Realtors often think that lenders only "take" without giving back and this is a way to give back to your realtor partners.I also love the idea of cobranding or promoting realtors in different markets.   

So I am looking for information on what to use as the base/patio material. 

I'm located in Dallas so the labor cost and materials may be different but you can get an idea at least.

The plan: I am identifying on/off market properties that are targets, will do all of the real estate work (listing, showing, advertising, vetting, etc) and will split the cost of the purchase of the home and the material costs for any needed repairs.The contractor will be subbing out portions of the job and be on site mostly full time until the project is completed. 

Have you ever ordered bulk materials from there?

Pay for labor only per job and cover the material cost yourself.

BP must be getting paid somehow to promote the terrible software.

Keeping your payments artificially low seems great until you need the coverage and there is non because you made a material mis-representation in the contract.

Rail road ties will be considered hazardous material in many states now .

Let's face it, a lot of what you write, and you write a lot, is about promoting what you do.
