Do your own due diligence, but I have been impressed with their customer service and responsiveness.  

It's not relevant, as Mark says.

But you're a good customer - how about a rebuild?

I am also aware of the red tape and bureaucracies that big banks put in place to protect themselves that are cumbersome on people like me and my customers, who don't fit the mold of the "typical" buyer.

The homes are custom built, so there is a combination of vacant lots and custom built homes.

No offense intended, but your question has been answered many times before, but I'll contribute again....Contracts are unique to your area and need to comply with local custom, so get ther reviewed by a quaified person, which is not a guru.Addendums may be written on the spot and added to a base contract, but you need some contract knowledge to write any part of a contract, especially when you modify the basic contract.

From a methodology perspective, I'm using the relevant fields of 362,386 county property card records in a series of queries to obtain the results.

I tried to call customer service but was on hold for over 15 minutes before I just hung up.

Realtors are bound by a myriad of rules , customs and courtesiess.
