@Christian EfseaffSo I used the bigger pockets rental calculatorhttps://www.biggerpockets.com/calculators/shared/6...This is the link.

We're doing our due diligence as well in reaching out to all options (traditional banks, community banks, credit unions, online options, etc).

Being that I am self employed and unable to get traditional financing, I am looking to go the route of seller financing.

@Christian Wathne The two flips are dated mainly.

Some months, I am getting 2.5x the amount of income from a traditional long term tenant.

My mortgage lender says that if my rental income is from my own unit it cannot count on a traditional mortgage, but I can count a percentage of the other unit. 

This is what I am seeing:Initial interest rates are lower than traditional fixed rate home loansYou'll enjoy a guaranteed interest rate for up to 10 yearsGives you the most home for a low initial paymentThis all sounds good.

Current owner has had the house over 5 years and it has some significant deferred maintenance but none of the traditional red flags like structural/foundational issues etc.

My loan was traditional loan with a Mortgage company with 25% down.

Your buyer won't be able to get traditional financing, as you don't own it yet, and that will come up in the title search.
