Great question! I have clients who just purchased a new construction home in Ashburn at One Loudon and I am familiar with the builders there. They placed an earnest money deposit of $25,000 on a home that was priced around $600,000, which is right around 5%. The builders may also want a deposit check for a percentage of the total costs of any upgrades you decide to add to your home as well. There are a few items and clauses in the builder's contracts that you have to watch out for - feel free to contact me if you would like to discuss the process.

For one, it's spring and that's when many sellers put their home on the market thinking it's the best time to sell. And you may also be noticing builders' home listings which are basically ads for new construction homes.
Another reason is that Stone Ridge is a fairly new community meaning that many people who bought in the community have not come to the "5 year" mark - the average number of years people in the DC metro area live in their home before moving once again. As the community matures, you'll see more people selling (and buying).
And you may have the new car syndrome - when you buy a new car, you seem to notice the same type of car everywhere you go even though you didn't notice it much before you bought it.
