I think you should hire a professional to inspect the house so that you will know whether these problems can be easily fixed or fixed at all and whether there are other major problems with the house. I don't think long distance advice will be very helpful.

In northern Virginia where I live, house sales contracts typically provide for a housing inspection to determine whether the house meets building code and other legal requirements. When they do not, buyers can demand that the problems be fixed and can back out of the contract if sellers refuse to fix them. There are lots of inspectors who buyers can hire for these inspection. Typically, inspectors have been contractors or have worked in the building trades or in a government code enforcement office.

If you don't have inspectors where you are, find someone who repairs or renovates older houses and ask him or her to perform an inspection and give you a report with ball park figures on repairs or renovations that are needed. An inspection by a professional will be money well spent.
