The answer is, “It depends…”
How old are you? Where do you live? What kind of financial assets do you have?
In the United States a person who is 18 years of age or older or an “emancipated minor” can do as they please without parental approval. If this is you, learn as much as you can about investing in real estate and start to invest slowly. If you aren’t of legal age yet just hang in there, you will be soon enough.
When I bought my first home my parents believed that people only bought a home after they got married and to raise a family in. They didn’t understand the tax benefits and appreciation potential that properties offered to a single person because they owned their home free-and-clear and lived in an area of very low appreciation. They thought I was going to be arrested for tax fraud at any moment no matter how often I showed them the IRS regulations.
It wasn’t until a decade later that they could see how I benefitted from owning real estate and even eventually co-invested with me on some rental property. Confucius used to say that, “When the student is ready, the teacher will appear”.
Don’t force your opinions on your parents just as you would not want them to try to think like they do. Good luck!
