Complete Checklist (8 Items)

STEP 01

Verify Rent-Stabilized Units

Determine how many units are rent-stabilized by checking DHCR records, property tax bills for 421-a/J-51 benefits, and building age/size. Rent-stabilized units significantly affect property valuation and cash flow projections.

STEP 02

Review HPD Registration

Check that the building is properly registered with HPD. Review the registration for owner name, managing agent, and number of units. Unregistered buildings cannot collect rent increases.

STEP 03

Audit Open Violations

Search DOB, HPD, and ECB for all open violations. Calculate the estimated cost to resolve all violations. A high violation count indicates deferred maintenance and potential capital expenditure needs.

STEP 04

Review Rent Roll Against Market

Compare actual rents to market rates and legal regulated rents. Identify units with preferential rents. Assess rent upside potential while considering rent stabilization limits.

STEP 05

Check Building Complaint History

Review HPD and DOB complaint histories. Frequent complaints indicate tenant dissatisfaction and potential management issues. Pattern of heat complaints may signal boiler problems.

STEP 06

Verify Tax Benefit Status

Check for 421-a, J-51, or other tax benefits. Determine expiration dates. Expiring benefits will increase operating costs. Some benefits require rent stabilization compliance.

STEP 07

Review Operating Expenses

Analyze real estate taxes, water/sewer, insurance, fuel, maintenance, and management costs. Compare to industry benchmarks. Identify any extraordinary expenses or deferred maintenance.

STEP 08

Check for Litigation

Search court records for active litigation involving the building or owner. Check for tenant lawsuits, HP actions, Article 78 proceedings, and harassment complaints. Pending litigation represents risk.

Rental property investment in NYC requires understanding a complex regulatory environment including rent stabilization, HPD enforcement, and tenant rights. This checklist helps investors and managers identify risks and opportunities.
