She called yesterday and said she needs to unload the property.

Even though this is lumber, I count it as part of the foundation budget as this is the platform you are going to build on top of.Texas has termites, so every foundation needs to be treated for them. 

If I pursue the property, I'm hoping the family wouldn't mind unloading the house cheaper for a couple thousand cash upfront and talk to them about owner financing (if that's a good idea, need to review that topic) since no one actually lives there.

I've had fir trees removed and broke even by selling them to a lumber mill.  

Even if it was unloaded it makes for quite a blunt object.It's kind of like putting up signs that say "this area is being watched by cameras".

Lumber is a commodity and moves with the market.

agree all our plumbers and electricians have those.. the carpenters tend to have the trucks with lock storage bins so they can haul lumber.. one thing i had when i was big into rehab.. and was really a good tool is a dual axel dump trailer with a hydraulic lift ..

Maybe it's the non-descripted guy at Home Depot loading lumber into a truck with no logo on the side. 

Was brought to our attention by a realtor who had an out-of-state landlord looking to unload.

Talk to a local lumber yard.
