I'm from Tampa Florida and I have a few clients that leveraged their portfolio to buy new properties.  

It is much more difficult to sell an entire portfolio that has become uninsurable (which would require a cash only sale) or that insurance rates are so high that no one wants to buy. 

It normally doesn't cost you any money to open and to be able to access that large amount of equity to buy or stabalize your current portfolio allows you so much more opportunity costs.For instance, I took a $200K LOC out on my primary residence when I first started in real estate.

I currently work in the turnkey investment world helping investors create a real estate portfolio, if you are ever interested in trading different strategies and goals, I'd love to connect! 

Now if you are seasoned and portfolio is mature and you are not as concern about maximizing income then I can see a migration to SFH might suit someone.  

I dont know of anywhere that you can cashout $270k against equity in an RE portfolio without closing/origination costs other than through a private banking relationship as a HNW individual.

Good luck building your portfolio!

Excellent framework for growing our portfolios

What type of properties are you looking to add to your portfolio?

You can hear real-world examples of how others have built their investment portfolio and (hopefully) learn to avoid their mistakes.4.
