If the seller is just wanting to unload all 3 and you're getting a bulk discount, you can always wholesale whatever you don't want to another investor.

Great drive-through lumber yard (at my last one, anyway) and I prefer to just load it into the car, rather than steer those carts around the store. 

If you are thinking of leaving, make sure you can rent it and don't have to unload it immediately.

Buying a bulk of properties wholesale and determining which avenue to unload the properties is where I am right now.

Also, I've heard good things about Lumber Liquidators. 

Are there any tips/tricks on saving on lumber costs from suppliers?

My pleasure @Tyler Divine...1) Essentially same advice as posted about in your lumber purchasing post... detail the scope of work, specify fixtures or state the allowance for them, and review all bids to ensure apples to apples.2) Funny you should ask about poor soils, as I was recently consulted by a builder on this very topic as they didn't perform soil tests prior to acquisition and excavation and spent upwards of $70K on the fix!

I would need to build a relationship with a Realtor looking to unload some properties since the market has picked up here significantly from what I've seen.

It's like giving profit to your lumber guy, when you build the furniture.

Find something that's a foreclosure or other bank-owned, or someone really needing to unload, that just needs cosmetics rather than structural, in a reasonably healthy community.
