Y'all gotta take this advice with a grain of salt. The getting a job and building your credit is right but the real important part is KNOWING what your boutta do with the 100k before its in your hands (aka you gotta have business model ready). Don't forget you gotta pay that money back to the bank with interest or else your gonna end up in a worse situation than when you started. (Bank seizing your home, your car, etc.)
If you have 780-800 credit score and already have a business plan before you "Crash out your credit", you just go to the bank with your business plan and still get the $100K or more and still have your credit and pay monthly against the loan and run your business. IJS
What he don't tell you is that there's no reason to "blow your credit out" - and if you do, you can't own anything in your name...because they will put a lien on that sh*t or take it. You can just as easily build your credit up and get a business loan, mortgage, etc. Have fun putting everything you own in someone else's name...and having them control your life. lol
Predatory Lending will not let this happen. Debt to income ratios will be off. Most banks willing to lend will be hard money lenders at very high-interest rates. At that point, you working for the man. All your profits will be used to pay back the lender and interest rates.
