Couple things here....
1. do NOT scold him for going inside, when a dog runs from you with his tail between his legs that is sad and not a good reaction. He needs to simply be picked up and placed outside to go potty then praised for doing so.
2. forcing an indoor dog to be an outdoor dog will only depress the dog. Have you considered a doggy door? Stress and depression can lead to serious health problems and a dog who has been indoors for this long should not be suddenly thrown out.
3. The dog should be played with more than just "occasionally". Dogs need stimulation constantly. Try taking him outside a couple times a day and playing with him. He could be trying to get your guys' attention that he needs to go and is simply being ignored.
4. Has he been checked by a vet? If this is a recent occurance it sounds like a medical issue is the underlying problem, especially due to his age. Has his sight been checked? He sounds confused to be honest.
I find it odd your mother is more concerned about keeping her owned home clean but not the rented home...
