Adjust least so tenants responsible for maintenance?

[Matthew Brand]

I am moving states and just have one rental property right now. I'd like to sell the property so I can invest in where I'm moving to and not deal with long-distance maintenance. My current renters have expressed interest in purchasing the property next spring (when they have enough money for a down payment). So, I'd prefer not to sell the house out from under them and just sell it to them in ~6 months.

I'm wondering what people have done in this situation? Could I potentially adjust the lease so that they pay $100 (or so) less per month and they're responsible for any maintenance issues? Other ideas?
