Call some local oil companies and see if they had the address on their delivery records and if so was it an underground tank 

I think you should give option of fridge and let them know delivery is 3 days.. photo of the item from a big box store is all you need.. 

A new cistern is around $10,000 + water delivery for life and treatment is between $800-6,000 depending on who I believe plus ongoing maintenance and filter replacements.

I tried getting an amazon locker directly from amazon but I guess my location doesn’t qualify.Does anyone know and can recommend a package delivery/return system similar to the amazon locker, but that can work with all delivery vendors such as amazon, ups, fedex, usps, etc?

At least here in SoCal there is. consider 2 container fulls. we pay 500 for 40 yard here but we have delivery fees like 150/150 for pickup and dropoff

@Stephen Brown ,Typically, the PSA will spell out the most critical dates and then it is up to you to put them on your calendar or use an internal tracking system.Typically Timeline from my experience:Signed PSA = Open EscrowInitial Deposit = Due within 3-5 Business Days after Escrow Opens (subject to negotiation)Seller to delivery DD Items = Due within 5 Business Days after Escrow OpensPreliminary Title Report = Due within 5 Business Days after Escrow Opens and then you can negotiate how many days you have to object to any findings.Due Diligence = Due within 30 Days; Can be negotiable2nd Deposit Due = Upon removing DD ContingencyAppraisal = 45 Days after Escrow opensLoan = 60 Days after Escrow OpensClose Escrow = 60 DaysExtensions = To be exercised 15-30 days in advance of initial closing date (to be negotiated)I recommend you create a calendar, or use Folio as a Gmail add-in to keep track of your timelines.The main issue is that each deal has it's own timeline and you must be flexible in negotiations.

Changing the delivery address to Texas sets off an alarm.

@Nick Brown water wells have been sustaining most of the rural USA for decades...most of the time it's perfectly fine...the point is to have it inspected by a professional...if the well is viable you should be good...if there is a concern, weigh the options the inspector provides...the $500 for an inspection will save you $20k to dig a new well...Water delivery systems should be on your list too...there are several options on how you heat water and get it to your tenants plumbing fixtures...I would be interested to find out how you are billed for public sewer...if the city is not monitoring the amount of water coming in, how can you be billed for water going out??

Good quality and fast delivery.

You do run the risk of them not delivering on time or forgetting critical parts/pieces since they use a 3rd party delivery company.
