Second lien at sheriff sale

[Ronald Ty]

I went to research and this a revolving line of credit of 50k. Homeowner (deceased) purchased the home in 1985 for 50k. In 2003, there was 2nd lien for 50k that was listed in the original docs as a mortgage and promissory note. It was for 360 month (30 years) & had an escrow. It showed regular property tqx payments to the county.

my guess is there is no 1st mortgage. Maybe they decided they needed the $ later and took out this? But why would it be then listed as a second? There wouldn't be any collateral (the home) as a second?
