yeah you DEFINITELY take prorated dollar amount for the extra 7 days and then set the new move dates with both parties.

A couple of follow up questions:1) Are inspections completed by a city inspector or a 3rd party and are there any expenses associated with that?

@Aryelle Collins I'm late to this party, but you should be able to just use listsource.com. 

Not because of anything she did but rather another party to the transaction.  

Just trying to be conservative on that amount.

On the other hand, I think that long-lasting relationships are built on deals getting done, and mutual benefits to both parties - not just on contractual commitments to work with someone if something gets found..

The interested parties (homeowner, mortgage co or lien holder) have the right to redeem the property all the way up until the tax sale foreclosure case has been completed (Judge signs order).

Buyer has examined the Premises and is relying solely upon such examination with respect to the condition, character and size of the land, improvements and fixtures, if any, constituting the Premises.At Buyer's own cost and expense, Buyer shall obtain and maintain in full force and effect at all times during the continuance of this Contract: (a) comprehensive liability insurance for bodily injury or death to any person or persons, and property damage insurance, in such amounts as Seller reasonably deems necessary; and (b) fire and extended coverage insurance in an amount sufficient to prevent Seller from being a co-insured under said policy of insurance, but in no event less than the unpaid balance due under this Contract.Seller and Buyer shall both be named as insured parties in the insurance policies required above, as their interests appear, Buyer shall furnish Seller with memorandum copies of such insurance policies upon Seller's execution of this Contract.

I generally use the first scenario "A" for the asking price and a conservative rental amount.  

Do you consider your personal emergency fund as money that can cover these costs, or do you stay conservative and have a separate sum set aside?
