The agency's report on how efficiently it collects payments is not reliable, so the reported collection rates may be inaccurate.

The agency spent over P83 million on infrastructure and equipment for the BP2 program but incorrectly recorded these as expenses instead of assets, which misstates the financial statements.

The agency failed to properly record and report transactions related to the SSS Dormitory and Apartment Loan Program. This includes not recognizing receivables and payables, misclassifying properties, not reconciling accounts, and not setting aside allowances for potential losses, leading to inaccurate financial statements.

The agency's records for employee leave credits and terminal benefits are incorrect because the HR department did not provide accurate data. This has caused the financial statements to overstate liabilities and accumulated surplus by about P2.15 million.

The financial statements contain errors in the accounts of NGC (now PhilGuarantee) totaling over half a billion pesos, which have been misstated for many years. The agency has not taken action to correct these errors or obtain the necessary documentation to write them off.

The agency collected money from housing beneficiaries but did not have a plan to use that money to build more houses as required by its mandate.

The agency planned to buy a financial system for P25 million but did not follow through, which affects the reliability of financial data and the ability to provide proper audit trails.

The NHA spent billions more than budgeted for military and police housing projects, violating budget laws, and also mischarged expenses, worsening the deficit.

The NHA failed to record over P10 million in transactions over five years, making its cash balance inaccurate and unreliable.

The NHA recorded loan receivables without proper loan agreements for community-based housing projects, violating accounting standards.

The NHA paid over P213 million in incentives without required approvals from the Department of Budget and Management and the President, and used incorrect savings calculations, violating rules.

The NHA sold a property without following proper procedures, potentially getting a lower price, and has been unable to collect over P17 million due to missing survey plans and poor planning.
