A relative found out recently that the lawyer who recorded a lien for them put his law office as the notification address, not their home address.  10 years later when the guy stopped paying, they found out from the records' office that the home foreclosed and they never received notice because it went to the lawyer's office, now non-existent, not their home. 

They use heavy duty, high speed special printers that cost anywhere between $15,000~$30,000 depending on the model (which I've considered buying), not to mention the type of font they use, as well as how the ink prints on the paper they use, also being different than the ones retail buyers have access to. 

So the seller stopped paying the taxes and the property went to tax sale, where nobody would bid on the property except one person who bid the minimum bid. 

I think the mindset is that the worst they do is call you and ask you to stop.

Meet people face to face for sure.If you see a house being flipped, stop Car and meet the contractor!

@Collin S.Either have the guests clean up after themselves, or hire a cleaning company that will stop in take care of bedding and towels and such.How close do you live near the property?

I drive a lot for work and figure just to be able to get into key lock boxes (after checking with listing agent of course) it would be nice along with the access to mls.

You will gain respect, contacts you would never have access to and a behind the curtain view that no paid guru will offer.  

Knowing everyone is busy and not wanting to waste anyones time, how do YOU deal with securing access to the property so you don't have to ask the owner to stop by each time your contractors need in to do the walkthrough and write up a quote?

Stop giving them choices and tell them how it is going to be.
