If its not one of the 3 emergency's, forget about it. 

Also look for emerging markets or areas that are seeming to grow.

ETF doesn't offer much advantage over mutual fund for retirement account in my opinion, as you don't want to trade often or cash out (unless for emergency).In general it's recommended to contribute 10-15% of income to retirement account.

Unfortunately i have a family emergency so i am not unable to attend.

Most repair calls with STRs are "emergencies". 

Let them know about the incoming storm, share local emergency resources, and offer flexibility if they want to reschedule or cancel.

Real estate companies that embrace this new reality will emerge not only compliant but more resilient, more attractive to investors, and better prepared to navigate the future of the industry.

This mindset encourages thorough research, allowing investors to identify emerging markets and trends that can lead to lucrative opportunities.
