While the idea of owning internationally is attractive, in reality it tends to be much harder to buy property in other countries (especially European countries).

Also, don't people tend to prefer Airbnb over hotels?

When you researched markets like Austin las Vegas Miami, those markets have higher land cost and are more cyclical in nature tend to have larger price swings compared to regions with lower land costs.

That said, I’ve found that properties in C-class neighborhoods tend to perform best with Section 8 tenants.

If the only MFH options you're finding are in areas you're not comfortable with, it might be worth focusing on a duplex in a better neighborhood.Saving up for a larger property later is a valid approach too, but keep in mind that real estate tends to appreciate over time, and waiting might make it harder to enter the market later.

These areas tend to attract more reliable, long-term tenants who are usually more financially stable and take better care of the property.

Now I agree the 4 will cash flow better than one will but I also look at it from risk of 4 properties will have higher maintenance costs and lower priced properties tend not to appreciate as well as a higher value assetI am also in it for long game and managing one is easier than 4

They tend to go out quickly and rarely look as good. 

You also tend to get more frequent and better feedback than with an STR, if you treat your residents well.The last quadrant, unnecessary but not obviously so, is usually as a result of either converting an STR to an MTR or from remodeling above the standard needed.

There are also a lot of agents who tend to get pocket listings or know before a property hits MLS.
