I think there's a place for a legit tenant advert site, but it may be hard to get started.  

But to get started the above advice from other posters is the best way to start.What people may have meant about BP is that you could post an "advert" in the marketplace. https://www.biggerpockets.com/forums/517-real-esta...I think you have to be a paid, (pro), member to do that but that is probably what they meant.

I might have had one or two tha thad jobs but despite advertizing "No Smokers," this was ignored and both claimed that they would smoke outside.

Eg instead of advertizing it for $1500, advertize it for $1600 and say rent includes snow removal and mowing. 

In 30 years I NEVER advertized my work, never had to, it was all word of mouth.

What happens if I see the property and realize that the repair costs are more than advertized and the deal doesn't make sense and I want out.

@Chris Martin - I came across the idea of “accelerated banking” and "first position heloc" from some lame YouTube advert. 

That said, I use a professional PM, so instead of advert date, I use our property management contract date for my in-service date, with the contract as proof should I ever face an audit. 

We saw an advert for decent priced homes by a developer for sale in the Poconos and decided to take a road-trip to inquire.

We've found that some yield no interest in our area, for example we're dropping Furnished Finder for our next advert round.Best wishes to you and again, we highly recommend Al Williamson's course--it got us to our destination faster, with more confidence and with a community of peers and it was, in our view, it was well-worth the cost.
