Good option for getting money for further investing?

I think other options can get you places much faster. 

Call your banks and ask them if they offer any options and try to work with them.Another option is to sell one of your property, consolidate and move on...

The other two options require spending money that is basically going out the door to lots of fees and expenses of exiting your current house and getting into a new one.If you were just looking to move, that is perhaps a different story… If your house isn’t working for you, for instance.

To your question about the two different options, I think you could likely do both of your scenarios based on the capital amount you have. 

May be beneficial to join prop radar and refine search options to search this way.

The best option is to proceed with a cash-out refinance utilizing a DSCR loan. you can grab up to 75%LTV all by using the current tenant's lease agreements to cover the debt service requirement.

If you like single family investing, you will have a lot of solid options there.

Agree with Jacob that Facebook could be a great option.

A couple of options for you to consider: 1) Just let this first house-hack ride, and stack cash.
