Mercantile Bank is a Michigan home-purchase lender that ranks 6 of 436 lenders in Grand Rapids and gained share in three of its largest markets while its loan count held flat.
Gaining share across Michigan markets
Its share of Grand Rapids-Wyoming-Kentwood rose to 3.7% from 3.4%, behind Lake Michigan Credit Union in first place. It also rose in Kalamazoo-Portage, to 1.9% from 1.4%, and Lansing-East Lansing, to 1.0% from 0.6%, and it ranked 5 of 606 in non-metro Michigan. Traverse City was the exception, falling to 2.0% from 3.0%, which could reflect stronger years for competitors there.
Flat loan count, larger loans
Originations were flat at 2,129, a change of 0%, while similar lenders (state non-member banks making between half and twice as many loans) grew 13% and the whole market 10%. Dollar volume still rose to $622.0 million from $529.0 million, as its typical loan grew to $225,000 from $205,000.
Mostly home purchases
Home purchases made up 58.7% of its loans, refinances 20.4% and home improvement 12.5%. FHA loans (insured by the Federal Housing Administration) were 5.3%, against 3.4% at similar lenders, and up from 1.2% five years before.
Typical LMI borrower share, fewer loans in majority-minority areas
LMI (low- and moderate-income) borrowers received 27.9% of its loans, against 28.3% at similar lenders, near the middle. Its shares in LMI areas, 12.6% against 16.0%, and majority-minority areas, 3.6% against 10.0%, were lower than about three in four. The make-up of the Michigan markets it serves could account for this.
