I plan to mail out a one page letter to 7000 recipients per month.

Would the full 128K be seller financed or just portion of it example 100K then at a 5 or 7 year balloon the remaining 28K or remaining balance of the 128K be paid in full.2-since 51k is owed as a refi, is it treated just as the same condition as a regular mortgage would when it comes to seller finance.

I purchased a home via seller financing, we did ours on a 3 year balloon.

If you have to finance, a pre-approval loan letter that says how long it will take to close you and the maximum amount you are qualified for.My father has been acting as a broker buying and selling real estate for about 45 years and he has taught me a little bit.  

Alright, so I get a lot of questions of how to successfully do a Yellow Letter Campaign and these are the steps I take. 

I wrote a personal letter to the seller explaining my intent and future goals.

Currently, I am mailing letters, and I've sent out postcards in addition to driving for dollars.

Here are the numbers: sixplex in hickory NC Price: $160,000Gross monthly Rents: $3,050 (definite possibility to raise rents by about $25-50 each) Expenses: (50% rule for now): 1,525 NOI: 1,525Cap: 9.5%Debt service: 25% down, financing 120k @ 6% amortized over 20 years, with a 10 year balloon. $860/month Net monthly profit: $665Cash on Cash: 19.95%Any thoughts on this deal?

I have heard some people say they've always written letters by hand, and others say that is a waste of time. 

It would not be too defensive about this but get a loan Pre-qualification letter from a lender and have it state how long it will take to make a closing and a maximum amount.
