Not a great position to be in if the market dips, and a issue cash flowers don't have as rents are a lot stickier against market movement the the volatility of sales prices.

As a side note, I just closed on this house about a month ago- within a week, these tenants have already planted flowers and landscaping...  

We cleared and planted about 300 fruit trees and flowers on it. 

Should I go over and move the stones and dig up flowers?

I purchased landscaping bricks to go around the home, put mulch in the flower beds, removed a ton of debris (old roots and stumps) from the flower beds and manicured the yard to perfection.

Some of my costs are photography, pamphlets, sign placement, utility company marking utility for sign placement, placing it on the electronic lockbox system, I usually do a little bit of landscaping..mulch and flowers, depending on the price point of the property I might also need to pay for staging and professional maid service.  

Give her a second notice and hope she pays then a month from now when she doesn’t, give her a third quit or pay notice as well and buy her flowers and say “pretty please “and maybe she will pay part of Mays rent .

Can you compromise by planting flowers and using mulch rather than sod?

Maybe painting, carpet cleaning, new flooring, fountains, flowers, etc. 

@Rajeev Kotyan, Thanks for the input...it's like a beautiful field of flowers planted atop landmines.
