You should buy if your ramp needs are expected to be longer than 5-6 months because the rental can add up to be more than the purchase price. In cases where you are not sure how long you will need the ramp, we suggest that you start off renting. And if at any time it appears that you will be keeping the ramp, we will convert up to 75% of the rental paid and apply that toward your ramp purchase.
