I was told by the listing broker that the reason rents can be raised is that almost all of the tenants are due for renewal here soon, and the section 8 rents have risen as well.

I just use both CL and Zillow, as my ads are already set up and it's a cinch to renew.

My bank has been sending my HVAC guy an annual check for a preventive maintenance contract renewal automatically on March 15 for the past six years. 

The new upstairs tenants informed me they were looking for a house and would not be renewing their lease.

The Corelogic Repeat Rent Index (those renewing leases) is running at 5% nationally and anticipates a further 4-5% growth in 2015.Lack of available credit: Credit availability continues to be extremely tight.

There is also a possible clause for 'an option to renew'.

Perfectly reasonable to have it repaired before renewal.

I am renewing her lease and want to add to lawn upkeep that "sprinkler maintenance is tenants responsibility" and "any sprinkler valves problems will be maintained by landlord".

I have had tenants in it for 2 years and just renewed the same tenant for another year.Thanks for any suggestions.

All else being equal, the applicant that said she would hope to stay indefinitely (if the landlord allows through lease renewals) would be favorable to the applicant who plans to move after graduation or something.
