Is there a value add component here, or is it being purchased below market value?

What are the key components to this letter that I must include to save myself legal issues and money as well as making it look professional?

Finally, there's a loyalty component.

If the latter, are you going to have an investment component of your primary residence?

It could be possible they would agree to add a HELOC component on top of the loan they are already planning to do.

Ownership is usually simpler with all those shared building components but in my experience not as profitable.

If you're eligible for a Solo 401k, you'll pick up quite a few benefits compared to the IRA LLC: Compared to an IRA, Solo 401k contributions limits are roughly ten times higher.There is no custodial requirement for the 401k.You don't need the additional expense and administration of an LLC to have checkbook control.There is a built in-Roth component whereas IRAs are either traditional or Roth, not both.A spouse can also participate in the same Solo 401k plan.The Solo 401k has additional tax benefits over an IRA when investing into real estate using leverage.The penalties for prohibited transactions are less severe, though it's best not to utilize this benefit :)

still hold these for incomeI am not going to argue with the bank and their valuation, if they value it at $200,000 there must be evidence of sales, as they are looking at recent sales comps including sq ft, land component etc.I am a simple person, I target markets that are rising, and look at value.

Assuming that this represents a significant portion of your net wealth then preservation and safety are the components you're looking for at this stage in your life and this stage in the market.Anything requiring appreciation is a non-starter. 

I completely agree with those key components you listed out about following up, negotiating, closing, etc.
