Since my owner financing offer involves such a large drop on deal price(made up for and exceeded through interest and time) does anyone use techniques to soften the initial shock of the offer?

Demands of stand/clap in formation/do a nonsense hand gesture are sales techniques. 

Image is important but you need to tailor it for your market.

We are all born under different circumstances and have different situations so we will use different techniques to start investing. 

As well, look into banks/credit unions that tailor to Veterans, these can be a great source of financing.Investment wise, house-hacking is still viable in Portland but you will have to have quite a bit of capital to make it work well.

Unless a customer directly asks about the upgrading of grounding and bonding techniques, I do not even bring it up, because quite frankly, it is an automatic part of every service upgrade and customers don’t really know or care about it.

I buy three of these houses per year using this technique.

Or, more likely, he invested in real estate and used techniques to devalue the asset(s) on his books while still holding the asset. 

An LOI is nice because it puts something in writing and since you're creating it, you can tailor that message instead of relying on the broker to relay your offer. 

I have 6 multi units in my pipeline this month alone, I close a lot of MF in all states, using cash instead of finance is not necessarily a good negotiation technique as seller wants to get the best offer regardless if is cash or financed, plus the 20%-25% down payment is already working on your side.
