The whole house needs to be remodeled due to lots of wear and tear and being outdatedI am planning to use a HELOC on my current property for mostly all the repairs.

Sad to say, but i let this property go.

Purchase price: $130,000 Cash invested: $9,000 Sale price: $185,000 I did not have the knowledge then to keep the property and pull money out to complete renovations to another property we purchased a year after this one that required a complete overhaul.

I am assuming by your post that you are financially invested and own the property. 

Where is the property located.assuming the seller added the ADU and did not disclose the ADU in disclosure forms, you may have recourse (depending on the rules of your jurisdiction) but it may cost you some legal fees. 

I’d like to discuss it with a realtor, but I’m worried that if I disclose the deal, the realtor could bid against me on the property.

.: Its typical for real estate investors to hire a private home/building inspectors to inspect a real estate property before they buy it.

Next, we manually evaluate each property.

Purchase price: $160,000 Cash invested: $45,000 My parents my wife and I own the property next to this one.
