If you purchase an under construction 4 plex property and then the finished product is only 7 covered parking space instead of 8, can you get your earnest money back if you back out? 

What does that cover (not much).

Business needs to cash flow to cover existing and proposed debt by 1.2-1.3X.

If there are liens, back taxes, etc... the title company will identify what the issues are and these issues can be USUALLY be satisfied by the proceeds from the sale of the property if there is enough cash to cover everything.

Send a picture to prove it. 

When someone wants to see it, make them show a picture of themselves in front of the house, then a picture of their driver's license.

Greetings, I'm Sean Vitale and I found my way to BP through Mister Money Moustache on a search for financial freedom. 6 months ago I had no financial plans and I almost bought a single family home with no understanding of what that meant for my life or how it factored into the big picture. 

Who wants to see pictures?

Make sure you can document that and the unsolicited offer to buy completes the picture of someone who's intent was to hold but circumstances changed the intent.

My suspicion is that you are overpriced if your listing has quality pictures, marketing exposure on all of the “big” websites, and the overall condition is average or better.
