I enjoy free money as much as the next guy I suppose. That's where owning rental properties has really paid off. It's virtually zero work as I use a property management company to handle the properties. So I just pay for everything up front. If I want more money I just buy another property. Haven't had a mortgage in years either. Anyone serious about money knows Credit Cards are for suckers.
I paid $7k for a surgery and was just gonna say, "Fuck it" and pay debit which was good enough for me but I sat there and said, "I'll get back to you in that." so, I went home and looked at which credit card had the best bonus, points or whatever they were offering if you spent $4k in fhe first 3 months which I would be able to get when swiping a card for $7k surgery. So, why would I use a debit card when I would have gotten shit back or used a credit card and gotten $2,400 back in travel points or $1,900+ in cash back which brought the surgery to $5k.

Credit cards can be used like a tool that can kill you or you can let it do the work for you and give you money back. I understand rental properties, investments,.. Etc but explain to me why I would wanna turn down free money for sliding a debit or credit card?

I had a few accounts through chase, citi,.. Etc where soke company's in Germany were hitting me with $17, $22, $12,..etc charges from a account I forgot about and stole like $4,000 from me and I had to sign affidavits to have the bank go back and get my money where as any credit card I uses alerts on my phone and its good for me.
