What is the best route for this 1031 Exchange Scenario?

[Laura Yazdi]

I have a condo in Los Angeles that I plan to do a 1031 Exchange within the next year. The property is worth approx. $450k and I will have $300k in cash once it is sold to purchase other investment properties. My ultimate goal is cash flow to be able to quit my job (self-employed) and focus on real estate full-time. Do I purchase a multi-family unit in Southern California for maximum appreciation? Or, should I purchase multiple units in other areas around the country and convert them to MTRs/STRs for maximum cash flow? Keep in mind, taxes and insurance costs in California are higher than a lot of areas. All ideas/ suggestions are welcome!
