The riskiest period in owning a Los Angeles apartment building is the first three months, and the risk is almost entirely self-inflicted. New owners arrive with a business plan, start executing it immediately, and generate in eight weeks the tenant complaints, compliance gaps and reputational problems that will shape the next several years of operating the asset. The buildings that transition well are the ones where, from the tenants' perspective, almost nothing happened.
Register the ownership change with LAHD. RSO buildings require the new owner on record. This is administrative and it is also the foundation of every lawful rent increase you take later.
Complete the housing authority payee change for any voucher tenancies. Start it during escrow — if it is not processed, the first post-closing assistance payment may not reach you.
Confirm insurance is bound and correct from the closing date, including any difference-in-conditions layer.
Take over the deposit accounting and confirm it reconciles to the credit you received and to the estoppels.
Set up rent collection and tell tenants, in writing, where to pay. Do this before the first of the month, not on it.
One short written notice, sent to every unit. It should say who now owns the building, where and how to pay rent, who to contact for repairs, and — plainly — that their tenancy, rent and protections are unchanged.
That last sentence prevents more problems than anything else you will do. In its absence, tenants fill the vacuum themselves, usually with the assumption that a new owner means a campaign to remove them. Anxious tenants call tenant counsel, and tenant counsel is active in Los Angeles.
Do not use the letter to announce plans, request information, or introduce new rules.
Meet the on-site manager if there is one, and understand the arrangement — employment terms, the unit, and whether any of it is documented. California requires a resident manager at 16 or more units, so if you are replacing them you need a plan, not a gap.
Walk every unit you can, with proper notice and a legitimate purpose. You are building a maintenance picture, not inspecting tenants.
Read the compliance file properly. Registry history, open citations, systematic inspection status, retrofit position. You reviewed this in diligence; now work it as an owner.
Verify the rent roll against actual collections for the first full month. This is where you discover what the estoppels did not say.
Do the repairs. Especially anything habitability-related. A new owner who fixes the long-ignored plumbing complaint in week two buys goodwill that is worth real money later, and removes a habitability exposure that was sitting there waiting.
Do not serve rent increases in month one. Even lawful ones. It confirms every fear the building has about you and it costs you the cooperation you will need.
Do not start a buyout campaign immediately. LA's buyout rules require written disclosure first, a 30-day rescission window, and filing with LAHD within 60 days. A new owner running an aggressive campaign is also the exact fact pattern that produces tenant anti-harassment claims.
Do not reduce services to cut costs. Discontinuing a service that existed under the prior owner can be a reduction in housing services under the ordinance, and it is a claim.
Do not begin renovation without checking what it triggers. On a pre-1978 building, work that disturbs asbestos-containing material or lead paint carries specific licensing, containment and notification requirements.
Do not let the manager set the tone unsupervised. Most tenant problems I have seen after a sale trace to an offhand remark by someone on site — usually "the new owner is going to clear the building." Brief everyone who speaks to tenants, once, on what they may say.
Days 1–30: stabilise. Registrations, insurance, deposits, collections, the tenant letter, urgent repairs. Change nothing visible beyond fixing things.
Days 30–60: understand. Full maintenance assessment, vendor contracts reviewed and re-bid, utility and expense verification against your underwriting, unit-by-unit condition and tenancy profile.
Days 60–90: plan. Now build the actual capital and repositioning plan with real information — what each unit needs, what turnover is realistically going to look like, what the retrofit or capital items cost with bids in hand.
Execution starts after that, on a building you now understand, with tenants who have no particular reason to be alarmed.
Do I have to notify tenants that I bought the building?
You will be telling them where to pay rent regardless, so the practical answer is yes. Doing it clearly and immediately — including that their tenancy and rent are unchanged — is the single cheapest risk reduction available to a new owner.
When can I take my first rent increase?
It depends on when the unit last received one and which regime governs. Each unit has its own twelve-month clock, and the increase must comply with the applicable cap and notice rules, with registration current. Check unit by unit rather than building-wide.
Can I replace the property manager immediately?
Yes, subject to the management agreement's notice terms. Be careful where the manager also occupies a unit — employment and occupancy are separate questions, and in LA City the occupancy one can be complicated.
What if I find something in month two that diligence missed?
Document it and deal with it. Whether the seller has any responsibility depends on the purchase agreement's representations and survival periods — worth a call to your attorney early rather than after those periods expire.
The upside in a Los Angeles apartment building is real, and it arrives through turnover on the building's timetable rather than yours. The first ninety days are not when you capture it. They are when you make sure nothing you do in month two costs you more than the upside is worth — and the way to do that is to fix things, tell people the truth, and change nothing visible until you understand what you bought.
