I can't speak to your area specifically, but the answer really depends on how low you price it. For example, a Realtor can tell you average days on market for properties. That assumes the home is priced close to its comps, and that it shows well. In many areas of the country, that's anywhere from 45 to 90 days. However, days on market also tends to vary based on type of property (condo, townhouse, single family) and on the price range--with lower and moderate priced homes typically selling more quickly than large, luxury homes.
As you reduce your price below the comps, the house likely will sell faster. An investor, for example, would be in a position to buy your home in perhaps 15 days if you priced it at 65% of comps minus rehab costs. I'm not suggesting you do that, but that helps establish a range. Frankly, if your agent put it on the MLS at 65% of comps, I'd expect you'd have a contract in a week or less.
So your range is really anywhere from, say, 3 days up to whatever average days on market is for you--perhaps 60 days. The lower you go, the faster it'll sell.
Again, hopefully a Realtor familiar with Danbury will weigh in on average days on market.
