I Found a 3-Unit Property in Long Beach Listed $105K Over Market Value and Here's Why

I was pulling comps for a buyer last week when I came across a North Long Beach listing that stopped me mid-scroll. Three income-producing units — a single-family residence, a full ADU, and a JADU (Junior Accessory Dwelling Unit) — priced at $1.05M. On paper, it looked like a deal. When I dug into the numbers, it was overpriced by at least $105K, and probably closer to $175K.

Here's exactly how that happened, and what it means if you're buying or selling a property like this in Long Beach.

The Comparable Properties Problem

The listing agent priced this property using duplex comps. That's the mistake. Two-unit duplexes in that part of North Long Beach were selling around $1.1M at the time, so a three-unit property at $1.05M looked like a bargain by comparison. The problem is that ADU properties and duplexes are not the same thing in the eyes of appraisers, lenders, or buyers — and the market data reflects that clearly.

When I pulled SFR + ADU comps specifically — not duplexes, not multi-unit buildings, but actual single-family homes with accessory dwelling units — the comparable sales ranged from $825K to $875K. That's a $175K to $225K gap from where the property was listed. This is the same comp discipline I walk through in Before You Build an ADU in Orange County, Check the Comps First — running the wrong comp set can cost you six figures before you've even started negotiating.

Why JADUs Don't Close That Gap the Way You'd Think

The seller likely reasoned that the JADU justified the higher price. And yes, JADUs add value — but not dollar-for-dollar relative to construction cost. In the Long Beach and Orange County market, JADU builds typically run around $90K. But Fannie Mae's appraisal guidelines for secondary dwelling units are explicit: accessory units are valued based on their contribution to the overall property, not as standalone income units. So a $90K JADU doesn't add $90K in appraised value.

A realistic valuation here looked something like this: SFR + ADU baseline at $850K, JADU contribution at $60–65K, bringing the property to roughly $915K. Not $1.05M.

The Market Signal That Confirmed It

When I called the listing agent to ask about the property, the first thing they said was that the price was "flexible." That phrase is a red flag in any market. Flexible pricing on a property that's been sitting means the seller has already seen enough showings without offers to know something is wrong. It also tells you the listing agent knows the price isn't right but hasn't been able to reset expectations with the seller yet. The Long Beach ADU market data through March 2026 shows this clearly — correctly priced permitted properties are moving in 25–40 days, while overpriced listings in transitional neighborhoods are sitting 75+ days before price corrections.

How to Negotiate When the Comps Don't Match the Asking Price

If you're a buyer and you find yourself looking at a property like this — appealing on paper, overpriced in practice — here's how to approach it.

Start by building your own comp set. Pull only SFR + ADU sales, not duplexes or triplexes. If the listing agent used multi-unit comps, your agent should be able to show that directly in the counter.

Second, get a lender involved early. If the property is overpriced relative to ADU comps, there's a real chance it won't appraise at the purchase price even if you agree to it. An experienced lender who understands ADU appraisals will flag this risk before you're in contract.

Third, understand that ADU income isn't counted the same way duplex income is in most conventional loan programs. Under Fannie Mae's ADU income eligibility guidelines, lenders can count rental income from one ADU unit toward qualification — but the rules are different from a true two-unit property, and that affects how many buyers can qualify. That shrinks the buyer pool, which is leverage for you.

Finally, if the seller won't move to a price the appraisal can support, walk. Overpriced ADU listings correct downward. This one will too.

What This Means If You're the Seller

If you own a property with an ADU or JADU and you're thinking about selling, price it against the right comps from day one. Starting too high and chasing the market down costs you time, negotiating power, and ultimately more money than if you'd priced correctly on day one. I've seen sellers lose $40–50K in net proceeds by sitting on an overpriced listing for 90+ days versus pricing right and selling in three weeks.

The Long Beach ADU market has enough qualified buyers in the $850K–$1M range that a correctly priced, permitted property moves. It's the mispriced ones that sit.
