Rather than chasing dead ends, follow the advice of earlier posters and have the property inspected to your satisfaction. And if you're not satisfied, walk away and find a property in more satisfactory condition.
All the best,
The home inspection process is a non~invasive, visual inspection. If still in doubt about the condition, get professionals out there to give their professional opinion. If still in doubt, then walk away. That's what the option period is for. Better to spend a few hundred and walk away, then not inspect enough and buy the money pit.
Have a blessed day.
The previous owner might not even know. That's not unusual.
This is tough.....Invoices from a general contractor might help.
Information from your inspector is another resource, but they can't always tell what was done, just if it works or not.
Other resources might be neighbors or the inspection department in your city if permits were pulled.
You won't know the extent or the quality of the work.
Sellers are only required to DISCOLSE what they KNOW about the repairs.
If they were absentee landlords, they may not know much and you couldn't hold them liable.
This is a real Caviat Emptor; you've got to do your investigations!
You need a good team of INSPECTORS, to know what you are inheriting.
General, Pest and Roof, at the minimum.
Good luck and may God bless
Don't waste too much time worrying about what was done or not done by the previous owner. Consider viewing the home with someone that can view the property critically and provide you with a basic understanding of what the issues may be or the general condition of the property.
If you still have concerns about making an offer contingent on a satisfactory structural inspection, it may be an indication that maybe you should move on and explore other options.
Realtors are usually not qualified to make evaluations of property relative to repairs, problems, previous work etc. but your home inspector should be able to.
There are situations where the seller won't know...or won't investigate. Normally these are flippers or investors. Also sometimes Trust Sales will be like this.
The most important thing is not to rely on others to tell you the condition of the home. Hire a good solid home inspector and see what they say. Building permits should be on file at the Building Dept of the city as well.
The home inspector should be able to give you guidance on other potential problems....or reassure you that it's basically in good shape.
Best of Luck.
