Of course, they also offer an unparalleled warranty on the notes they sell, so that is probably worth a premium.

For an exchange, they want your intent to be that you hold the property for long-term business or investment use (for both the property you sell and the property you buy).  

do you sell the duplex to pay off the mortgage or what do you do?

We might break even with selling the house even though we have also made some good updates to it. 

I have seen a lot of flips in my neighborhood and the surrounding communities, but some are taking a while to sell as many are priced significantly higher than the median home values on blocks that just aren't there yet.

Searching through past forums, some people say hold because it's the Bay Area (near Tesla and Facebook), while others recommend selling.

I’m thinking of selling the property7.

Why else would they sell so cheap?

I could sell the condo and "exchange" for something hopefully bigger but I'd love to hold and hang on to the San Diego property.

Not sure if I should sell and lose the awesome interest rate, or rent to get about $700/mo cash flow from this one property.
