Rafter Cracked
OK, so you didn't have to pay for an inspection, why not spend a couple hundred bucks to get a structural engineer to look at the attic. In my experience as a Realtor, most good engineers give a detailed report including the proper fix. In many cases, the fix can be done by the buyer or current homeowner themselves. Or, if you choose to fix without having an engineer check it first, have one look at it after the repair to make sure you've done everything correctly. This is a serious concern and should be checked by a professional. Good Idea Morgan.
If I become the primary, I will do that, among other things. The inspection report revealed lots of (what in my mind) little things-no GFCI and some 'amateur' wiring, inadequate vapor barrier in crawl space, boiler not elevated properly, hot water heater flue too close to insulation in attic (and no fire proof barrier), inadequate wall between garage and house, some pest droppings (house has been empty for several months-its being sold as part of an estate), etc. So there will be lots to fix:/It's on water though and the price is good so I really want it. Seller isn't going to fix any of these things (I did get them to give me $5000 at closing toward a new roof which is nearing the end of its life according to the inspection report). This info you just shared can all be explained by codes. When they were done, ( flue, floor clearance, etc.) were probable not written into the codes like they are in today's codes. Homes being sold as part of estates are usually sold for money and hold no emotional value to the seller.

It sounds like everything you mentioned would not stop me from purchasing the home. If the home fits your want list, and every thing is fixable, go for it! You have nothing to lose and it sounds like a great investment!
