BTL. Are 3/4 beds better than 2?

[Phooey]

Tidy, low maintenance modern 2 bed houses (not flats/apartments) in my area are approx £145-150k and let (easily) for around £500-£580pcm. 2 beds seem in short supply and therefore sell/rent quickly..

3 beds seem to let at around 675-700 (so 20%+ on a 2 bed) and sell for £160-£190k.

Has anyone else done the maths and thought 2 beds are relatively expensive (due to supply and demand) and think 3 (or possibly 4) beds might be a better long-term investment?

Cheers

Thanks for replies

That is my thinking nct001 - the newer the better - it's not my day job so need to minimise the work. I should of done it 10 years ago when i looked into it.... need to start researching, again
