Poorly written contracts and a bad tenant.

[Allan R.]

Yesterday I purchased a property with 5 rental units. After closing I introduced myself to each unit and everyone was so friendly besides the trouble maker. She is absolutely out of control and insane. Asking the tenants how I could make their stay better, her two neighbors replied "get rid of her." 

The previous owner has her on a lease that makes no sense. It contradicts itself, has the date missing, and a spot for her driver's license number that also has not been filled out. Is this an invalid lease?

If it is an invalid lease what would be my next step? Do I have to offer her another contract?

[Thomas S.]

If it is signed it is legal. If there are no dates and no reference to term or a end point you assume it is M2M. You determine from the wording what restrictions you have in regards to enforcing the lease. If it is not signed it is a verbal M2M.  

You do not offer her a lease you simply non renew, with proper notice, at the end of what you determine is the end of her lease.
