Negotiate or find New Tenant?

[Kay M.]

Hello, I have a situation where I've been renting to 3 roommates for 2 years on one lease. I increase rent $25/ mo each lease renewal year in order to keep the good tenants. This year one person is moving away, so the other 2 decided to give me 30 days notice. Now, they've asked me to consider lowering the rent $75/ mo in exchange for them renewing the lease with the possibility that if they find a 3rd roommate, I can increase the rent back to the original rent + the increase in rent.

My question is: Would you consider negotiating or try to find a new tenant in hopes of getting higher rent. What things would you consider?

Thanks for your time!
