I predominately work with out of state investors looking for cash flowing rental property in our market.

The current market value of the NC property is around $260k, with an outstanding mortgage of about $160k, resulting in approximately $100k in equity.My current residence in Beaufort, SC is a 4-bed, 3-bath house with a higher interest rate of 6.5%.

Those sales may happen off market between you two, or may have creative terms, but really you're negotiating two separate sale both of which only happen if you both like the terms.
