Purchasing scratch and dent/repaired appliances from Lowes?

[Gil Lieblich]

I was searching for appliances for a foreclosure property i bought and i was speaking to another investor who said he goes to the lowes and depot and every week looking for good deals and keeps back up items as he owns many properties and constantly needs to replace things.
So I made some calls and contacted the store manager at a local lowes as they seem to have the largest supplies and asked them to find me scratch and dents/ repaired or discontinued appliances. They found me most at a substantial discount and in the end I got a fridge, stove, microwave, dishwasher, washer dryer for under $2000. (even stainless steel dishwasher and front load washer dryers)
Is there any reason i should not do this for future rentals?
