Make your expectations clear and simple.Two clauses I really like after having issues with couples breaking up or singles disappearing:In the event that Tenants decide they no longer want to live together, ___________ will be considered the primary Tenant to make decisions about modifying or terminating tenancy.

How do I modify a residential lease to a create rent by the room leases for each occupant?

A fair amount to agree upon although I foresee a few major looming modifiers that I predict have a high degree of likelihood in happening that have strong influence in adjusting markets. - The correlation of erosion to buyers purchasing power in monthly mortgage payment (increased property tax's, property insurance, HOA fee's) is a factor I see counter acting a slowly declining interest rate, making for a ~net-0 market activity environment on YOY volume metric. - Leading into home stretch of POTUS election cycle, the above may be a strong catalyst to press the deployment of a stimulus offering in form of home buyer empowerment

You can either make your new lease expire at the same time as their old lease - so you can modify your rental rate then; or you can bake a new rental rate into your lease at the time their old lease would have expired - so something like "Through X date your rental rate is the old rate, and beginning the next month your new lease rate is X $ more.All the best!

Approached the right way, you may have a chance of modifying their requests to be more reasonable and ones you can work with.

Or do you rely on the buyer in the area to assess the damage and modify the offer accordingly?

What @Tim Baldwin said.Otherwise, spend some time figuring out how to edit your existing lease to make it MTM.FYI - our company lease is setup to be ANY lease length by just modifying the lease term.
