I'd agree with Brian..to a point
It's a buyer's market now and the Agents and some of the sellers know it.
Both these properties are a good example of having a little bit of money spent on them so the prices can be over inflated
The first property has cleaned and had a 'lick' of paint,any real problems with the property probably haven't been fixed so not really worth 19,000. It's worth 10-12,000 at most.
Again,the second property hasn't really had a full re-furb,just a bit more work and cleaning than the first.The old windows have had some fresh varnish,some cheap tiles and laminate,not worth more than 25,000.I'm sure both these properties look more attractive as photographs
If you have money to spend, don't rush! there's plenty here for sale. I would put some of the money aside for a few visits here before you even consider buying. And do a few months of research, make sure you know the FULL process of buying and all the pitfalls,plenty of questions can be answered on MYBG.
As far as leaving your home empty, it's the same here as anywhere else. An empty house will always be a target, that's why you should always research the area before you buy. If you do buy, use the services of SOT to secure your home http://sot.bg/index.php?see=home&lang=en
