Best strategy for using credit card rewards for rehabs?

[Matt Ridenour]

Hi community!

I'm starting my 4th rehab this year and I'm finally getting around to trying to figure out how to best use credit to do this.  So far I've paid cash for my rehabs, totaling about 70k.  Was listening to Rondi Lambeth's podcast and it got me to thinking that I should be using credit more as a tool.  

My next rehab is going to be about 50k and I'd like to maximize my points. Currently my only rewards card is an AMEX with a 3% cash back deal.  I started looking at Lowe's business account, but it's only 5% savings, no travel points that I can see.  I do like their bid room concept and also the $20 delivery option though.

Thoughts from the credit card savvy?  

Thanks all!
