Key Takeaways
- Always get an ALTA survey—boundary disputes and easement encroachments do not appear in standard title searches.
- Review every lease provision, not just rent and term—right of first refusal and exclusive use clauses can destroy value.
- Unpermitted work creates liability that transfers with the property—check permit history with the building department.
- Rent control status, rental registration, and open code violations are regulatory issues that transfer to the new owner.
Legal pitfalls in due diligence can create liabilities that persist for years after closing. Undiscovered title defects, unresolved zoning violations, problematic lease provisions, and pending regulatory actions can transform a profitable acquisition into a legal quagmire. This lesson examines the legal and regulatory pitfalls that experienced investors still encounter and the controls that prevent them.
Title and Ownership Pitfalls
Title pitfalls extend beyond standard lien searches. Boundary disputes: the property you think you are buying may not match what you actually own—always get an ALTA survey and compare it to the legal description. Easement encroachments: an easement you did not notice in the title commitment may prevent planned improvements. Unrecorded interests: verbal agreements, prescriptive easements, and adverse possession claims do not appear in title searches. Forged deeds: while rare, title fraud through forged deeds creates ownership disputes that take years to resolve. Heirs and estate issues: if the seller acquired the property through inheritance, ensure probate was properly completed and all heirs have conveyed their interests. Purchase owner's title insurance (not just lender's) to protect against defects that survive closing.
Lease and Tenant Pitfalls
Lease pitfalls that are commonly missed: below-market rent locks—a tenant with a 10-year lease at below-market rent that you cannot increase until expiration. Right of first refusal—a tenant with the right to purchase the property, which must be offered before you can sell. Exclusive use clauses—a commercial tenant whose lease prohibits competing uses that affect your ability to lease other spaces. Relocation clauses—tenant rights to relocate within the building, disrupting your renovation plans. Personal guarantees—commercial leases without personal guarantees mean you have no recourse beyond the tenant entity. Tenant improvement obligations—landlord commitments to fund future build-outs that may not appear on the balance sheet. Review every lease provision, not just rent and term.
Regulatory and Compliance Pitfalls
Regulatory pitfalls include: unpermitted work—renovations performed without proper permits create liability and may need to be torn out or retroactively permitted at significant cost. Certificate of Occupancy (C of O) violations—if the current use does not match the C of O, you may be required to restore the original use. Rent control and stabilization—in jurisdictions with rent regulation, inheriting regulated units limits rent increases and may restrict tenant termination. Local registration requirements—many cities require rental property registration, and failure to register can result in fines and inability to collect rent. Code violations—outstanding violations transfer with the property; check with the local building department for open violation cases. ADA compliance—commercial properties may face ADA lawsuits for accessibility deficiencies that transfer with ownership.
Common Pitfalls
Purchasing lender's title insurance but not owner's title insurance
Risk: Lender's policy protects only the lender—the buyer has no coverage for title defects discovered after closing
Always purchase an owner's title insurance policy ($1,000-$3,000) for lifetime protection against covered defects
Not checking for unpermitted renovations in the building department records
Risk: Unpermitted work may need to be demolished, retroactively permitted at great expense, or creates insurance gaps
Pull the complete permit history and compare to the property's actual condition; verify C of O matches current use
Overlooking rent control or stabilization status in regulated jurisdictions
Risk: Inheriting rent-regulated units dramatically limits upside and restricts tenant management
Verify rent regulation status for every unit in regulated jurisdictions; model restricted rents into the pro forma
