Not really sure but this house is suppose to be 80-100 years old. It was bought by a 'flipper' who has had it renovated and now selling it. The house looks good but i notice some strange things, the bathroom has been renovated but they kept the old toilet and replaced everything including the seat. When i flushed i noticed it didn't flush that well, kind of a low pressure. Do you think this is a sign there is something wrong with plumbing? I'm guessing they planned to replace the toilet and found a problem? (of course the agent is mum's about any of these questions.) In the kitchen too was renovate but they only installed one sink, i looked underneath and notice the the instillation was bit unusual. I wonder if this another sign of problem? The electrical was replaced but i found some light switches to be not working. Do think these are serious red flags? I will get a house survey down but i was wonder what your opinion was? Could these thing be potentially expensive to repair?
