Hi @Steve Tse, I would recommend searching online (or through your HELOC lender) for a HELOC Amortization Calculator, and plugging in this information.

@Dhwani Shah Hopefully this is an off market deal because if it was listed it could be sold before we could even finish this discussion online. hahahaIf negotiation can lower the asking price (a little), rents have potential to rise, and deferred maintenance is low it's a home run deal.

I have been searching around for a little while and I cannot find any information or reference to online classes for an Idaho real estate license.
