Liquidity (LQ) and asset quality (AQ) management present significant challenges to mortgage bankers in their efforts to improve profitability (PR). When liquidity increases, there is no positive impact on mortgage asset growth; however, this trend indicates that asset management and liquidity positions are not well managed. To run a viable mortgage business, mortgage bankers need to have a good grasp of the association between LQ, AQ, and PR. Anchored in the profit theory paradigm, the purpose of this multiple regression study was to examine the relationship between LQ, AQ, and PR of mortgage banks (MBs) in Nigeria. Archival financial data of 16 randomly sampled MBs covering a period of 8 years from 2009 to 2016 were used. Data were analyzed using multiple panel regression incorporating two PR models, net interest margin (NIM) and return on asset (ROA). The regression result indicated that LQ and AQ constructs significantly predicted PR as measured by NIM because F (8, 80) = 2.061, p = 0.014, p < 0.05, and effect size given by R2 = 0.458, signifying 46% variation in NIM. The model of PR as measured by ROA also indicated that LQ and AQ constructs were significant because F (8, 80) = 4.043, p = 0.000, p < 0.05, with effect size measured by R2 = 0.624, indicating 62% variation in ROA. The findings emphasized the need for optimization of LQ and AQ to maximize PR. The implications for positive social change include the potential to provide the business leaders in the mortgage industry with knowledge about optimization of LQ and AQ as drivers of PR. In addition, when business owners achieve increase profitability, they may provide more employment opportunities, better working conditions, better compensation plans, and more access to mortgage finance options.
