I like audioloss.com and hearingfailure.com - they could both be developed. Maybe a troubleshooting site for the first and a medical site for the second. Both could then be monetised with a clear route to affiliate products, audio cards, speakers, sound equipment, medical services, implants etc. I would say undeveloped though low $xxx but definitely worth building sites in my opinion.
I am not a fan of the others. findstorages is plural - doesn't make sense here. creditamendment - can't see a route to monetisation. petfoodmenu - is this even a thing? recordbooths - maybe in the 80s
