85% of San Francisco landlords fear application fraud as AI made faking paystubs easy

Most stories about rental fraud focus on renters who send deposits for apartments that were never real in the first place. This is the reverse. In San Francisco, AI tools are helping applicants fake paystubs to win apartments they don't qualify for.

A survey of 1,400 landlords nationwide by the background-check company Checkr found 85% of San Francisco landlords worried about fraud in applications. Of the 14 cities surveyed, San Francisco had the highest share concerned about fake or altered pay stubs, bank statements, and income documents.

Why the incentive is highest in San Francisco

The fraud is happening because San Francisco's typical monthly rent is $4,539, up 28.6% over the past year and the steepest increase in the entire country, with a one-bedroom on the open market now topping $4,000. When a unit draws a dozen applicants and the tiebreaker is who looks the best on paper, faking the paystubs becomes worth doing.

The cities where a faked income document buys the most are the ones where the rent-to-qualify bar is highest and competition is fiercest, and San Francisco leads both. A tenant who can't prove the income the market demands has a large financial reason to manufacture it, and AI dropped the cost of faking it.

Milan Jezdimirovic, a leasing agent at Compass, has dealt with document tampering for years. He caught edited files with an income-verification app back in 2024 and made the applicants provide real proof. The new versions are harder to catch. "AI did not create this, but it made fake documents faster to produce and harder to spot quickly," he said. "We now have to verify everything more carefully: employer, deposits, prior landlord, credit check, and ID."

What happens when it works

The survey found that landlords usually catch this too late. In San Francisco, 70% of surveyed landlords said they'd found or suspected application fraud that led to an eviction, and 28% said a fraudulent tenant cost them at least $5,000 in missed rent, damage, and other expenses.

One in three said they'd discovered identity theft in their buildings, and another 17% suspected it but couldn't prove it before the tenant left. Victor Kabdebon, who runs Checkr's tenant screening platform, said even experienced landlords may not realize they've been fooled until it's too late.

San Francisco's tenant protections, which are among the strongest in the country, sharpen the problem for owners. Once a tenant is in, removing them is slow and expensive, and landlords in the survey were more worried than the national average about breaking eviction law while trying to get a fraudulent tenant out. A faked pay stub that gets someone as a tenant can take months and thousands of dollars to undo.

What it means for honest renters

Jezdimirovic's list of checks, employer, deposits, prior landlord, credit, and ID, is now the baseline in a competitive SF search, and it means a slower, more invasive process for people with legitimate documents.

If you're applying in a tight market, the move is to make verification easy rather than resisting it. Offer to connect income directly through a verification service rather than uploading a PDF, since a bank-linked confirmation is exactly what a faked document can't replicate. Give the prior landlord's real contact rather than a friend's number. The applicant who is obviously verifiable stands out precisely because so many aren't. Our guide to what you need to apply for an apartment covers the documentation.
