.- Given the demand, buying on through MLS will be tough.

No surprise, this, along with job growth (HP is a large employer) forces prices to stay high as demand creeps up too.

HELOC should be used for repairs on the primary home or to buy cash flowing high demand area rental income real estate.

Re-read your contracts, document your correspondence (and attempts) with your builder and demand documentation to match up any payments/draws with what's actually been competed on your build.

Most reverse exchanges are done with cash from the client or a private loan of some sort from an individual or a portfolio bank.When your old property sells you will have that cash in your account to purchase the new property. 

And it would blow your mind the massive demand for there service.

There is just not much demand for cheap homes.

The goal is to expand my network with likeminded individuals in the same market.   

You need to pay attention to things like rental demand, upcoming developments, and overall area growth potential.
