What to do, how to do it?

Well, heres a true story. Hubby aunt and uncle passed away, his aunt latter, and they left a will, and the executors are going to follow it, but there is a problem. Hubbys dad passed away many years ago, and its the farm where he was born. We would love to buy the farm off the estate, but it was valued at 450K, it has a house and some sheds, and 35 acres which would be fantastic to us, though we would have to put up some new sheds and house would need to be modernized and it would take a bit extra. Our credit sucks as we hit some hard times, but we have been good for a year. What would you do? The farm has been in his family in Kerry for close on 200 years, we are not beneficiaries, but at the same time would like to keep something going. What options do you think are open to us.
