I know next to nothing about the market for notes, but at a 15% discount rate (which I have a feeling is very generous), your $42k note has a present value of around $17k, taking into account that for the first five years you'll have to pay the hard money off.If I were in your shoes, I'd sell everything on the open market and move on.

If you come to terms, they can often refer you to someone in their office who can act as your agent at a discounted commission since they didn't have to market to find you or do the work of finding the property, they just have to get you to closing.

I gave private, discounted, first dibs to the two people who are directly responsible in getting me started in real estate.

Only a few are offered at a discount to market price.

Lenders trust the ones they work with and discount the points so you never pay more.

(From your comment, it sounds that you manage the houses)  Another factor to consider is that you actually get a discount on your property insurance when you use a licensed property management company.

I've looked at them since for appliance sets for my rentals but always found much cheaper locally - Appliance Direct scratch and dents (negotiated down) and Lowe's using discount gift cards and coupons with sales.

Always buy at a discount in expensive markets.

In my view, getting only a 10% discount to market value is not a good deal.

Anything you can pick up at a deep discount to wholesale will generally have a lot of problems.
