Navy fed’s program offering greater than 100% are probably tied to VA loans in which case they are insured by the federal government. If someone defaults on this type of loan the bank gets paid back a high percentage on each dollar (I don’t have the speacific amount) Student Loans and SBA loan are comparable. Student loans are 98 cents on the dollar that lenders get paid back for defaults. SBA loans I am uncertain about. Probably 75 to 80 cents on the dollar.
