I’ve saved enough for a down payment, but I’ll be left with only a little bit for emergency funds.

I'd be very surprised if they would consider a less than total deal, unless they're really desperate.

At over 4000 sq ft, I'm surprised you won't be able to list for a much higher number to net a decent profit, but without knowing more specifics on the house and location, I am speculating here. 

I'm surprised by some of the responses here about how people like VRBO more than AirBNB.

As another poster mentioned rates are lower than they've been in the previous 18+ months but unless some very surprising economic data comes out between now and when you did your refi it seems unlikely that rates are going up in the short term and there is at least a decent chance that rates drop a little more before then. 

Although the list may seem intensive, I look at it like this: The total cost of all these items can be much lower than the cost to repair a hidden surprise after purchasing a property to flip. 

They rejected my offer; I was neither surprised, hurt or insulted by the rejection. 

My wife and I bring our own pods to every STR, surprisingly only about 30% have Keurig and it always bums us out.

This is not surprising.

EDUCATE YOURSELF - yes, it will take time, but will lead to a selection that better meets your expectations & avoids potentially costly surprises!
