Analyzing Comps before selling

[Account Closed]

Hello everyone,

I plan to sell my home sometime next year and I'm pretty confident that it will sell quickly. I know there are many homes in my neighborhood that have similar characteristics as mine for example, sqft, single story and build year.

At the moment there is a home across the street that is getting a complete remodel including a new roof but it is not going on the market.

My question is, how are increased value assessed on a property if it doesn't go to market?
