In reviewing a determination made after a nonjury trial, the power of this court is as broad as that of the trial court, and this court may render the judgment it finds warranted by the facts, bearing in mind that the determination of a trier of fact as to issues of credibility is given substantial deference, as a trial court's opportunity to observe and evaluate the testimony and demeanor of the witnesses affords it a better perspective from which to assess their credibility (see Northern Westchester Professional Park Assoc. v Town of Bedford, 60 NY2d 492, 499 [1983]; Hamilton v Blackwood, 85 AD3d 1116 [2011]; Zeltser v Sacerdote, 52 AD3d 824, 826 [*2][2008]).
