Just doing my usual daily browse around the portals and found this Semi up for sale with Claytons at £350k+
Semi-detached house with potential to extend - Watford
For full details check out it out on Rightmove HERE
You could convert the garage, go 2 stories on the side, extend the back and go into the roof.  So many options here!
Yes the house needs some tlc so you’d have to do that too.
Would it make a good investment?  I guess that depends on how well you do the work and whether you can keep the costs down. Spend £100k on this and you could rent it for £1800 as a 4 bed house.  That’s a yield of just under 4.8% which is good in Watford.
Worth considering if you are struggling to find those elusive smaller properties and you want to add a bit of value.
