(Making judgements based on family status, number of kids, medical animals, etc etc..)4) When you get that first repair call 10pm Saturday night for a leaking roof or water heater do you have a trusted/dependable guy to call and get it fixed that night?

One of the tenants hung a picture on a wall, puncturing a water pipe.

I guess my other understanding is that I have to provide it is water proof and it is correctly zone for fire.

They almost flooded the entire ceiling the first day because they couldn't even figure out how to turn the water all the way off.I am looking for an answer on how I can deal with this.

You mentioned the roof and AC being new and i'm assuming they're in good condition.10% should be enough to cover the random water heater that goes or any other lesser headache. 

I know the 20yr city development plans, I know of the waste water treatment facilities that are wrapping up approvals and have not even broke ground yet and exactly how many w/s laterals will be approved with such. 

I recall when I first dipped my toes into out-of-state properties; it felt like navigating uncharted waters, but it opened up some incredible opportunities.Between BRRRR and turnkey, it really boils down to how hands-on you want to be.

However, upon finally gaining access to the home it appeared that the water was running from every faucet in the house.

The biggest danger is a leaking tank that causes water damage, but it hasn't happened to me yet.

I have a lot I have purchased in Cancun and am needing to submit plans for the construction of the home itself fairly soon and am like a fish out of water.
