I wonder whether expert can confirm this?

One of our residents was robbed outside of this property and we ended up paying for the resident to move out and sold this property.

We used a HELOC on our primary to purchase and begin renovations on a duplex nearby, and just this month closed on a fourplex that has a couple units rented, and a couple that need full demo/flip (which is now in progress).I'm taking some big swings and really having a blast doing it.

If you want to stay in your house, then your only option would be to leverage equity which will probably be in the 8-10% interest rate range.Not knowing the entire situation, I think you could consider downsizing and then using the proceeds to buy a 2-4 unit property and start making $40-75K right away with still no debt. 

A duplex is a great way to start because that renter will help with your monthly out of pocket costs and it's a convenient way to get into real estate investing.

As your portfolio grows, then you can start looking into a property manager.
