I think you’ve been watching too much HGTV! (I love those shows, too!) But it’s not as easy as it looks to flip! Especially now, with interest rates rising. This is a BAD IDEA!
Concentrate on earning enough from your job to pay your own mortgage and take care of property taxes and any issues with your own home. When you have “extra” money open an IRA at a bank or at Fidelity and let your money grow tax-deferred. Keep contributing to your 40l(k) at work. In the long run, you’ll be glad you did.
