Is this a affordable lifestyle goal?is it possible?

Anything is possible. It's also good to dream big.
You'll need the kind of income that usually comes with a master's degree. Or you need to learn how to save and make your money work for you.

Your goals are reasonable. A 400k house will run you about $3000 a month, then you need to pay for lights and everything else. Let's say you pay for 2 of the cars cash and have a car payment on the porshe of $400. Factoring other basics like food, your minimum need would be $4000 per month- take home. Remember taxes come out of every check. So you're looking at somewhere around $55-$60k a year to just scrape by.
