I own a duplex and am selling it.

We bought for $379,000 3 years ago and I could sell it today if we wanted for $475,000.

Forcing the seller to sell because they initially agreed can be a recipe for disaster later.

Quote from @Luis Pereiro: Quote from @Jay Hinrichs: what position that's an important factor.. bare land notes generally sell for a 20 to 30% yield. 

I guess we could maybe have the builder agree to the cost of the build and if we sell for more or less then the profits would go up and down based upon the selling price.

Periodically checking the realtor.com and zillow "sold" listings in your areas of interest will keep you generally informed on what properties are actually selling for.Feel free to reach out with any questions during your research phase, happy to share some additional stats/info.

So many people get anxious and want to sell their property, even if it's performing good.

Maybe one day I can sell this system, but right now is for my use and under testing.

The one caveat being that when it comes time to sell or refinance one of the properties there may be a partial release clause, causing you to pay the bank back more (120%) than the original loan on that particular property.Happy to be a resource!  

It also is helpful to have a California LLC in case you ever sell that property and move into another state so that you do not need to form a new LLC altogether with new operating agreement, just re-register in the new state as a new foreign LLC.
