Agent here also tried to sell me Derby... New build properties there for less than GBP 100k @ 6-7% gross yield... Seems like a "why not" thing, but then I look on the map and remember it's Derby.... (No disrespect to those from Derby or neighbouring towns). Can imagine it being pretty tough to sell at any time within next 10-15 years...
After sifting through the comments I've been put off Manchester... Helped by the fact that after doing a bit more research on RightMove/Zoopla, there are way too many properties available in the city centre, both to buy and to rent. Comparatively, some of the up-market towns further South such as St. Albans and Guildford, there is a lot less to rent or buy. But, of course the cost of both is much higher.
Should we pivot to EU countries?
