He even had flower planting on one bill.

You just really don't want someone else telling you what kind of plant you can put on your porch when you're the owner, or choosing some god-awful color of paint for your building, on and on and on.I'll add another one - be sure and look at the property taxes. 

I'm going to assume your insurance is higher for having each pool.If you don't want tenants and their friends or locals gathering in a new park area, then just plant a bunch of cacti in there, close together, so nobody will want to hang out there. 

She says she loves plants and keeping the home clean etc.

I just planted extensive and expensive foliage at a triplex and the plants need daily watering now, and every other day watering for a few months.

I think for them they like the larger units and many have planted gardens in the back yards.

She has outdoor plants and such.

The plants are oily.

It is like having a bunch of strangers having the power to interfere with your investment.And then there are the board members who decide it's their mission in life to harass owners/tenants about every weird thing, like potted plants on the balcony or whatever.I only bought the one condo, intending to keep it forever and rent it out.  

I wouldn't bother putting in a lawn or do expensive landscaping because tenants cannot be relied on to water the grass or even trees and plants.
