Again, I used my parents but this time only as lenders of part of the money for the down payment.

Collect properties instead of money.

They have to prove to any relatives and "legally" interested parties, (court, relative, creditors, etc) that all money was collected and all debts were paid.  

Time is money—choose someone who can execute efficiently without disrupting your revenue.8.

Money was deposited into my account the day after checkout.

Each one with separate addresses and utilities.We originally put $585k of our own money into the project, and by the time we were ready to go to market in 2023 we were into it for about $2M (the pandemic really threw a wrench in our timeline and costs but also greatly increased the value).

There are a lot of websites that offer the course online, or if you have a college near you, they also typically offer a class that satisfies the pre-licensing requirement.

When you borrow money you agree to pay it back.

If so you should be able to cancel but if you are doing it out of the inspection period you are stuck and could run the risk of losing your earnest money if you put any down. 

Are you using your own money for your flips or do you have a lender/investor that funds your flips?
