Although, you get what you pay for & the Brownstones are much less $/per sf. than most builders out there.
If you want to purchase in the Hillsboro area there are many great buys out there right now...especially new construction. There isn't a builder out there right now that isn't offering an incentive to buy one of their homes.
I wouldn't say it's not "safe" to buy Brownstone Homes but always remember when you purchase a home it's an investment & you must consider the "resale" of the property....If you've heard bad things about the builder whose to say other buyer's haven't as well.
