@Rob Birch being both in commercial real estate and an investor in a landscaping company, I have some firsthand insights that hopefully will be helpful.
From the perspective of an investor or syndicator, the appeal of xeriscaping is the reduction in water usage, landscaping maintenance costs (no more recurring weekly or bi-weekly mowing and shrub maintenance costs), and an overall clean appearance that requires fewer inputs and less time to keep looking clean and polished for residents and touring potential lessees. These can all be had if the execution is done properly.
That being said, xeriscaping does also have a few *potential* drawbacks. First off, it can be incredibly costly to install. I cannot speak firsthand on a large multifamily property as our guys have never done anything larger than 4-unit properties, but I could easily see it reaching into the six-figures very quickly for a reputable company to do the prep work and install.
Once installed, it can be fantastic and last for years without needing extensive work to maintain it. The key is finding an installer who is skilled and ensures that it is done properly. Since the craze that really took off in 2018, we are already seeing lots of xeriscaped properties that have been overgrown with weeds, washed away down to the soil, or blown away down to weed barrier. If you can find someone who will ensure it is done properly with a plan to mitigate extreme erosion from rains and winds, and who will make sure that all preventative steps are taking to reduce the volume of weeds that pop through, then I can see it being quite advantageous.
PROS:
-Looks really nice, especially here in Texas where it goes with the whole "southwest" vibe we've got going on.
-Reduces input costs (fewer amendments needed for fertility and growth, much less water usage)
-Easy to maintain and keep clean
CONS:
-Can be very expensive to install properly
-Erosion can be a serious problem if you get significant winds or rainfall and don't have a plan for how to handle it
-If installed incorrectly, it ends up being more of a money pit than maintaining a lush green landscape.
What's the current water usage like on the property you're considering for transitioning over to xeriscape? Not exactly sure what the precise threshold is for it making financial sense, but I imagine with 3-4 bids and historical landscaping water usage data you could analyze how long it would take for it to pay for itself. Happy to hop on a call if you have any questions or want to spitball on the subject--we've had some good luck getting approved to drill irrigation wells (even in cities) for multifamily properties, essentially trading out years of high watering bills for one bigger upfront cost to get the system switched to well water. Not sure if this is a possibility at that property, but definitely worth looking into simply due to the allure of nice lush grass when seeking to attract renters.
All the best and keep us in the loop how things are going!
