I absolutely love helping my clients buy their first home, sell their starters, upgrade to their next big adventure, or transition to their next phase of life. The confidence my clients have going into a transaction and through the whole process is one of the most rewarding aspects of practicing this type of law. My very first class in law school was property law, and let me tell you, this was like nothing I’d ever experienced. I remember vividly cracking open that big red book and staring at the pages not having the faintest idea what I was actually reading. Despite those initial scary moments, I grew to love property law. My obsession with real estate law was solidified when I was working in Virginia at a law firm outside DC. I ran the settlement (escrow) department and learned the ins and outs of transactions and the unique needs of the parties. My husband and I bought our first home in Virginia in 2012 and despite being an attorney, there was so much we didn’t know, especially when it came to our HOA and our mortgage. Our real estate agent was a wonderful resource for finding our home and negotiating some of the key terms, but there was something missing in the process. I’ve spent the last 10 years helping those who were in the same situation we were in better understand the process.
