Nice low guide Price for this property

I was on Rightmove this morning and saw two low guides, which are ideal for buy to lets. http://www.rightmove.co.uk/property-for-sale/property-45608319.html http://www.rightmove.co.uk/property-for-sale/property-45608322.html Both are for being auctioned and will sell on the day, they will be rented for around £650 per month, so depending on the price around £115,000 would be 6.8% however they might go for less then this even if you are lucky on the day. The lowest guide is £75,000 which is over 10%.
