It's a strategy allowing you to defer capital gains tax when you sell a property and reinvest the proceeds into another 'like-kind' property.

So if their estate is subject to estate taxes, the heirs may be forced to sell the property just to pay the taxes (assuming they made no other plans). 

All of the meetings that I see about ADUs are sponsored by builders who want to sell their ADUs.Are there others who want to build their own or want to share their experiences about building ADUs / converting outbuilding / navigating codes in Portland that DO NOT involve hiring one of these tiny house start-up companies?

Any big things that stand out quickly identifiable for when a home would be a bad candidate for a pop top rehab?

Should I sell it or build luxury homes then sell?  

Currently, I have $300K in cash that I want to use and buy a rental (SFR) property  selling for $250K.

Negotiated a private loan with 3% interest for 20-years with a $90k selling price.

For example: Right now an investor whose commercial multi family qualified at 4 % in 2019 maybe cannot make the grade at 8% today so that investor would need to pay the loan down with cash to qualify or sell.

A possible alternative to cash out is to sell the property to your family member, so that the property stays in the family and the equity is accessed.
