You may want to research the term ' Debt Financed Distribution' Which does have a tax implication for the investors receiving a distribution.

Are there any strategies to sell subject to,s to end buyers?

It’s inconceivable to me how someone with a RE broker license, a CCIM, and a plethora of Series Securities Registrations can think that the property tax valuation would be reassessed at a LOWER value after knowing that the subject property and neighbor properties were being sold for record prices with each recent sale.

Whatever you do don’t put subject B on the title before A dies.
