Far better than using a company already known for being a very bad option.I can certainly recommend very good agents.

I noticed that you mentioned using a HELOC on your primary residence to fund this purchase.

Have them set up on automatic payments or using a program where they can either deposit it at a bank, online, or another payment station. 

., Sub-Chapter-S Corp, IRA, LLC-Limited Liability Company, Individual, or Joint Venture Partner prior to COE- close of escrow" Is inevitably KICKED OUT or IF an attempt to ASSIGN the Buyers purchase agreement is requested - the Banks / REO lenders are saying the agreement and its time line will have to commenced from the START Anyone using a cool trick to deal with the restrictions to ASSIGNING a BANK OWNED property thru Escrow ?

That depends on if you are using a real estate agent who is investor friendly.

@Reggie MaggardIf it is a vacant unit then using a lockbox is fine.

Now if I roll that cash/check into another property using a 1031 exchange, am I going to be taxed on the heloc which will be paid off using the proceeds?

You buy a rental property for $100k using a 80% bank loan at 6% interest.

@Zach BeckerI recommend using a CPA especially if they will help with your tax strategy.

@Don Ireland , Using a separate account for house hack portion just helps with the bookkeeping.
