Appears @Joe Villeneuve is testing your commitment with his advice to sell.

I have made an excel sheet with some data (thanks to BP Insights), and have crafted it so it spits out a nice number (almost like a grade on a test) when I type in a market.

I think its better to do it all at once so you retain it for the tests.

Over time, I've seem home inspectors point out mostly workmanship issues during their inspections of new homes and so I do feel it's worth the time and money for buyers to get one on new construction. our buyers will do the following.1. radon test   even though every new home needs a radon system to get CO2. they will run sewer scope..

@Arta Montero - I have been a structural engineer since 1996 (graduated WVU) and got my PE in 2000 when I had enough experience to sit for the test. 

What's the harm in doing a test run with the tenant & keeping your dad as a backup? 

Test different numbers.

I've been listing a few properties lately "as is" to test the market.

Maybe the perc test failed and they snuck it through.

Obviously these are extreme, but show what happens when builders don't do adequate soil testing.
