The best system will include today, soaker hoses to water foundation, not just spray heads.If there is no sprinkler, I would think it is not easy or cheap to hire someone to water. 

My roof water leak test could not reproduce the leak albeit the amount of water from a garden hose can't compare to a major rainfall. 

Look for signs of water damage, like stains or discoloration on walls.Roof problems are also common.

If after adding the additional monthly recurring costs (electricity, gas, water, internet, insurance, lawn care, snow plowing, etc.) to the standard long-term costs (Mortgage, taxes, regular insurance, etc.) the property won't net at least $100 if I can get the average rent I see on FF for that area, then the property isn't worth more investigation.

I've been introduced to GDL Asset Management/Green Water Asset Management, which primarily focuses on multifamily properties in Arizona.

Be aware of the costs as you'd need plumbing (water and sewer), electric and possibly a separate meter to the new unit.

I sell real estate to STR investors in a beach market, and one of the main strategies I tell them about (and that I also use myself) is to have a new 4-point inspection and a new wind mitigation report done periodically and to reshop insurance with a few BROKERS.In Florida, these inspections are only good for 1 and 5 years, respectively, so you MUST get new ones--especially if you have had a new roof, added hurricane clips to an existing roof, or replaced your wiring, HVAC, water heater, etc.Also in FL, insurance companies come and go, so there is no need to stick with the same one and just take it when they try to bend you over and raise your rates. 

Your tenant sends you a video of a burst water line.

I’ve been investing in Tampa for 20 years, and right now is a perfect time to buy with panicking sellers and the market cooling a bit before rates improve and the tide turns again.
