Where I would draw issue is a syndicator claiming properties in their portfolio when they are only a Limited Partner (specifically in marketing material).

That's the issue :(

In a perfect world, your primary would be paid off and the only HELOC on it would be for peronsal emergency issues - job loss, medical, etc.Recommend you find a lender that finances rentals, get a refinance going, then watch mortgage rates for the next dip to lock in a decent rate and close.

Too many potential issues with the younger crowd.

For the access issue into the backyard: can't you just add a gate or a door or both?

If I cashout refi one property , that would resolve my debt issues, but I'm torn.

We've had issues with Mario and his various business ventures. 

One of the tenants has been causing issues with other tenants.

You not taking action on this could potentially create issues in getting your property back.

We have only had one family rent it and they have just signed for another 2 yrs ( once that lease ends they will have lived there for 5 yrs will zero issues).
