I've used to it myself to analyze all of the 35 units I bought over the last few years and personally talked to 100's of other investors who've analyzed and closed on great deals using it.I'd love for you to actually try it and would be happy to receive and incorporate any feedback you have into future releases.

While I don’t yet have personal experience with a HELOC, I’ve thought about this one for my self many times.

Yes, I'm a Property Manager in the greater Phoenix area.We are a mid-size property manager, large enough to have great tools and support but small enough to provide personal service.

I agree with the person who said they are likely short of money and grasping at straws.

@Michael Plaks comments in this recent post on making sure the person you hire understands real estate sounds really relevant to your situation.  

In the event that there is an emergency, the person would need to be able to exit the apartment via the window.

depending on where you are in NJ you might have the Lehigh Valley in PA a couple hours away, or Delaware, etc. you can go to meetups, see places in person, and start to build a network.

There are quite a few solutions out there so that even the most tech challenged person can pay electronically.

Either way if you personally guaranteed the note, yes it will affect your personal credit no matter who the property is titled to.
