Reducing Rehab Costs - Materials Purchase

[Rudy Manna]

I am completing couple BRRRR in Washington, and 25% of the costs are in materials. I am buying some regular items such as cabinets, counter-tops, appliances, paints etc. All the purchases are primarily from local HomeDepot. What strategies people use to reduce material costs? I was thinking about exploring some new techniques. It will be super helpful to hear some real examples. I am trying to understand if it is even worth trying?

- Use the Marketplaces and buy used or new directly from customers such as OfferUP or FB Marketplace. or even Ebay.

- Hoard up during deals seasons. Such as, Buy 5 Appliances during thanksgiving. Garden supplies during end of Summer sales. 

- Buy from local thrift stores.

- Hire day labor to do relatively simple things like yard cleaning and basic landscaping, interior painting etc.

Thanks in advance. Some of those may sound like penny pinching but feels like they can add up significantly over time.
