Renters Warehouse forgot to include lease term& expiration

[Joseph Parker]

The lease was signed by all parties back in July 2019. I have an issue with tenants (they co-signed the lease and now aren't getting along). Everything else seems to be filled in, just not those two fields.  Honestly, I signed the lease as the property owner without noticing that those fields were missing, so that's on me; but it should have never gotten to me with the term being defined. Crazy. 

What's more concerning is that I actually had to fire Renter's Warehouse in December because they were awful about managing the property - bad communication with both me and the tenants, bad service request performance, lack of detail on service costs. So they are no longer the management company; I am acting as the landlord. I have not pointed out the missing info from the lease to the tenants yet; I want to know where I sit from a legal perspective first. 

My questions for the group is (preferably anyone who is an attorney in this field): 

1. Is the lease even valid without a term or an expiration?
2. What liability do I have?
3. What is Renters Warehouse liability?
