Defendant Perlman purchased lumber to the value of $38,747.09 at cash prices. Defendant Perlman gave a first mortgage on the premises to defendant United States Mortgage Bond Company, Ltd., for $175,000 and a second mortgage to plaintiff for $33,000. Defendant Perlman did not pay in cash within 30 days the cost of materials furnished by plaintiff in excess of $30,000 at cash prices. Plaintiff claimed a lien on the premises for materials furnished for $8,747.09, filed a bill to establish and foreclose the same, obtained a decree for $9,348.46, being the amount claimed with interest, and at that figure, plus costs, defendant United States Mortgage Bond Company, Ltd., purchased the premises. Prior to the commencement of this suit plaintiff's mortgage had been reduced by payments thereon to $24,000, when default was made in further payments, and the bill herein was filed July 12, 1927, to foreclose the second mortgage. There was decree for plaintiff for $28,363.92 and defendants appeal.

The sole question is, was the mortgage usurious? If so, plaintiff cannot recover interest. Section 5998, 2 Comp. Laws 1915. Plaintiff had a right to charge more for its lumber sold on credit than when sold for cash. That it did so does not render the mortgage herein usurious. Rosen v. Rosen, 159 Mich. 72 (134 Am. St. Rep. 712); 39 Cyc. p. 926; 27 R. C. L. p. 214; 28 L.R.A. (N.S.) 102, note.

Decree affirmed, with costs to plaintiff.
