I 'gave-up' and started farming...

It would take me roughly a week to get one additional plot of land. I only earn like 10k a day currently.

You don't earn as much $$ as you potentially could from your set-up, jarci1, if you cannot send your characters on repeated 1-hour tasks or get to collect from your houses and buildings at least a few times per day. Tapped Out! tends to reward those who can tap away at the game for extended periods of time or at various times of the day, each day.

As mdfriend suggests, use your imagination of what you would like your city to look like. In the cities of my childhood, for instance, we had neighborhoods with brownstone homes and rowhouses. None had their front entrances blocked by a front row of houses (smashed together), but there wasn't much light on their sides as space was at a premium in those areas. We did have small front yards or backyards, but the houses were all the same.

Perhaps after you've earned enough from your duplicate homes for you to feel comfortable buying land for expansions, you will decide to get rid of the duplicates as sonny1618 has said he's done if you feel they have become irrelevant.
