Looks like I will go with Ellington -
1. Better school district
2. Natural gas available at the selected property (seems cheaper than Propane)
3. Can rent if not sold ( feasible with managed condo vs single family house )
I am not sure about these. As Ellington is as expensive as Vernon on taxes.
What it really boils down to is the specific location where the property is located. There are properties in Vernon which can fetch as high as the properties in Ellington.
Location has to be factored in primarily and the condition and features of the house.
There would always be a buyer who will be willing to pay for the asking price as long as it can be justifed depending on the factors mentioned above.
Home prices are market driven.
Do keep this in mind,
Best of Luck.
Have you asked your Realtor their thoughts? Looks like you are concerned about resale. If that is your number one concern, then make a business decision on resale. If you are looking for more room/price per square foot, then do what you need to accomodate your needs. You have to be comfortable and love where you are going to live. You need to trust your gut.
A pro/con list on each home will ultimately lead you to your best choice if you are looking to make a sound, business decision to really compare apples to apples.
