If you dont' already know the landlord-tenant laws, you should learn them and find out if there are any restrictions on how much you can raise the rents or how often, etc.I highly suggest the Nolo Press landlord books. 

I really like the contracts by Nolo Press. 

Nolo Press books are great and are cheap, but there's also a lot of good free info written by lawyers on their website:https://www.nolo.com/

Agree about Nolo Press.

Once you learn this, you can press the reset button and start over with a new strategy for dealing with any tenant.

I'm not about to disconnect myself from my investments because I read one article in the press about some landlord getting killed either.The day I feel uneasy about turning up to collect rent, is the day everything gets sold and I buy a boat.And yes, there are time I carry.

or were you pressed for time when you took this rental and did not consider it fully?  

I love Nolo Press books. 

I think you can hire a property manager for your  first year when you are learning and you seem pressed for time.

If pressed, I'd say the reason is being deceitful and untruthful in general.
