I noticed this 2 bedroom apartment in Sharps Court which is minutes walking distance from Hitchin’s mainline train station. Details say only available for investment purchasers as a tenant is already there, reducing any void period for a purchaser.
On the market for £230,000 it looks well-presented and has a ready tenant in situ.
This type of property would probably rent in the region of £900-£950 per calendar month, which in turn would generate you an annual gross yield of 4.7%-4.9%
