Question for the STR finance gurus

[Collin Hays]

So I had the opportunity to buy a cabin near Gatlinburg in January at a great price.  I paid cash.  It produces about $36K a year.  Well I had an opportunity to buy yet another cabin nearby and I closed on it today, again with cash.

The only problem is, I'M BROKE NOW!  ;)  

I'd like to take out a mortgage on one of the properties and take a chunk of cash out.  But I have now 6 rental cabins.  Don't mortgage underwriters want you to have substantial cash reserves to fund expenses for all of your rentals?  Does anyone know what that number is?  What if I don't have it because I've written checks for two cabins in the last 4 months?  

Any suggestions?
