The note investor who thought interest is paid on the original principal rather than the unpaid principal balance.  

I can’t say I disagree with the analysis, just think (I’m sure this will sound incredibly stupid in the future) ultimately bonds and mortgages are likely to trade in a very narrow band the next few months, without a really nasty recession I find it hard to see them getting much below the 3.75% they hit Monday, I also think the Fed wants to keep the number below 4.25% because while I don’t think the economy is in a recession or anything it’s clear to me and I think the Fed as well l, that the economy probably can’t handle another year of rates above that, they will lower rates & possibly even taper qt to achieve that outcome.

The new property has to perform enough better than what you have to pay the higher interest rate on the higher balance, AND ADDITIONAL profit just to payback the $65k you lost selling.

You can test that side of it out to see if it's a good fit for you, but take some time to find which side is the right fit for you because that will be a key to achieving long-term success.Also build as many sponsor relationships as you can in the beginning because that'll give you plenty of options when you find a deal. 

Maybe offer to pay a portion of the balance contingent on completing the work or signing a waiver to avoid the lien.

@Tom Stevensonyes, when I BRRRR I typically use my own cash for the down payment, and a hard money loan for the balance. 

If the amount paid to purchase an existing note is below the principal balance or more correctly, the unpaid balance, the investor will benefit from an early payoff to the tune of the discount.  

Where I would ultimately like to end up is with multiple properties that I rent out, even on an international level, as I love to travel.In order to achieve my goal: What strategies could you all recommend?
