Hi Marci!
I would suggest getting a list together of all improvements made to the property in the two years you've owned it (especially any CapEx, big ticket items such as a roof replacement, HVAC work, plumbing , electrical work, etc.) and determine how much the new owner could profit monthly/yearly if they were to purchase it after all expenses paid. If improvements/repairs are needed, you could gather details and their costs as well. I would then make sure all of this is noted in the listing for the property, wherever you plan to list it, whether that be on the MLS, Craigslist, one of the various Chicagoland Real Estate Investor Facebook groups (I can send some links if need be), etc. Maybe also share some details of the neighborhood, school district, what's close by, or anything that would attract good tenants. I realize you have one already in place, but good for investors to know for future reference in case she decides to not renew.
I also realize this post was from a little over two weeks ago, but I stumbled across it and wanted to share my thoughts. Also, if you haven't sold it yet, I'd be interested in hearing some more details on the property myself.
Looking forward to hearing from you either way!
