Use tools like AirDNA or Mashvisor to provide market data on projected rental income and occupancy rates, and make sure your lender works with appraisers familiar with short-term rentals.

There are many markets that fit this description.

Name of the game for me is speed to move the contract.Currently I have a mass email marketing platform that works well but no one checks their email as much as their texts. 

What markets + strategies are you thinking of pursuing?

DSCR loans are based off of down payment, credit score and either actual or market rents so it helps to supercharge an investor's real estate goals and net worth.

I've tried stock market and never really made that much.

half of my clients in Miami are Foreign Nationals, in todays market ive seen 7-9% depending on some factors but im not a lender, just my experience as a real estate agent

The best way to do this is to renovate a unit or two to the specifications to bring it up to market.  

It's a good time to review markets, but living in China there are a lot of other closer, international markets that could be options as well.

I dont get much out of it as an investor except getting my son in a house vs staying in the rental market.
