Rental agreement mistake

1.  Talk to the tenant once and point out the mistake, suggest a rectification/ amendment of the agreement.

2.   If he refuses file for rectification legal correction of contract or terminate his tenancy with proper notice. 20025 mistake doesn't automatically cancel the agreement, it will likely be read as 2025.

Prima- facieyour worry seems genine. A concrete view canbe formed only by seeing the paper. 

To my understanding, there is no correlation between the obvious mistake of year mentioned as 20025 and the alleged mistake of monthly rent being mentioned as 7000 including rent. The latter aspect is a question of fact which could be settled through mutual negotiation and amicable settlement or a civil action or arbitration (if the agreement provides so). Any contract is voidable in case of mistake of fact, but not per se void.

The mistake in the year is typo error hence cannot render the agreement void, however you cannot take shelter under this for not reading the agreement conditions properly.

You can sort it out by negotiations only.
