I am interested to hear what others think, their methods to finance, tools they use and if they would go for it.I might be able to bring some other financing from family but we currently have about 140k to put down (yes I know that's low). 

I have even bought properties with this CC method and sold them wholesale a week later.

What methods did you use to acquire them? 

You’re either conflating a different payment method than credit/debit(like giving direct non third party ACH access to your tenant to your account) or talking about a fraudulent situation with a judgement or you or your “someone” is being less than honest.

For Buy and Hold strategies, this method is far more superior than traditional financing of properties.

Find Brandon's videos on YouTube for the "four square" method of analyzing homes and practice.

This is a popular method to execute the BRRRR strategy.

Personally, I've never bought this way, but I have sold using this method.

If there isn't one website or source, what is another method other than looking at the competitors?

But if you have a little money to invest, then skip-tracing and contacting property owners is another method.
