It seems that all posters above are focusing on building code which is irrelevant decades later.Municipalities enforce the maintenance code in the present for preexistent structures.

The new buyer would have to honor the pre-existing oil rights of the oil company.My question is: is it possible to transfer oil rights but not mineral rights?

This form allows them to note any pre-existing damages and accept the unit as-is.

But I do have an issue with asking some of these pre-existing cabin owners to have to retrofit their cabin with the system and expecting them to have it done in a year or something. 

If you buy pre-existing, you'll still be looking at 400k or above.  

I'm not against innovation but every point you raise is pre-existing or illegal/ against regulations. 

You'll likely pay high premiums, face lots of claim denials due to "pre-existing conditions", and deal with service delays.

COLLUDE With Judges like KAREN PHIPPS to case FIX court case outcomes so the public doesn't know their fraud scams that include insurance faked claims with frivolous incident dates of known pre existing conditions putting tenants lives at risk SEE CASE COLUMBUS OHIO FRANKLIN COUNTY COURT OF COMMON PLEAS 22CV003620 AND OHIO SUPREME COURT WRITS : 2024 1311,1314,1315,1319,1320,1339,1360,1362,1378,1400,1420,1448,1471,1474,1502,1588,1601See FRANKLIN COUNTY MUNICIPAL COURT cases 2021 EVH 060439 AND 2021 CVG 020711 FAKE AND UNLAWFUL LANDLORD RETALIATION EVICTION BY ALL COUNTY NEO'S  ATTY WHO IS THEIR CLIENT🙄THEY ARE ALL CORRUPT and fraudingI would be careful about labeling an attorney as a fraud on a public forum.

That way they're not soliciting you w/o a pre-existing relationship, and you still get to look at their work. 

I am open to the idea of building a duplex or purchasing a preexisting home.
