Personally, I don't see many BRRRRs that make any real sense in the neighborhoods I would be willing to own in, but I passively look at the MLS, so take my comments with a grain of salt.  

If anyone worth their salt would drill down at the micro level you could see the true impact. 

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. 

Bring a can of white spray paint with you if you feel the need to touch it up though unless you have exactly the same shade, it will leave marks.Evaluate each request on its own merit and decide if it needs to be done or if it can wait.

Does the spray can blend well with the rolled on product if there is a water stain to be covered?

Either way, I take these lists with a grain of salt.

Finally, two other things that you can look into or talk with your CPA to see if there could be any advantages to you (you may be phased out due to income for some) is the Section 199A pass-through deduction, which would require you to start tracking hours spent on your real estate enterprise, as well as the possible CA SALT tax workaround in case you were interested in deducting more than the $10k state and local tax cap for the next few years.If you need referrals for professionals in any of these areas in the San Diego area, feel free to reach out. 

A couple of the adjacent cities are planning on building 2500 new homes in the area...not sure of the impact as there is a water shortage due to salt water intrusion.  

But if you allow tenants to have pets it is not maintenance free and needs to be cleaned/sprayed down etc.

They age the barrels on ships at sea and it has a very complex flavor profile that is very salted caramely to me, I only drink it when I hit milestones or goals!
