Cons: they are nearly exclusively variable rate, some lenders called them due in down turns.   

We timed the market well also - I could see commercial prices still undervalued - and we picked this up at a 20% discount on today's prices - so over $200k in very quick equity gain.

I manage exclusively STR's for residential real estate and some STR's mixed into my commercial property.

Anyone who came back to me with those issues looking for a big discount I would probably dismiss as not a serious buyer, looking just to low-ball and get it under contract so they could then try to get big money off the price later. 

Or would my realtor be almost exclusively dealing with me?

I wouldn't offer any discounts or to cover any other moving costs.

At what volume should a discount be discussed?

The more modern view among experts, because of some statute changes and other reasons, is that if you are in exclusive possession at the time of the tax deed, you can quiet title immediately.

Just something to think about other than having to sell the notes to investors at a discount.

Bought stocks at a discount.
