Extensions are likely granted, if needed.You will receive $3k relocation assistance at the end ( unless you have other liens, back due water/sewer/HOA etc. ) You can also stay in the home until the sale closes, which gives you at least a few months payment free to be able to figure out where you will relocate.

I'm told a permit is required to replace a water heater.

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

I'd only look at land that's at least connected to water and power and already has a septic plan in place.

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

(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?

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.
