Come even the slightest ripple (an increase in property insurance, an unexpected repair, etc.) and suddenly you're drowning in a sea of negative cash flow.Also, are you including both professional property management and vacancy in your operating expenses?

When issues come up, and eventually they will, such as vacancies or unexpected maintenance issues, this is where we've earned our reputation.  

I did this once, kind of by accident LOL.  

Additionally, covering unexpected repairs and meeting lender requirements can pose obstacles, especially for newer investors. 

There are often unexpected expenses, and you want to make sure you have enough cushion to get through those surprises.Given the current low inventory environment, I would say securing a good deal is challenging (though not impossible) in general.

Don't underestimate the delay in a flip project. some accidents and events (e.g.

A bad area on the other side of town that unexpectedly moved into my neighborhood after federal law enforcement decided it was time for a crack down on gangs, who just relocated to my hood.A bullet through my bedroom window.A drive-by shooting 1 block over that I only woke up to at 4am after hearing a woman screaming outside her house.A friend managing similar properties across town clubbed on the head as he stopped by to collect rent, waking up hours later in the stairwell, pockets emptied. 

(Sorry accident hit post before I finished the sentence)

When you prioritize your guests and pay it forward, you’ll often be rewarded in unexpected ways.
