If you are 62 or over (and not earning over the limit), you could file to start collecting your social security and save or invest it to start accumulating more cash. I think I'd wait on trying to sell your home until the market improves, but getting rid of the overhead on the lots is a good idea. Sit down and figure out a budget to cover your necessary living expenses, and sock away as much cash as you can in the next 2 years. If you have investments, sit down with your financial advisor and make sure that the investments you have are appropriate for your plans to retire. Is it possible for your husband to solict other consulting jobs, or plan to do so after his contract ends? It may not be possible to have the retirement of your dreams, but hopefully it can be comfortable.
