/// COMMON QUESTIONS · 6357 COSTELLO AVE

The short answers.

Is 6357 Costello Ave rent controlled?

Outside LA RSO coverage on these records — most California multifamily over 15 years old falls under the AB 1482 statewide cap of 5% plus CPI, never more than 10% per year. This is an inference from public assessor records, not a determination — confirm the certificate of occupancy date with the LA Housing Department or ZIMAS before you rely on it for pricing or notices.

How many units does 6357 Costello Ave have?

County records list 4 units at 6357 Costello Ave, classified as fourplex across 9,268 square feet of building area, averaging about 2,317 square feet per unit. Unit counts on the roll can lag permitted conversions and unpermitted additions in both directions.

When was 6357 Costello Ave built?

The assessor roll gives a build year of 2008, which is after the October 1978 RSO cutoff. Age drives more than character here: it sets rent-cap exposure, seismic retrofit obligations, and what a lender will underwrite.

When did 6357 Costello Ave last change hands?

The most recent transfer on the roll was recorded February 2014. Not every recorded transfer is a market sale — refinances, trust transfers, and family conveyances all appear in the same field, and those do not reset the assessed value.

What is 6357 Costello Ave assessed at, and is that what it is worth?

The current assessed value is $1,563,026 ($625,210 land, $937,816 improvements). Assessed value is not market value. Under Proposition 13 it resets only on a change of ownership and then climbs about 2% a year, so a long-held building is often assessed far below what it would trade for — and this one has held its base year for roughly 15 years.

Would the owner of 6357 Costello Ave face a big tax bill on a sale?

Possibly. A base year going back roughly 15 years usually means a low tax basis, and a low basis means a large taxable gain on a straight sale — capital gains plus depreciation recapture, with California taxing gains at ordinary income rates. It is also why long-held buildings so often sell through a 1031 exchange instead, or pass through an estate for the step-up in basis.

How do I find out what 6357 Costello Ave would sell for today?

Public records give you the frame — units, size, age, assessed value, when it last traded — but pricing needs in-place rents, expenses, and the condition of the units, none of which appear in county data. A broker valuation puts closed comps and a rent survey against the actual rent roll. Shaya Lowenstein does that free for LA multifamily owners, typically within 48 hours, with no obligation to list.
