Hey Brett - Speaking specifically about closing costs, those can be a little hard to pin down.

If I were you and I see the specific rental market is on a decline, I would simply ask the tenants, so would you like to renew?

This is the first time I’ve heard from a legitimate company that is willing to work with my specific home warranty company.

I also want to fatten them up still slowly for now, so that I can cash out a specific amount of equity after paying taxes and transaction costs. 

I love this specific neighborhood in Louisville: the Portland neighborhood.

Are there websites specifically for travel nurses and corporate housing (finance, technology companies, etc)?

Ask specific questions, this is your property and you have a right to know what is going on.If he still does not respond, then I think you have to at least call an attorney and make sure that you are proceeding legally (for your state).I would bet @Nathan Gesner would have some ideas on this.....Good luck!

Happy to go through your specifics with you if you’d like

Just on the business level for landlords to be as specific as possible with their requirements and give detailed line item dispositions. 

Advertise that you are holding an open house on a specific date and time.
