Yep glitter, that's another point I was thinking of.
The idea that the property must be sold and monies invested in something else quickly.
In fact, unless you know about buying and selling stocks, not just what to buy, which takes research, but setting stops so that you limit your losses, you can literally overnight lose a significant amount of what you invested, and it could take years, or maybe never, to recover.
Your property, even if some bubble "bursts" is not going to plummet to zero overnight.
Mostly, you would keep the property, continue to rent it and maintain it, and you'd then have the time to wait for any downturns to reverse.
I feel like I have a little advantage in talking about the values of homes here, since I've lived and owned in Austin about 25 years. Builders cannot keep up with the demand.
The inventory for housing is tight, and is bound to stay that way in the foreseeable future. employment is low, people will continue to want to move here. Unless this house is in some crack neighborhood, it will be easy enough to rent, and the owner will have relatively little stress if they are willing to pay a property manager. I believe it is well worth it. They screen applicants, take care of issues, maintain the place, keep records for taxes, and more. The owner would need to make sure they have enough to pay the property taxes, insurance, and other expenses. You have an asset that is not only appreciating in value, but earning income as well. That's like owning stock whose value is going up, and also pays monthly dividends.
To the OP, some questions...
Are you currently living in the house?
You have some vaguely stated desires about "wanting to invest". Invest in what? Are these investments you know anything about? As glitter said, beware of investing in friends business, or have someone talk you into the next big thing.
Your education....what are you looking to go to school for? What type of work do you want to do?
I don't get why you seem so all fire hot about selling a place when you have time to figure things out. It's not like you're going to wake up tomorrow and be the owner of something worthless. Over time, you're going to likely be the owner of something worth more.
Have you actually talked to anyone who is experienced in this sort of thing, or is this fear of losing something you were freely given come from some misunderstanding of long term economic trends? Long term as in 40 or 50 years, not 3 or 4.
