After analyzing several neighborhoods (Daniel Park, Hamilton Mill, Chateau Elan, Trilogy Park, Hidden Falls and Gwinnett County as a whole) it became increasingly evident that new construction is going to be a force to be reckoned with in the coming months. The success after the turn of the summer for 2013 and the upcoming new builds that are coming will compete directly with home owners at the start of the year and spring. It should create a sense of urgency for home owners in these neighborhoods that are hoping to sell. (To answer the questions, "What is my home worth?" go here. )
With over 250 homes labeled as new construction homes in Gwinnett County, it's no wonder why prices of resales are going to be effected by builders.
Overall, my opinion is that prices will continue to rise but on a slower path and although the county will see a large increase in average sales price next year, I don't believe it will be from resales but rather new construction. If you were timing the market, NOW would be the best time to resell your current home and move up into another home, particularly if you are in Daniel Park or Hamilton Mill.
