It's not uncommon for home buyers to have existing leases they need to honor themselves, and other considerations, that necessitate waiting a couple of months before moving.Finally, as a landlord, be very careful not to use (or even sound like you're considering) age, familial status, or disability as factors in tenant selection.

Not an uncommon scenario in a rental, even for the most well meaning landlord.

Mark,That's not uncommon.

It is not totally uncommon for a company to pay the rent for one of its employees but I would say that you still MUST do your due dillegence on the TENANT that will be occupying the property.

It isn't uncommon to get a pretty good hail dump and that, as you may know, will cause havoc to roof and vinyl siding. 

That is not uncommon as @Dawn Anastasi stated.

Sue K. it is not uncommon when there is a distressed property for the selling agent to look for offers as-is with no inspection.

It's not uncommon that to successfully have a restraining order placed on someone, you may be asked to accept a reciprocal restraint on yourself. 

Moldy undersink is not uncommon, and happens more often than not.Any tennant which won't let you do a walk through for emergency repairs has to be removed.

It is not uncommon for inherited tenants to be a problem and evictions are common.
