I agree that you should request an extension for the contingency period due to insufficient information regarding the foundation.

Where would you take that money from if there were 'insufficient funds' in the "cashflow account?"

We are getting a lot of different info from different insurance agents on whether we need 1 or 2 policies.Obviously, we don't want to pay for two policies, but we don't want to risk being insufficiently covered.Appreciate and comments/feedback.

__is insufficient to sustain payments on the amount of credit requested.

==The electrical service to the house is insufficient/outdated and needs to be upgraded/replaced by a licensed electrician to 200 amps with each unit having 100 amp circuit breakers, including an owner’s panel for the common areas.

Or the rehab is going to be cosmetic in nature, insufficient actual improvements to be able to pull cash out anyways (spending $5k to paint a house does not increase value by $5k, etc).But, either way, it's a moot point.

I also have a very high limit credit card that can easily cover any kind of extreme scenarios if my repair fund was insufficient.

You have very little to worry about here unless you have a landlord-hating judge in your jurisdiction.You should give them a notice that the information they provided was insufficient to be categorized as and ESA and that they need to start paying pet rent.  

You might see a failing foundation, water intrusion, rotted joists, ancient water / waste lines and who knows how many other red flags.In the attic, I look for knob & tube wiring, missing or insufficient insulation, leaks, crumbling chimneys, etc.To have both of those areas off limits would be an absolute deal breaker for me - and shame on your Realtor, who is supposed to be your fiduciary! 

Whether one misses an opportunity because of insufficient funds or one misses an opportunity because of lack of qualifications (e.g., too high a debt-to-income ratio) is irrelevant; you missed an opportunity.
