Conventional loan while utilizing your HELOC for the down payment would be the cheapest option across the board. 

The same company is now charging $850.

They charged to come back and fix, and one still isn't working. 

Add 1-2% to what banks charge for interest .

Also I realize this is a huge jump to make for a first time investor on a property valued so high, but I figured the terms were amazing and I am having a difficult time getting approved for conventional loans to start smaller.

Alternatively you could mail it to them and pay the small charge to have a confirmation number that they have received it return to you.

It's only a state convention), and purchase in your name only then you are not changing the tax payer because all activity of the property would still be reported on your personal tax return.So that's a qualified yes from me.

It may sound nice to pay a 5% management fee but the extra fees can add up to be more than the other company that charges 10% with no add-on fees.

Ask him what he is charging for the job.

A good commercial attorney may charge a couple thousand dollars to create a contract.
