How long do you intend to live in the home? Will it be an investment or primary residence? If it's a purely a financial decision and not emotional, then you will have to go back to prior years to evaluate the appreciation because the number of homes sold is so few in this price range.
If it is your primary home and you intend to stay there for many years, then all 3 areas are viable for appreciation. Since they offer different things, I suggest you find the area and homes you love and then decide on a price that reflects it's current market value.
Using a experienced realtor is the key to guiding you toward a property that makes sense for you and your family.
if you would like to have that discussion with me feel free to make contact. If you have a Realtor already that you are happy with then have that discussion with him / her.
RPM has a great footprint in this area. If you would like a referral for Realtors who could help answer this question, please let me know.
Let me clarify something else as well - the people who buy a home because they love it regardless of where it is are usually much happier with their decision and their home than those who try to buy a home as a wise investment. It's the difference between buying a house with your head and buying with your heart. At the end of the day, buying a home isn't supposed to be about potential appreciation: it should be about quality of life, about having a roof over your head and being in love with both your home and your new neighborhood.
And, if you happen to get great appreciation as well, that's the icing on the cake ... not the cake itself.
