it will take a while (years) for the value of the condo to return. also, when you look to sell keep in my financing will be depend on the occupancy (owners to renters).
so your potential buyer may be cash.

The housing marketing generally is pretty good in the D.C. area. Lots of areas (admittedly, I'm more familiar with Northern Virginia) have been showing strength over the last year or two. Here are a few stats for PG County: http://www.rbintel.com/statistics/prince-georges-county-md As you can see, year-over-year, median sales prices have risen 8.1%. Average days on market have fallen 25%. Sold-to-list price is 94%, an improvement from last year.
So, if by "normal" you mean that your condo will be valued at around $120,000 (and it's now valued at $18,000), probably not for 5 or more years. That's only a guess. A Realtor familiar with Suitland might be able to give you a somewhat more educated guess but, frankly, it'd still be a guess.
Hope that helps.
