Carry a set amount of cash on you. This way, you know when you've reached your limit.
Leave the debit and s at home and you'll be forced to think about what you can afford any time you make a purchase.

When you need a loan to finance your real estate buying or selling, try to work with a portfolio lender.
A portfolio lender is one that will retain ownership of your loan rather than resell it to third parties.

Keep good records of your expenses. If you aren't keeping accurate records, it's doubtful that you are claiming all you are allowed at tax time.
It also makes your situation very difficult if an audit should happen.
