Stress is a killer... seriously. So sad that you have to deal with the owners & their crap, but I guess it's all part and parcel of the terms for the property you're getting. Have to take the good with the bad... If the house was in perfect condition and the farm as well, you wouldn't be able to afford the purchase price, but the loan would be a "gimme". Lenders haven't "forgotten" the recent mortgage melt down and are still "scared" to do any loan that doesn't perfectly fit their refined definitions. To the best of my knowledge, the present owners do NOT have free access to the property once closing happens.
There should be a "walk through" the day of closing before the actual close for you, the buyers, to make sure that the sellers haven't removed anything that should have been included in the sale either by contract or by law (plumbing, electric, attached fixtures such as lighting, etc). They sellers should have removed all their personal belongings before closing and anything left behind becomes the property of the buyer unless specified in the purchase/sales contract. So their hoard becomes yours to deal with whether you wanted it or not. You can place a gate and lock it barring access to the property should you wish and with a no trespass sign/notice, they would be be in serious trouble if they entered the property and guilty of theft if they remove anything.
I hope the financing comes through for you, especially considering all the work you've already done toward property improvement. There is a lesson to be learned in all that somewhere...
