Boy, what a mess! I'd be curious to know how this turned out. I live in 22405 and have 5 kids, too. We bought 12 acres of land back in 1993 and we built our own house while living in an 800 sq ft condo so I feel your pain! It only took us 4 1/2 months to build our house ourselves (acting as our own general contractor and hiring out subs to do the work) and that saved us a fortune. Of course, I'm anal with details and my husband is about the hardest working person I've ever met. I wouldn't recommend it for everyone, that's for sure.
Why did you say you couldn't sell? I guess I didn't understand that part....
Hope it all worked out,
