I had zero control on Wells Fargo selling my loan to XXXX XXXX Loans ( for XXXX % of the balance of the loan, according to internet research ) Did Wells Fargo get paid from HUD as this was a FHA-Insured loan, then sell it to XXXX Trust for a discount, then buy it back, changing the terms of the approved, signed ( XXXX/XXXX/XXXX ) modification agreement? I believe they have and this is why ; XXXX/XXXX/XXXX - I signed the XXXX modification agreement, with these terms : Total Monthly Payment {$1200.00} ( {$850.00} Interest, {$390.00} Escrow ) *Ancillary Monthly Payment : XXXX - *Ancillary Monthly Payment : This includes some or all amounts that Servicer has advanced for real property taxes, insurance, water liens, or other amounts that XXXX have become due with respect to the Property.
