I purchased a two-family property in 2017 and now have around $500K in positive equity.

I'm looking into a 1st Position Heloc for my rental property in CT.

@Zara MassoudAdding your property manager as "additional insured" is standard practice and beneficial for you.

Did you ever find a solution for a 3rd position heloc?

@Vijay Radhakrishnan Thank you so much for the positive feedback. 

The landlord should be named on the tenant's insurance policy for additional protection and to assist with tracking compliance.

Additionally, I would like to attempt to do the process Owner/Builder with subcontracting work out as well as doing some of the work I'm comfortable with (I have some experience with bathroom & kitchen remodeling an am not new to the construction industry).

I am considering building up on my fourplex. 2 additional units.

The most reliable method to locate liens and their positions is to conduct a title search through a title company.

If you sell a property, and do a 1031 exchange with the proceeds, but don't need all the proceeds for the down payment of the next property, are you taxed on the additional profit that isn't part of the exchange?
