I'm looking for some advice on how many analytical scenarios I should consider and which scenarios should hold the most weight. 

@Steve Vaughan  lots of factors for the commercial banks.. regulators might have told them to reduce exposure to real estate.. so there goes your refi.. bank could have failed.. ( this happened big time) in GA 450 small banks failed in the GFC big player buys all the loans for pennies on the dollar and you are not getting any love from them pay them off or they foreclose.. saw that more than once.. regardless of what the asset was or was doing.but lets remember 08 to 2010 hopefully was a once in an investor life time situation... but it can happen. your smart to limit your exposure to those types of loans..

If they don't want to sell at the price the only thing you can do is sue for specific performance....and lawsuits for specific performance fail over 99% of the time.

When you budget for property management, you need to actually know what property management will cost.Property management is worth its weight in gold if you find the right company/manager.

If you fail to do so and tenant contests it, landlords can face not only returning the full deposit (no matter what condition it is in) and paying any legal costs associated with it.

Exception would be if you're doing a high end flip, where a well designed and thought thru space would carry more weight.

If the law firm went out of business and/or lost the deed (or as happened one time, a paralegal mistakenly shredded a deed that had not yet been recorded) and the sellers failed to or refused to or couldn't cooperate when the CFD was paid in full, I'm quite confident the cost of cleaning up the mess in the courts (at least in today's dollars) would highly likely in my state be $3000 or less (yes, there are circumstances when this number could be higher but they are highly unlikely and still would almost certainly allow the deal to be profitable).  

Only rent guarantee that would mean anything would be in a lease to the government and that can change as well, don't put weight on the guarantee part but you may have a great tenant.You have to take risks in business, if you can't sleep, your risk tolerance is too low. 

They are buying an investment.In my book, local investors fail because they're doing it wrong.

And if the fridge fails, you've got to get a new one in there ASAP!
