The home was built in 1940, and I think most of the stuff is original. 

The deed is the deed...it's not like a contract that you can change unless there was typo in the original deed in which a "correction deed" or similar form deed will be filed after the fact.  

Their interest rates will be higher and they collect origination fees so the purchase price of the property is key and determining your ARV. 

consider the opportunity cost of doing this#1) sell house for cash or to a buyer with their own financing from a bank, etc and you get 315K at time zero, you invest that at historic SP500 8.4% return over last 220 yrs and it grows to $3,541,514.46#2) do owner financing and you get 100k up front that invested at 8.4% grows to $1,250,000, plus you get your payments at $1400 x 360 months or $502k, invested grows to $3,265,000 total including the 1.25 mil aboveso you come out 300k better not doing it and you don't have to service the loan and all the other risksremember banks don't even carry mortgage notes after origination, they dump them onto the US taxpayer via illegal-unconstitutional havens like Fannie/Freddie/HUD, and for last 15 yrs the FED has bought every MBS in the country, which frees up the Banks capital to do it again and make the real money on churning the points and feesplus will next 30 yrs have higher inflation than last 30 yrs?

Most note investors originate new notes or purchase existing notes (sometimes at a discount to principal)..  

Already determined:Sell price Buyer pays all fees, no appraisal etc.What they are now asking (opposite from original post):86% downSeller Finance remaining 14% over 6 years with interest only payments first 3 years and interest plus $1000 last 3 years.

My friend that originally told me about that company in COsta Rica ended up changing to the company I found. 

Oh, and just some quick math if you haven't already done so, your remaining VA qualification through entitlement is calculated by subtracting your original VA loan amount from your first purchase price against $766,550 here in Florida, and that is the maximum purchase price that you can qualify for, with a second VA loan, without having to put extra down payment. 

To answer your original question about making it more palatable for owners....you need to pay them for the service of providing you with debt. 

I originally think that Florida's insurance is off control, then I found the NC properties' insurance increased 40% from last year and tax will increase also.With current inflation(3%, 30%, or 300%), more and more people can't keep a home in most place although the interests maybe under 4%.
