You do not need a "company" to get a mortgage. Any person who has cash put away can loan it to you if they want to.
I once borrowed enough money from a cab driver, to buy a house. The whole thing. No credit check. No nothin', not even an apprasil.
Here is how it went. I had a title company do the work. They prepared a deed from the seller to me, and they prepared the note and mortgage. The funds borrowed from the cab driver were secured by the note and mortgage (signed by me). I then owed the cab driver. He also put up the funds for the title work and the title insurance.
Then the title company told the cab driver (the lender) how much money they needed from him. He gave them a check. They dispersed the funds to the seller, for their fees, and the recording of the documents.
Done deal, I owned the house, the cab driver held a note for the amount due from me, and the seller got his money, on the spot.
The cab driver and I setteled on a payment amount and an interest rate for the payments that were due to him. That info was clearly spelled out in the note.
The interest was more than he could get in any kind of CD commonly available at the time and less that the going rate for mortgage loans. Good for everybody involved (the "Company" was not involved).
There are lots of people who have money put away that is not making a very good return (even cabbies) Find them, and do business with them. They do not know that you have a good deal until you tell them.
