Mark is great. He has problems taken care of quickly and never bothers us. He really appreciates a good tenant and is good in return.
Update: We did have a bit of a problem after moving out getting our security deposit back. Mark told us that money was tight and kept putting off giving us our deposit. Landlords are legally required to put security deposits in escrow accounts so it doesn't get mixed with business money. After requesting it several times and then a sternly worded message we finally got our deposit back.
