The Founding Fathers only allowed landowners to vote because they were the taxpayers of the day (there wasn’t yet an income tax). I’d propose only letting taxpayers vote (regardless of how they contribute) - and I’m a homeowner. If you didn’t do that, then landowners would be deciding how non-landowners’ taxes were being spent - they’d be taxed without representation.
States determine who can vote, the Founders did not and left the electorate to the States as long as they are constitutional. There were even times when certain states allowed non-citizens to vote.
