Things we've had flagged in the past are having dual sensor smoke detectors installed, all windows must open/close, torn window screens, functioning garage door, fire extinguisher present in kitchen, floors/walls must be in good repair, 2 prong outlets if no grounding wire is present, etc.

Although is fine to deliver a clean, functional  property and no more but  the OP wanted to do more on move in, my thought is link it to the property. 

@Brenda Henry from a functional perspective, the most important thing you can do is make sure they have the phone number and email you want them to use.

In response, the buyer can continue to negotiate, accept the seller’s position, or in some cases, end the transaction and recoup their earnest money.The buyer functionally removes or waives the inspection contingency by agreeing to a signed inspection response with the seller, or by failing to make an inspection response request to the seller before the number of days indicated in the contract has passed.Part 2: The mortgage processor those borrowing to purchase their home, the mortgage process is usually the the most stressful and opaque part of the transaction.

I posit that Cash Flow and the relationship that Equity has as a function of Cash is where one's focus should be.

Some questions though about the sale based on the bid process document that I received from my agentProperty Background: The property is fixer upper and is currently not livable (because kitchen is not functional) so I cannot get a conventional loan so planning to make an all cash offer.

Your housing systems: heat, electric, water, structure should all be functioning correctly - check those.
