Due to the >15% delinquency rate this specific condominium is not "warrantable", meaning you'll have to find non-FHA, VA, Fannie Mae or Freddie Mac loan programs - leaving "non-conforming" loan programs or "portfolio" lenders as the only options. There certainly are those types of lenders in the DC/VA area, however they will also have requirements for their condominiums, perhaps they'd allow a higher delinquency rate, but essentially 1 out of ever 3 unit owners is past due on their HOA dues... if the HOA doesn't have adequate reserves to weather this financial storm that is happening then the HOA complex could have extreme financial difficulties in the future. However if the condominium as a whole improves financially, less owners are delinquent on HOA fees, etc. it could turn from a non-warrantable condominium (lower demand) into a warrantable condominium (higher demand) and increase the home's value just because the pool of available buyers has opened up.
I'd recommend you read up on Rebecca Law's blog regarding "How to X-Ray an HOA" (Rebecca is a real estate agent in Minneapolis), it's a 9 part series (each part is short) on the items you really should consider when purchasing a condominium or any home that is part of an HOA. It gives you a lot of food for thought.
