Advertising, credit checks, screening etc.It's just business and once they are gone you can cross them off your friends list.

My original RE Agent, Bill Davidson, found me my duplexes from the MLS by noticing that they were all mis-advertised.

The DIG REIA where @Percy N. and I are members has some newsletter advertisers that sell appliances - Gerhard's and Queen Appliance.

What you could do, and what I have done in the past, is advertise the property as coming soon.

I've been calling for rent advertisements to try to get my feet wet in asking whether or not they would like to purchase more or sell any units but I like your idea better.

I've been advertising the property online for the past week and already had a few families put in rental applications for $1100 monthly rent.

Would it be smart to advertise for 800 and risk taking longer to get a tenant?

If it's the later,, more than likely your over market price or not offering suitable terms.Get out look and at the competition and get a perspective of your price setting.Usually a rental is advertised well in advance of the present tenant vacating and your in the wrong end of the loop people looking for rentals now are planning on vacating December 1st,, people usually look 60 days in advance to get perspective if they are going to give notice where they are to relocate in 2 months.

@Presh DineshkumarMost of the Plus and Pro membership "perks" are very U.S.A. focussed - even the on-line calculators - and have less practical value to Canadians ... even those unfortunate enough to be stuck in the GTA ;-)Some Plus/Pro features .. such as the search members by zip or postal code now work (sort of) for Canadians (polite nagging can pay off ).If you are a flipper, or offer a real estate related service (architect, trade, etc), then the ability to post advertisements to the Real Estate Marketplace is a benefit.I upgraded to a Pro membership early on to support the site and its growth as I found it to be a credible venue for exchanging knowledge and making contacts with respect to real estate. 

I remember someone from a podcast used preliminary advertising to test the demand for rentals.
