I will, however, cooperate with you regarding making appointments with tree trimmers, or roofing contractors, when the time comes.Please find additional copies of the photos of the limb enclosed.Most Sincerely,YouThen send it with delivery confirmation. 

so pretty much, by contract it's already "non-refundable" assuming there's no issues with delivery of property etc etc?

I've had two fridge deliveries from Lowes with slight dings in the front door and they've given me 15% off of one and 13% off of the other.

I then suggest you take the feed back from him along with the terms of the guarantees and delivery of financials and discuss with the folks you plan to have invest in this venture.

.: pizza delivery drivers, school bus drivers, lawn care staff, delivery drivers, junk men, mail delivery, etc.

Specifically look for a service that provide CASS (coding accuracy support system) address correction and DPV (delivery point validation), many also provide NCOA (change of address).

Send it certified mail so you have proof of delivery & if it comes back, too bad. 

For appliances you can just notify them you want to replace their stove etc. and when to expect delivery.  

I would just work on getting a non-residential mailing address in the near future so you won't have any crazy people showing up to your doorstep!

:) It's most always less about the substance and more about the delivery!
