re-lease the property at no additional cost to you. That's our Lease Assurance in practice.
Clear communication matters on the applicant side too. One renter said of their experience, "The instructions were clear and the communications consistent." A clear process makes good applicants easier to read.

FAQ
How many references should I check on a rental application?
At minimum, check the current landlord, the previous landlord and the employer. Around three years of rental history is a typical target.
Can I skip reference calls if the credit score is strong?
No. A credit report shows how someone handles debt, not how they treated a rental unit or followed a lease. Landlord and employer references fill that gap.
What if an applicant has no rental history?
It depends on the rest of the file. A cosigner who meets the financial requirements and signs a guarantor agreement can bridge the gap, along with solid income and employment verification.
Do I have to tell an applicant why I turned them down?
If a screening report played any part in turning down an applicant or worsening their terms, federal law requires an adverse-action notice. It must say you took adverse action, give the screening company's name, address and phone number (including a toll-free number if it is a nationwide company), and state that the company did not make the decision and can't explain the reasons. It also has to tell the applicant they can get a free copy of the report if they ask within 60 days and can dispute it with the company, plus the credit score and key factors if one was used.
What if a reference never calls back?
Follow up in writing and log every attempt. Don't fill the gap with a guess, and don't let a competing application rush you into approving without verification.
