Is a 20% rent increase unexpected in a world where gas prices are up 50% and people are asking for a 100% increase in the minimum wage?

I try to have my lease agreements shift most of the responsibilities from my companies to the tenants, make sure my LLCs are sound and that my commercial insurance policies cover the "unexpected" events that could go wrong. 

Please, delight us all with accounts of your conquests.......

Ask what did they find that was unexpected and if any item was a budget buster.

They are just here in the unfortunate case where you die early unexpectedly.

Vice versa, if you are just starting out, you might want to be more conservative to tackle any unexpected expenses that arise.The 70% rule is an industry standard, but that doesn't mean you can't adjust it based on your desired ROI.

I'm thrilled to be joining your ranks and excited to receive your comments and suggestions via this delightful forum.

And notice how the common expression is one of delight when they hear a "yes", because it is more rare in start-up. 

Emergency Fund: Maintain a financial cushion or emergency fund to cover unexpected expenses or periods of low rental income.

Just remember you need to have enough not just per month but also for unexpected expenses.
