We study whether tax considerations are an important determinant of commercial mortgage default. We also study whether large lenders are better informed, or better at interpreting information for lending purposes, and hence have lower foreclosure rates; whether lenders have more information on larger borrowers than smaller borrowers, and hence have lower foreclosure rates on larger loans; and whether commercial mortgage defaults are related to debt service coverage and loan-to-values, both initial and contemporaneous. The paper's main findings are fourfold. First, there is evidence that tax considerations influence investors' decisions about when to put assets to lenders. The results are consistent with the argument of Constantinides (1984). Second, the evidence suggests that large lenders are especially knowledgeable about commercial mortgage borrowers and commercial property markets, in that they have lower foreclosure rates than smaller lenders. Third, on the question of whether lenders have more information on larger borrowers than smaller borrowers, we find that larger loans have, on average, lower default rates than smaller loans. Fourth, the findings suggest that lower default rates are associated with higher debt service coverage ratios, both initial and contemporaneous. We find an insignificant relation between contemporaneous loan-to-value and default.
