The asking price of £500,000 seems somewhat high given the size (642 sq ft) and the lack of detailed information on plot size, which might be significantly lower than surrounding properties. Comparing to similar properties on Boundary Road and nearby streets shows that the price is at the higher end of the range, making it less of a bargain, therefore the score is 6.

Based on the provided photos, the property appears to be in generally good condition. The interior is presented well, though some areas (such as the kitchen) appear dated. While there are no apparent major repairs needed, the property may benefit from some modernisation updates. This reflects in the 7 score.

The property benefits from its proximity to St Albans city centre and mainline railway station, providing convenient access to London St Pancras. The area also boasts several well-regarded schools within walking distance. However, the specific location on Boundary Road may not be as central or desirable as some other areas in St Albans, hence the score isn’t a 10.

The property includes a small to medium sized garden. While not extensive, it offers some outdoor space which is a common feature and desirable in this type of property. Considering the size of the property and its location, the garden size could be considered average or slightly below average. This rationale supports the score of 4.
