Accepting partial rent payments can lead to inconsistent income for landlords and may create confusion about the amount owed. It can also create a slippery slope where tenants continue to pay partial amounts, leading to a potentially difficult eviction process if the full amount is not paid. In some cities or states, for instance, if a landlord is trying to evict a tenant for non-payment of rent and they issue a pay or vacate notice, even if the tenant pays just $1, you need to start the eviction clock over. So if you have the option, consider not allowing partial rent payments.
