The 2007-2009 recession negatively impacted the global economy, especially the real estate industry and multifamily rental properties. Obtaining credit became difficult, real estate lost 41% equity, 223 commercial banks failed, and 3.2 million homes were in foreclosure. Grounded in systems theory, the purpose of this causal comparative study was to examine the impact of mortgage lender type on the average ranking of 8 mortgage underwriting outcome measures. For the study, 44 accredited mortgage professionals completed an online-survey. The results of the analyses of variance indicated a statistically significant (p < 0.001) lender type effect on credit score and loan-to-value ratio. Further analyses on credit score indicated a significant (p = 0.006) relationship between Category A and B lenders, Category A and C lenders (p < 0.001), and Category B and C lenders (p < 0.001). Further analyses on loan-to-value ratio indicated a significant (p = 0.017) relationship between Category A and B lenders and also Category A and C lenders with (p < 0.001), but the difference between Category B and C lenders is not statistically significant with (p = 0.063). The implications for positive social change include economic growth and expansion, as access to financing increases. Tenants in multifamily rental properties might also benefit from economic growth as the standard of living could increase when landlords initiate capital spending and development.
