Perhaps it is the most ironic thing ever, but I get a sick feeling in my stomach and I react with "Oh no, they accepted my offer.  

Those first flakes would certainly have made my stomach turn into knots after putting that much into the landscape.

You just have to figure out what you are willing to stomach and then go get it done.

It's all about your stomach for risk. 

I can't stomach another 30 year mortgage.

Run worst case scenarios - then double the problem and see how your stomach feels when you look at the spreadsheet.  

Either you can stomach being a landlord or you can't. 

If you see a chance for appreciation in the area based on home prices over the last few years (or some insider information like a new hospital opening in the area) and you can stomach breaking even on the month to month for the shot at a higher price in 5 years this could work.Otherwise I would probably try and hold out- there is probably a sexier deal somewhere in town with similar benefits and a lower price tag.Good luck!

This will be very educational for him on how much "Stomach" he will need. 

If you go FHA 3.5%, lock up the remainder in where it will work for you with a level of risk you can stomach and some cash for emergencies.
