Could the layout work for you
Imagine the place with no furniture ( you may use a bedroom as an office for example ) and your decor choices
What state is it in? Do the windows /flooring /woodwork/kitchen etc look in good nick -things that could be expensive .
Have they been papering over cracks
It doesn't need to be pristine , just well maintained
Signs of damp inside or out .. look at the ceilings. Changes of shade on paint
Can you see damage anywhere , especially brickwork or roof
Acoustics..can you hear your partner when walking in a different room . What do the stairs sound like
Where is it ? Have you been down the street at different times of day/night ? Rush hour and 10pm are good choices. Walk not drive, how does it tell ? Safe? Noisy? Busy ?
Take a tape measure if room sizes look tight , sometimes things just work anyway
Then you can work out what it's worth to you
