Of course, this is not completely apples to apples as you committed the down payment, but you can discount the monthly savings going out several years and compare that to your down payment and it would be far greater.This comes with a caveat that had you waited and screened more properties, you may have gotten a better deal in which the math made more sense.

When you type the @ then the start of a name, does a list of choices pop up at the bottom of the screen?  

You must screen your property manager like you would any tenant, investment partner, or contractor.

Or maybe just let the lease run its course and not renew her, and use this as a learning experience and screen better in the future.

You can use it for marketing, and I believe they have tenant screening too, but I don't use those features as I have others I already use that I love.  

I make my places very nice to attract better tenants I also screen the heck out of my tenants.

Other than that, here are a couple options:Start advertising and screening potential tenants before the termination date of the lease and put together a short list and see if the start date for them will coincide with date the tenant is expected to leave (two months after lease end date).Find another rental for your current tenant for the two month period. 

How to prepare and pull the trigger for the "blood in the streets" Cycle?

I recently listed my townhome for rent and I am currently waiting on the results of the tenant screening for my potential renter.  

I've been reading about how to screen tenants, how to set up procedures and systems, etc. but the one area that I'm having problems getting a grasp on is the numbers side of investing.
