Our high end units that we charge a premium for have ice makers and water dispenser.

When they are done, walk them through turning off any lights, locking all doors, and returning the key to the lockbox.Be sure to use the push-button numerical lockbox that connects the key to the removable access face-plate, rather than the kind that dispenses the key all by itself.

I was thinking of making a automatic dispenser so if anyone did break into the house, it will dispense the smell all though the house.

However, that can be cumbersome to deal with as they have to take care of everything for you - ie) checking the investment and dispensing funds.  

I would also verify the zoning.The first 18K would be used to clear all liens and then I would dispense 10K at a time and verify work is being completed. 

I know in our own home, having an ice maker/dispenser in the fridge door is an important convenience.

The title company will never issue title insurance because they can't guarantee all "heirs" have been accounted for and money from the sale has to be dispensed according to law anyway.Have the guy in the back of the house sleeping in the bombed out 1971 Ford Pinto with the Jack Daniels, give you the names and contact information of one or two of the other "heirs" so you can get to the bottom of things.

I buy those poison dispensers where the bait is in a plastic housing that the mice can get in but kids can't access the poison.
