Hello bigger pockets community. I wonder if anyone has suggestions on how to handle a deteriorated lawn of a SFH property, in central Texas without sprinkler systems.

Tenant is maintaining the lawn by hiring a lawn maintenance service, including mowing and weeding. However due to the climate and without sprinkler systems, the lawn naturally deteriorates over the years and I start to get HOA requests to repair it. There are bare spots and dead grass and it is generally not dense at all. (grass type is Bermuda)

What's the best option to handle it? I don't know if I should go all the way to install sprinkler systems and new sod. It's a large corner lot and it could be a 10k investment, and I doubt tenant could water aggressively to keep it in good condition. Another option could be plant seeds but that too require aggressive watering for certain amount of time, and I don't know if a sprinkler system is a must for planted seeds to grow.

Let me know what do you think. any suggestions are appreciated.
