About The Broker


Marc Dosik Broker  
Marc Dosik, Broker/Owner


As far as I’m concerned, the buck stops with me.  As the principal broker at Help-U-Sell Federal City Realty, I can make things happen quickly.  You’ll have easy access to the primary decision-maker for any transaction.

I’ve been happily married for 20 years, and I teach my two children my philosophy of life: The only thing you can take with you is your integrity and impact on others.  It’s a philosophy that I believe in, and it’s served me well in business and in life.

I’ve been a resident of the Washington DC metro area all my life.  I know the market and the neighborhoods. When you are buying or selling, you’ll benefit from the extensive network of trusted professionals I’ve nurtured over the years.  Working with trusted professionals will simplify your life during the transaction, and afterward too.

I’ve been a licensed broker since 1998. Over that time, I’ve developed an extensive knowledge of how real estate transactions and contracts work, and the negotiation skills to back up that knowledge. I’ll go to bat for our clients every time – even if it means going to the CEO of a mortgage company to push a deal through. We stay focused on your best interest.  We give you the time and information you need to make the best real estate decision. We’re glad to answer your questions, and you’ll find us to be good companions during your next real estate transaction. You’ll find our response times to be extremely quick.  In real estate, time is usually of the essence, and you’ll find we won’t keep you waiting.

If you’re relocating to the DC area, you may not know exactly where to find the neighborhood and lifestyle that meets your needs. We can help you narrow down your search to the right locations in DC, or the close-in neighborhoods of Maryland and Virginia.

Our goal is to exceed your expectations, and we work hard to meet that goal.



  • For Buyers: We are licensed in all three local jurisdictions: DC, Maryland and Virginia, for one-stop shopping.  We look forward to helping you find just the right property, for home or investment.
  • For Sellers: We sell homes for a $7,950 Flat Fee!  So we can save you money.  The seller of a typical $400,000 home saves approximately $14,000 over what they would pay a realtor who charges a 6% commission.  In this economy, that can make all the difference!  And we provide the same full service.

Don't just take our word for it.  Read what our Past Clients have said in their testimonial reviews.  We're proud of the reputation we have earned, one client at a time.
