That's too rich for my blood!

If the money is invested in a deal with a long duration and cash flow timing such that you can't pay the investor back there is simply no good way to get blood from a turnip.

Heart rate and blood pressure just spiked.

Everything but your blood type will be asked for, the builder will need to have their house in order and be in good standing as well. 

for every one that went TU it took down 3 or 4 houses cash flow.. so when 10 or more went TU they could no longer pay the under lying and the sellers were out for blood they got turned into the AG..

I have done a number of remodeling/renovation jobs (i.e. master bedroom en-suite, bathroom and kitchen remodels, replaced siding and windows, etc.) on the houses that we have owned that have netted us well on resale value so I am familiar with sweat equity and grew up with a family that was involved in home building and land development so it is a bit in my blood there as well.  

The next time you go into a rehab (and there will be a next time, you've got to get your blood back!)

Red raises blood pressure & is identified with danger.

I want to leverage their equity to expand, but they put their blood sweat and tears into the build and they don't want to do anymore.

A lot of time, energy, blood, sweat and tears have been shed but we survived.
