I've already verified that it can be done as I've paid off the ones that were with Freddie Mac (or Fannie Mae).

Verifying last 2 years of rental history very important!

You can do all the prequalifying from anywhere via credit check, call references, verify income etc.Make sure you have a handy person, ac person, plumber, etc etc that you can call when you need some work done. 

No persons of contact with the company can be verified.

Also these deals are not one out of 100 they are the last 3 i have closed on to keep, you can verify on the county site.

Also you would not reduce the price because of the interest payment. that is not how it works.3. yes the note could be sold, but at what type of discount and what if the borrower stopped paying.while there are a lot of posts on seller financing, some estimiate less than 1% of all transaction have seller financing and the ones that do are first position only with an average of 30% down payment - most of these are to people who do not have verifiable income.Thinking you will get conventional financing then seller financing will be uphill battle as the conventional lender most likely will not approve a 2nd mortgage for purchase.not trying to dissuade you, just wanted to provide some key insights so you do not spend 1000 hours chasing something that is impossible to find.

only small builder or home are not selling fast enough would consider sell to investor.Anyone in Knoxville could verify this or comment or connect me with builder. 

You'd be surprised how often a deal can happen using this strategy but it is also important to run the numbers and make sure your COC return, etc are in line with your expectations.Probably the lowest risk is partnering because a seasoned investor will verify the deal (hence their participation) and likely take care of the initial money required.
