They would be paying tax on interest they aren't actually collecting.I would strongly recommend you and the grandparents have a discussion with an accountant before doing anything.

@Michael GlotfeltyI would just say you are at the right place here at b/p to network with like minded people and all the education you can get here on this platform.

He really is a great guy and I don't fear the scam that many complain about but I feel strongly that whatever education they can provide (from $2-20k) can be found on BP and in other RE books for much less.  

I agree, HomeLine (https://homelinemn.org/speeches-trainings/landlord...) class for $50 was good educational investment.

By the lack of responses on here, maybe there aren't any good real estate lawyers near us

Secondly maybe you aren't in the right network and aren't speaking to the right people man.

Secured by the home itself, a HELOC offers a way to use the equity stored in the home at a lower interest rate than many other types of loans.HELOCs can be used for everything from home improvement projects to large purchases, educational expenses, or even debt consolidation/refinancing.

There really aren't brokers who do only multifamily in Chattanooga the volume is too low for that. 

This site has been invaluable to my real estate education, and I'd like to take it to the next level with networking here as we get our feet wet in investing. 

I believe these pricier homes receive less mail than lower valued homes, since high value aren't the 'typical' target of investors.
