Anyone with experience leasing executive homes - St Louis Area?

[Mackal Smith]

I have a number of small multi-family properties in South St. Louis City, but it looks like my former primary residence out in West County (Ballwin) is just not going to sell so I’m going to need to look at leasing it out. It was listed for 6 months last year starting at $500K and eventually came down to $450K then took it off the market for 2 months and did about a $25K rehab. It went back on the market April 1, but have still not had any offers. I’m getting things set up so that I can try and lease it starting July 1 in case I don’t get any interest before then.

My question however is this: My current income properties are managed by a property management company however this one (even at $3500/mo) will not cash flow so I’m looking at managing it myself however, how can I tell what market rent is for the property? Is there anything I should be thinking about leasing a high end property that doesn’t come in to play with a lower end property? I put it up in Postlets (now owned by Zillow) with an availability date of July to see what kind of interest I get. Should I also post it on Craigslist or should I be working with my current realtor to secure a lease? Is there a tenant screening service anyone would suggest for a higher end property? On my rentals in the city I always look for income at a minimum of 3X rents. Does the same work for high end property, or should I be looking at more/less?

Any suggestions welcome.
