Typical promissory note, aka seller financed mortgage

[Justin Decker]

Doing our first seller-financed house purchase (rental property) and the note (mortgage and security agreement) is very detailed and long, with all kinds of insurance stipulations and mortgagee rights of inspection.  We're putting 200k down on a 260k property (60k note).  Seems awfully legalizish and unnecessary... i understand the lender needs protection, but 20 pages?

 Just curious as to what is 'normal'.

Anyone have some examples?

thanks,
Justin
