-Has no crawlspace (common for older properties) so we couldn't see the foundation-Drywood termite/wood decaying fungi damage seen on all the windows/doors/parts of the beam on the exterior, parts of roof decking and rafters in the attic-Old leaks/moisture damage seen in the ceilings and attic-Parts of the roof has patch work-Roof doesn't have any permits on record (don't know how old it is)Seller's offer to me:-Fumigation treatment for drywood termites (tenting the house)-Replace and repair all damage wood throughout the house-Replace the entire roof with a new permit-Replace one window in every room (not all)-Pay for a structural engineer to inspect the foundation-Offer to get quotes for repairs and have a 15-20K budget to make all repairs, house is 500K.

Also, engage either an architect or civil engineer, or both. 

I know you weren't trying to be snarky, but it also sounds like you've drawn a conclusion here that I wanted mommy and daddy to get me out of tax jail, and that I came to BiggerPockets in the hopes someone would reverse-engineer the ethics of that for me.

I'm 24, working in the Texas oilfields, have a Mechanical Engineering degree, and sitting on some cash.

But I'm no structural engineer I'm just someone with some guesses about it.

Unless you have a background in petroleum or chemical engineering or have one doing your due diligence then I would suggest that you walk away from this area.

Like ourselves, we're not the largest or highest positioned on search engines, but we're all "hands on" (doing the work ourselves, no salesmen!)

Thank you for the infomation, Kenneth.I'm partnering with a land developer who has 20 years successful experience in this industry.Furthermore, he knows the head of the county, engineers and many others.The properties are way below market value.With that said, there is almost no room for mistakes. 

Now of course for a new build, or a major remodel, you will have to get an Architect and an Engineered set of plans, and submit plans to the City and a Plan Check company.
