My HELOC requires monthly payments and I would not want it to be dependent on a rental, anything can happen.Yes, the interest is deductible from what I discussed with my CPA when using it for investments and not personal use like paying medical bills. 

They are NOT a part of the Rental Agreement and are specifically exempt from it.

. - Owner filed for tax exemption and for that exemption has to make LESS than $40K a year- Owner removed a homeowner from mortgage in 2009-Owner bought the house just under $700K in 1997-Owner recently made a payment lowering his balance but he still owes My question is how can we intervene before the home goes to auction?

@Michael Workman maybe they claimed a homestead exemption?

One side is rented to a family that had bad credit (medical bills), no rental history (lived with parents), but have been there since May and have been great!

Looking at purchasing a property, shows that it has a 17,000 medical lien on it, property is not getting any bids, going on its 6th time up for auction, confident i can get it for the reserve of 37,000, the bank is owed 164,000, does that lien attach to me if i buy this property or does it get wiped since the bank is priority and they wont even break even?

They have programs that offer ESL (English as a Second Language) classes, medical services, and after school programs for the kids. 

@Aman A. this will qualify under the delayed financing exemption but it will still be considered a cash out refinance. 

You have nothing to worry about in a 3 unit building- it is exempted.
