Do you also provide a Welcome Basket with a list of Emergency Numbers and Other Local Information?

If none of the windows are openable, then it could be a higher liability in the long run due to lack of egress in an emergency situation, but ultimately that's an attorney/insurance provider question.

Be stuck with no emergency fund is no fun.

A few things are: fire separation distances (window/door opening location/sizes in relation to the property lines), easements (hopefully none of these garages were built on city easements), egress (adequate emergency escapes from bedrooms), utilities (are they separate meters and were they installed up to code?) 

I'm far from an expert in real estate but my observation is that the real estate industry is being disrupted and new business models are emerging.

Phone the non-emergency number for the police and ask them what to do.

You have a $22k head start minus a 6 month emergency savings.

I think the best way you get there is growing your company by reinvesting your available cash flow, I'd only withdraw money from your business if you absolutely needed it and it was an emergency.
