Great choice of locations! I've been spending a lot of time in SW with clients! It's a great area that has really taken off and now that development is continuing it should just get better and better.
Your question is difficult to answer with such basic information. Not only does it depend on the exact location, age, SF, condition, features, building amenities, condo fee, proximity to metro and shopping, etc. And there are many more!
If you are serious about purchasing, it's best to work with an experienced buyer's agent who can guide you through the process. Some first time buyers don't realize that the seller pays both sides of the brokerage commission and that there's no cost to the buyer. Some buyers think they'll get a better deal without an agent. That's very rarely true. I spent many years as a top builder sales rep and I can tell you that an unrepresented buyer really helps seller profits rise! Not only will you be at a big disadvantage in negotiating with a builder rep, you're likely to be unaware of the protections and steps in a savvy resale or new home sale transaction that will not only save you time, grief and money not only during the sales process, but long afterward.
Whatever you decide to do, I hope it is successful for you!
I did run a few reports of actives and recently solds.
There are a couple of "outliers" (above $300,000), mostly in one complex at 1101 3rd St. If you exclude those, there have been 20 solds in the past 180 days--minimum was $155,000, maximum was $279,000, average was $222,465. So you can see there's an awfully wide range. Those are for 1 bedroom condos in 20024 without parking.
What you need to do is contact a Realtor and have him/her do a CMA on the specific unit you're interested in, or at least on the building you're interested in.
Hope that helps.
I am a Realtor who live and work in the SW Waterfront area. It's a great area with 1BR condos and coops from $150-$400K. If you want a direct water view it may cost between $175-$250K depending on the square footage and the building. There are only three buildings with direct water views. Sometimes, the best properties do not make it to the public market because buyers have realtors who leave and work in the Waterfront area scouting sellers. I have a 1BR that I will put on the market next month for approximately $187K. If you are interested, or if you want me to put you in my database please contact me at Reone@ivanbrownrealty.com. I also keep an ad in the Southwester publication which is also online. If you are a first time home buyer in DC you can get down payment assistance as well. I hope this information was helpful, and you mayu want to attend one of my homebuyer seminars at the 1st District Police Station in SW.
