Or keep building and retire your self sooner.  

The last one we paid cash for and self-funded the improvements too.

Primarily self limiting beliefs.One of my clients just closed on their first commercial deal and they only had one duplex before I started working with them.

What would push the needle for you as a broker to confidently move forward with a buyer in the process of acquiring a building?

If an issue is professionally fixed where the buyer feels confident it was addressed COMPLETELY and CORRECTLY, then I think you don't need to worry so much about resale value.

You're in the business of flipping houses, so any self-employment taxes on the ordinary income most likely aren't being calculated in QB. 

I think if the industry as a whole was a little more honest with it self and with market participants you might not have as many waiting for something that is not likely to happen in the short term. if you need a house, you need a house. but, if you think something will change in 6 months you might be able to hold on, but if it likely will not change in the near term you might just bite the bullet and buy.
