Introduction: Since the wake of the 21st century, rising cases of collapsing investment buildings, renters rejection of properties structurally unfit as business or residential accommodations, and ongoing sealing of suspected weak buildings especially in Nigeria has become a source of serious concern. It is no longer news that the financial/other benefits from many housing investments and owner-occupied homes might be on-the-line sequel to risks of degenerating building conditions in-spite of assurances by the building contractors that their properties would last a hundred years. It has become imperative to make evaluation reports regarding the usage-to-carrying capacity status of these buildings in maintenance and valuations as sustainability measures in directing investors decisions and government actions regarding usage compliances among housing occupiers and owners of real estate facilities. A sincere transformation in the way housing is managed is the key direction.

Goal: This paper makes strong case for mandatory technical checks in real estate facilities before and during letting as measures to checking this ugly trend of building collapses affecting investments and owner-occupied properties. It therefore recommends the designing of housing quality test assurance policy applicable on all in-use and to-use facilities to eliminate/reduce significantly usage impacts on the lifespan of real estate facilities, its effects of investors decisions and public trusts on the Estate Surveyors and Valuers competence to guarantee sustainable durability and financial growth especially for investment-driven real estate developments.

Methodology: Nigeria is taken as study area. Author sort the contributions of 30 Practicing Estate Surveyors managing properties in 20 out of 36 states of the federation by conducting structured exploratory interviews to verify the inclusivity of quality tests in real estate investment practices in Nigeria. The questionnaire was evaluated using the SWOT Analysis technique to substantiate the lack and need for such tests by practitioners. Also, the illusionary experimentation was employed to demonstrate the gap in reporting housing durability alterations and its impact on durational and financial decision projections in real estate facilities. Study outcomes were assessed using descriptive analysis techniques and presented on suitable tables.

Findings: Qualitative Usage Assurance Tests in real estate facilities has not been in in-depth considerations; many houses are let without conducting stability impact tests, lack operational evaluation and most often has irregularly-graduated depreciation effects on their durability. Findings also shows possible future risks of more collapses in high density urban buildings capable of undermining the advisory competence of Estate Surveyors and Valuers in handling Investments in Real Estate Facilities.

Conclusion: Usage Quality Assurance Test should be stepped up as mandatory service in business or multi-level properties, certified by an Estate Surveyor and Valuer to guard the nation against unprecedented records of abrupt investment losses. This is wake-up call to the profession to reconsider the use-to-value implications of facility spaces before, during and after letting to properly guide the investment decisions and project plans of investors in real facilities.

Originality: This study is the first-ever attempt to introduce and advance the application of technical reporting practices on real estate facilities. It is an eye-opener to possible gaps and solutions to checking causes of distrust in professional reports regarding structural durability and usage reductive effects on investment values of real estate facilities.
