There’s a lot of misinformation out there that is presented as knowledge.One can do a reverse exchange where one buys the new property first and then sells the original property after - all via a 1031 process. https://www.investopedia.com/terms/r/reverse-exchange.aspReverse exchanges do exist and they are “legal”. 

So many people try to convert a property they originally never considered as a pure investment property into an investment property.  

The fund, not being amortized returns more in the years following plus also having preserved my original capital.

Regardless, I'm just trying to give them the right guidance since there is a lot of equity in the property. back to my original post.. 

There will certainly be buyers interested in having an ADU but I'm not sure they will be able to pay for the cost the original owner incurred to get the ADU.

Depending on how far along this loan is in the amortization, there could be additional benefit in keeping the original mortgage in place because more of the PI payment is going to principle, opposed to if you were to take a new loan, where a majority of the PI payment will be going towards interest.As far as the negotiation goes, my method is to simply do run a few scenarios, making sure to add in whatever ROR or whatever metric you want to have as your investment criteria.
