Buying a rental property involves acquiring not just the physical building but also the landlord-tenant relationships that come with it. Existing tenants remain in place. Existing leases continue. And existing compliance obligations transfer to you — including obligations you may not have known existed.
Understanding what actually changes at closing is essential for avoiding early mistakes that create liability from your first day of ownership.
What transfers to you
Existing tenancies. All existing tenancies continue under their current terms. You cannot immediately terminate month-to-month tenants just because ownership changed. Any protections or restrictions that applied to those tenancies still apply — under both the ownership of the seller and now under yours.
Existing leases. Written leases continue in force through their expiration. You inherit any specific terms — pet policies, rent amounts, renewal options, tenant improvement obligations — that the previous owner negotiated. Even if you disagree with those terms, they bind you.
Existing security deposits. The seller should transfer all security deposits to you at closing (or credit you at closing for their value). You now hold those deposits for the tenants and are subject to whatever deposit rules your jurisdiction imposes. If the previous owner didn't handle deposits correctly, that liability may transfer to you.
Existing compliance status. If the previous owner registered the property annually, served required disclosures, or maintained proper records, you inherit those obligations from the point of purchase forward. If they didn't, you may inherit gaps that need remediation.
What changes for you specifically
Registration obligations
Many jurisdictions require new owners to register or update registration within a specific window:
Los Angeles. New owners of RSO-covered properties must register with LAHD within 45 days of acquisition. Failing to do so bars you from collecting rent until registration is complete — including for existing tenancies with legal rent obligations.
New York City. HPD registration must be updated within 5 days of any ownership change. This applies to all buildings requiring HPD registration (3+ units or non-owner-occupied).
San Francisco. SF Rent Board registration typically transfers with the property tax bill, but new owners should verify Rent Board records reflect the change of ownership.
Missing these windows can create fines, bar to eviction proceedings, and administrative headaches from day one.
Notice to existing tenants
Some jurisdictions require notice to existing tenants of the change in ownership:
Los Angeles. New RSO owners must serve a notice to existing tenants within a specific window identifying the new landlord, contact address for service of legal process, and other statutorily required information.
San Francisco. Similar notice obligations apply.
All jurisdictions. Under Civil Code §1962 in California, a landlord must provide certain contact information to tenants — including phone number, address for legal service, and person authorized to accept notices. This is required at the outset of every tenancy but also on ownership change.
Failing to provide required notices can affect the enforceability of future notices you serve.
Tenant information and records
At closing (or as soon as possible after), you need:
- Copies of all current leases
- Move-in inspection records
- Payment history for the last 12+ months
- Deposit records with amounts and dates received
- Copies of any prior served notices (rent increases, corrections, warnings)
- Any registration confirmations or agency filings
- Any pending complaints, notices, or violations
- Contact information for each tenant
- Any communications about the property from tenants, agencies, or attorneys
If the seller can't provide these, you're purchasing a compliance risk without visibility into what you're buying.
What the seller should have disclosed but may not have
Standard real estate disclosures often miss landlord-tenant specifics:
Unregistered RSO/RS units. In LA, SF, or NYC, buildings may have Rent Stabilization or RSO coverage that was never registered by the previous owner. You inherit both the coverage obligation AND the potential penalty for non-registration.
Preferential rent below market. Rent-stabilized units may have current rents well below allowable maximums due to landlord preference. This isn't a defect but it affects your income projections.
Improperly deregulated units. Units the previous owner claimed as deregulated may have been improperly deregulated. Reversal of the deregulation exposes you to overcharge liability going back years.
Owner-move-in evictions in the last 5 years. If the previous owner evicted a tenant claiming owner move-in but never actually moved in, this creates constraints on future evictions and re-rental terms.
Ellis Act withdrawals. If units were withdrawn from the market under Ellis Act by the previous owner, restrictions on re-rental follow the property, not the owner. You may inherit relet obligations you didn't know about.
Habitability violations. Open HPD, LAHD, or DBI violations continue. You become responsible for correcting them.
What you should do immediately after closing
Week 1:
- Register with all applicable agencies (LAHD, HPD, SF Rent Board, etc.)
- Serve required notices to existing tenants (change of ownership, contact information)
- Confirm receipt of security deposits from seller
- Obtain any known violation history
Week 2-4:
- Review each existing lease for terms that constrain your operations
- Identify any tenants who may qualify for special protections (protected tenant status, Section 8, etc.)
- Assess registration status for prior years — was the property registered under previous ownership?
- Verify covered/exempt status of each unit under applicable rent control
First quarter:
- Establish direct payment and communication channels with each tenant
- Complete any inherited habitability issues
- Review the property's compliance history and remediate gaps
- Consider forming professional relationships with local attorneys and property managers
What NOT to do immediately
Don't immediately raise rent. State notice periods and rent-control caps apply the same to you as to the previous owner. Rent increases must follow the same rules.
Don't attempt to terminate existing tenants without cause. Existing tenants remain in place. Termination requires the same just cause (where applicable) as it did under the previous owner.
Don't ignore existing leases. You cannot unilaterally modify terms of an existing lease.
Don't assume prior compliance. Even if the seller says everything is registered and current, verify with the actual agencies. Sellers sometimes misstate compliance status.
Don't do owner move-in evictions immediately. Some jurisdictions restrict owner move-in for new owners for a period after purchase. Even where permitted, doing so in the first year of ownership invites scrutiny.
The compliance surface expands with ownership
Your obligations as a new owner are broader than the previous owner's obligations were before you bought:
- You must satisfy any inherited compliance gaps within statutory correction windows
- You must maintain records going forward that would satisfy an audit or dispute
- You must serve required disclosures to tenants at times that may differ from ongoing tenancies (e.g., annual notices required in specific windows)
The practical bottom line
Buying a rental property is a compliance event, not just a real estate transaction. Existing tenancies, existing leases, and existing obligations transfer to you at closing. What changes for you specifically is the requirement to notify agencies, tenants, and various parties of the change — often within tight windows.
Do your due diligence before closing on tenant status, registration history, and any pending violations. Have a plan for the first 30 days that addresses immediate registration and notice obligations. Consult a landlord-tenant attorney if you're buying an RSO/RS/Rent Stabilized property — the specific rules there are more restrictive than for market-rate rentals.
