Thorpe Road with 4.6% return and a tenant from day 1

This large three bed end terrace property is on for sale with Moores Estate Agents for £155,000. The current tenant is paying £595 pcm and I believe would like to stay in the property. It let really quickly and has undergone considerable investment since the current owner purchased it. 
Although it is on a busy road it has a lot of character and an enclosed private garden at the back.
