A linear probability model is desirable because effects are risk differences, which are much easier to interpret than odds ratios. It's best for proportions that are not too close to 0 or 1; otherwise the model may predict probabilities outside those boundaries. (In this range linear, probit, and logit models give similar predictions-Cox, Analysis of Binary Data, 1972).
