As far as water goes, you could put in a well (make sure you have a way to get water out of it if you are without electricity), put in as many rain barrels as possible (don't forget about putting them on out buildings too), stash as much bottled water as you can and then you also have the creek. If you do all of those things, you should be okay. I would also get a Berkey t0 make sure all that water is safe to drink. Wooded area is important for several reasons. It provides a blind against traffic and people passing by, it provides a habitat for wildlife (which are a food source) and it is also a source of firewood for heating and cooking. As far as security goes, you are always at a risk unless you are in a hidden underground bunker. I would fortify my home as much as possible. I have been living in Italy and France for the last couple of months. I am sooooo glad to be home but I tried to observe some of the things they did there for security and self sufficiency so that I could adapt them for my own use here in Texas. One thing that almost every business and homeowner does is install the rolling metal door and window coverings. One of my friends in France told me that it was almost impossible to get insurance if you didn't have them on your home or business. They also use metal, slate or tile roofs which can last hundreds of years and are fireproof. They also use all the stones that they gather on their property while preparing land for farming or clearing an area to build a structure and use them to build fences, walls and buildings. They aren't beautiful stones, uniform in size or even very large. Some of the stones are quite small but they use them anyway. Many of the structures last for centuries. They have tons of hoop houses and greenhouses and garden year round. If SHTF or the power grid is compromised, power (electricity, gas and phone service) will be impossible to get. I would try to start putting in a solar system and add to it as finances permit. In choosing a home, you would need to make sure that either your roof is situated in a way that installing solar panels would be possible or that you have cleared land near you home that could accommodate solar panels. Land layout is really important. Are you going to have livestock? Will they have access to pasture for grazing? Is that pasture near that creek so they have a water source or are you going to put in portable tanks for them? I'd take pen to paper. Sketch out all three properties on paper and design how you would lay out the properties. Where will the outbuildings go, where would the garden go, where would the cattle go? I'd look at ways that you might be able to better secure your property. Can you dig a ditch where people may be able to access the property? You could install a type of cattle guard over it so that you could drive across it and then remove the guard when you don't want people to be able to drive across it. I would also consider price. If one property is much cheaper and would make it more affordable to make needed improvements, I would consider that when making my choice. Also look at the community. Being close to family or like minded families is really important. Just remember that whatever home or property that you choose, you can always improve on it as money and time allows. Good luck to you.
