And as we saw 2 1/2 months ago, the bottom can fall out of the market very quickly and unexpectedly.

The tenant just called and said she is now going to move out on May 15th and wants me to pay her $500 worth of moving expenses that she is “all of a sudden and unexpectedly incurring during a pandemic”.

Unexpected/hidden utility costs can kill the value of a multi pretty quickly. 

But make sure you make room for unexpected costs. 3) I didn't shop around for some mortgage costs that are allowed to be shopped, and you should.

February 2019 at the age of 62 I accidently came across a screaming deal.

Rather than putting an unexpected bill on a credit card you should have your 3-6 months of savings to use.  

Unfortunately, 4 years ago we were hit by unexpected sickness that took a great toll on our credit.

In my opinion it’s much better to pay a few hundred bucks to know for certain than buy the property and have potentially thousands of dollars in unexpected costs down the line.

But I'm a 30+ year pilot and I read the accident reports--pilots always say "I'd never take off in that kind of weather" or "I'd never let myself get that low on fuel, I'd just make a fuel stop", yet the leading causes of general aviation accidents relate to flying in adverse weather and fuel mismanagement. 

I would like to do a cash out refinance for $1.2 million ($600k cash back) for purposes of some completing some common area renovations that are larger than we can complete by dipping into monthly cashflow, renovating our only vacant space, and cleaning up a tax debt (feds, not property tax) that unfortunately built up due to large unexpected repairs having to come out of cashflow.I would also like to obtain a $100k commercial equity line of credit for normalizing our cash flow when these larger unexpected repairs come up in the future (emergency AC unit replacements, boiler repairs, expensive elevator repairs, etc).
