@Blake C. , I would consider ways to not lose income first.
I considered this when my first leases were coming up. However, I had received 2 month deposits (1 month is market) - so I offered some of the deposit back.. I figured for $50/mo, I might as well take that as income, and I can use it to replace the deposit money if I can't get it from the remaining deposit or tenants. Of course, you still want them to have some skin in the game.
But if you're going to give up $100/mo, or $1200 for the year, why not give back $500ish in deposit, which might help them out after xmas? (if the place is well kept, and you want to keep them). Or why not pay for upgrades instead of just cash out of pocket? Offer to spend some money on an upgrade to the place, or something they want - that will stay attached at the unit. Is the bathroom old? Maybe a new vanity/mirror set? They love to cook? Maybe a nice backsplash, faucet, spice racks.. Fridge too small for their family? Sell the old one on CL and upgrade to a bigger fridge..
I would look at those options first. Shows you care, better bang for your buck, and hopefully should lengthen their tenancy by giving them something they need/want that will also provide benefit for a future tenant, reducing your turnove time in the process..
