Sell by owner -Student Rental

So my house is a bit different.

I was hoping to get it on the market myself just to test the waters. If there was strong demand I could sell it myself but if there was no interest I could get an agent involved later.

What sort of strategy would you guys suggest? I am not after the normal home buyer, not even the normal investor. This lends itself to a more hands on type who can self manage for higher returns.

It is a multi bedroom place by the university with about double the rental income of a similar house rented to a regular family.

Are there websites that I can use?

I was thinking Gumtree or even eBay to reach a broad range of buyers. Any experience with those?

Thanks
