We found a few landlord related jokes around the web; apologies in advance!

A large family, with seven children, moved to a new city. 
They were having a difficult time finding an apartment to 
live in. Many apartments were large enough, but the landlords
objected to the large family. After several days of searching,
the father asked the mother to take the four younger children 
to visit the cemetery, while he took the older three to find 
an apartment.  After they had looked most of the morning they 
found a place that was just right.
  Then the landlord asked the usual question, \"How many children
do you have?\"
  The father answered with a deep sigh, \"Seven...but four are 
with their dear mother in the cemetery.\"
  He got the apartment!



  A man mentioned to his landlord about the tenants in the 
apartment over his. \"Many a night they stamp on the floor 
and shout till midnight.\"
  When the landlord asked if it bothered him, he replied, 
\"Not really, for I usually stay up and practice my trumpet 
till about that time most every night anyway.\"

 
 
  Long on egotism but short on cash, the young actor was trying
to talk his impatient landlord into waiting for the rent.
  \"In a few years,\" he said, \"people will point to this apartment 
and say \'Jones the famous actor, once lived there.\'\"
  \"If I don\'t get my rent tonight,\" said the landlord, \"they\'ll 
be able to say it tomorrow.\" 
 
 

  A group of American tourists were being guided through an ancient 
castle in Europe.
  \"This place,\" the guide told them, \"is 600 years old. Not a stone 
in it has been touched, nothing altered, nothing replaced in all 
those years.\"
  \"Well,\" said one woman dryly, \"they must have the same landlord 
I have.\"
