Kevin never rushed us, always seemed happy to show up and check a place out, and made the process easy. He worked well with our lender, worked well with our crazy five year old, and worked well with us when we ended up putting in an offer from out of state and having to figure out how to manage some of those complications. He checked in along the way and kept me posted at every turn. I would absolutely use Kevin again." Read Less
