It's not just houses. It's pretty much anything. If it hasn't turned to dust it's good to go.
When I moved to La Plata 9 years ago I couldn't understand why the exteriors of the houses, and the hi-rise apartments were left dirty and neglected. Sidewalks, too, were left broken. Even the owners of properties that were for sale didn't bother to put on a fresh coat of paint. When we searched for a handyman to do odd fixups in our house, there were very, very few to be found and those we found were very sloppy about their work.
I've asked why this is and gotten a variety of answers but it seems like there's a shortsightedness, that money spent on maintenance is wasted.
We've since found two good repairmen and a very capable person to care for our gardens. When they finnish a days work they tell me what the cost is and I always give them 50% more or even double hoping that they'll return the next time we need them.
